A PCB is the acronym for Printed Circuit Boards, which are cards or circuit boards that are composed of a very thin flat metal or hard plastic-type board called an insulator. It is upon this that computer silicon chips and other similar electronic components are mounted. These PCBs are then used in electronic appliances like televisions, computers, washing machines, digital cameras, and so forth.

A prototype can be considered the first working model of an invention. So in this case, a PCB prototype is the first circuit board that is invented for a new electronic device. By using this PCB prototype in the electronic device, the inventor can see if the prototype serves its purpose in the invention. Once the electronic device is made to function with the PCB prototype, any mistakes that take place can be rectified in the prototype. In this way, the PCB prototype saves the inventor of the electronic appliance lots of money, as any mistakes that may be present in the PCB will be pinpointed before the actual commercial manufacture of the PCB.

Without having a PCB prototype, the model of a new invention will be of no use if its PCB is not in good condition and up to requirements. Electronic appliances are getting more and more technologically advanced by the day. This advancement is done through changes on a PCB prototype, which is then tried on the appliance to see if the advancement is in right order. Using different materials of the PCB also account for changes in the PCB prototype. You can use fiberglass, Teflon or cross-linked polystyrene for the PCB, and it is through the PCB prototype that you find out which PCB material best fits your PCB. Nowadays, new PCBs are in use in electronic appliances, thanks to the PCB prototypes.

PCB prototype plays a very important role in the creation and design of PCB (Printed Circuit Boards). The design of the PCB does not depend on single elements rather depends on variety of elements which needs expertise and testing for several times. And prototype gives you the opportunity to check your product before production. Actually, we can say that the design depends on indistinct set of necessities. This is produced to define the required functions for the electrical and mechanical products. And the prototype helps to fulfill these needs by giving you a chance for proving your design.

The designers include all the required functionalities those can fit in the board. As regarding to the requirements, the board changes its shape. Sometimes it’s large with the extensive requirements. And sometimes it’s small with fewer requirements. Again many things are needed to make a PCB prototype of production stage. Among them, functionality with reliability is a must. The complexity and functionality determines the required number of layers. Some board consists of only two layers as they have less functionality and some have even more than 32 layers for their complexity and high functionality. And the size also differs a lot. As the board has to sit perfectly into its desired system, it must be made in the perfect shape. The tolerance is also a factor as the layers and copper traces certainly depend on it. Most PCB has a design with a tolerance that makes the layers and copper traces even more critical. As they are designed with highly tight tolerances, they are made highly integrated. And this integrity sometime causes some critical problems. So, it must be checked carefully for the accuracy. The voltage must be moderate with the application and the signals must also be clean. Again, the surface components must meet the required tolerance. And after considering all these respects, the developed first board is called the prototype. These are developed for testing. They are mainly made depending on the number of testing required. After the testing is completed, the production begins with the design.

These PCB prototypes are checked in all critical conditions as everything must be checked and every problem must be solved before the production. Again, the leads and traces are re-measured so that it meets the required thickness. The VIAS and holes need individual programming for each board and their making process is also sophisticated. The tolerances and electrical signals are tested even after the addition of the surface components. When all the components are added and it is made as the specification, it is finally tested for several times for the required result. The board must also be able to provide proper reliability and effectiveness. In this time, the board is tested without planting it in the environment it is made for. And all steps are recorded.  And when it meets the standard quality, it is sent for production. But if any wrong occurs, it is tested again and sent for further solution. Even sometimes the whole design is changed for the failure in tests.

The prototype is made by the companies to check their products and inventions before manufacturing. And thus it helps a great deal in the development of PCB.

Tapping into the growth means working at space-age speed, making prototypes of connectors or other wiring harness parts with a computer-guided rapid prototype machine that lays down thin layers of plastic or rubber over numerous passes, like an ink-jet printer producing a photo.

Automakers aren’t quite ready to start making Jetson-type flying bubbles, but they are cramming today’s vehicles with electric motors to power wheels, sensors to deploy airbags and entertainment devices to allow adults to survive a cross-country trip with children.

Connecting the electronic gadgets are as many as 2 1/2 miles of electrical wiring that, along with 600 plastic connectors and as many as 2,000 wire terminals, all weighing as much as 132 pounds – much of it coming from Delphi Packard Electric’s Customer Technical Center in Champion.

”Demand will grow like crazy as we go to electric motors. That will drive the need for more connectors and wiring from Delphi. We want to be a part of that growth,” Chris Burns, director of global innovation for Delphi Corp.’s Electrical/Electronic Architecture division, said last week.

So do Delphi Packard’s hourly production workers. Tom Krolopp, shop chairman of International Union of Electrical Workers-Communications Workers of America Local 717, said the tech center provides more work for his 665 members, who make plastic connectors, metal terminals and electrical cable used to assemble wiring harnesses.

”Look at the projects for all-electric cars. They need a lot of wiring and plastics,” he said.

Since the auto supplier’s exit last October after four grueling years in Chapter 11 bankruptcy, Delphi Packard is counting on its patent-producing corp of engineers at Champion and five other tech centers worldwide to keep it in the forefront of an auto industry that’s moving away from strictly oil-based fuel to hybrid or total electrical power.

”We can turn ideas into parts you can hold in your hand in hours,” said Jerry Rinehart, supervisor of the rapid prototyping and CT scanning department.

It means developing thinner, lighter wiring, allowing automakers to fit harnesses into smaller vehicles, boosting fuel efficiency while still stocking them with navigational systems, computer ports and other electronic content that customers are demanding.

The division became one of 28 finalists worldwide for the prestigious 2010 PACE award for its environmentally friendly ultra-thin wiring wrapped in halogen-free coating that makes it recyclable, thus keeping it out of landfills.

The 0.13 millimeter-squared, or 26 gage, wire is the thinnest that can still be plugged by hand into connectors. Thinner wires require a special machine that Delphi Packard also has developed to make the connection.

About 200 engineers, technicians and other workers at the center on Research Parkway N.W. are welcoming the challenges.

”We’re tireless here in trying to stay in the forefront of technology. We want to become the technology leader” in automotive electrical and electronic architecture, Senior Project Engineer Bob McFall said as he showed off the center’s process lab, a factory-like setting where engineers run through a complete manufacturing process, from cutting electrical cable to length to producing the final harness as fast as a 1 1/2 days.

”We don’t have the traditional lead time; that’s what drove Delphi to invest in this area,” Burns said.

The lab also gives Delphi tools worldwide to develop cutting-edge wiring and sensor systems for future hybrid gasoline-electric and all-electric vehicles.

Delphi engineers have been working alongside their Chinese counterparts in Champion on prototypes of 10 wiring sets for an all-electric vehicle for CODA Automotive of Santa Monica, Calif.

The sedan, which will be built in China for sale in California later this year, is projected to have a range of 90 to 120 miles. Delphi will supply key electronic and high-voltage parts, along with a multiservice antenna.

With its six technology centers -Champion and the Wuppertal, Germany, center are the largest – Delphi can offer customers global cooperation for engineering-intensive projects, Delphi spokeswoman Rachelle Valdez said.

Some of the ideas the tech center is studying verge on the Jetson-like future. Burns said engineers are looking at ways to charge an electric vehicle’s batteries wirelessly.

”There could be a mat in a restaurant parking lot where the vehicle could be charged while the people were eating in the restaurant. The cost would be added to their bill,” he said.

A conventional approach would be to take surfaces and ideas from aerodynamicists, convert them into either rapid prototype parts or scale models of the sort of parts that you see on the race cars, and then put on a very large scale wind tunnel model and test them in a wind tunnel. In our case, our system involves taking those shapes and instead of making model parts we actually essentially mesh them and create an extremely sophisticated computer simulation, consisting of hundreds of billions of cells in a CFD model and essentially flowing digital wind, if you like, over this model in a variety of different simulations in a variety of different conditions.

Prototype machining is preferred when it comes to trials. Developing a new concept is difficult and time consuming when the process is vague. To ease out the problem of losses such type of prototyping can be done. It shows how the machine will react under certain circumstances. There are units that defy and capture every action of new made machine. Use of prototype machining is basically done when there is a need to create a sample machine. Well, use of this sample machine can be for various purposes. It can be creation of new technology or even creation of new product. If there are any types of modifications required then it can be solved then and there itself. It also shows if there is a need to change or alter any specific process.

The internet is the preferred source for prototype machining. The internet is filled with such machining websites that offer high end services. Online deals are preferred since all the care and troubles is taken care. Most of the websites will give free delivery service; it will save huge transportation costs for which you might need to shell out of your pocket. Price comparison is another feature that can be considered when making an online purchase. Since there are numerous websites posted on the internet, you can easily check for the preferred website available at low cost. You can even check for the type of service given with the deal. Quality is something that you need to be well versed before approaching such sites. There are past testimonials written by clients that can be checked to know the reputation of the company. These testimonials will give you a broad idea on their customer service.

Prototype machining is therefore the preferred tool for industrial planning. The company need not waste huge amounts by giving a final order and then repenting for its losses later. Instead they can create one, test it, alter it if required and then give the final order for production purposes. It is the preferred way to solve development problem. Different types of designs and technology can be tested with the use of such machining. It is advanced and programmed with the use of a computer. All the programming steps are taken by the onboard computer which is installed in the device. Basic and advanced types of jobs are also taken care by such machining services for prototyping requirements.

A new development method may allow breaking away from the pack as rapid prototype Shenzhen companies continue to employ outsource facilities that offer flexibility and foster innovation.

Innovation, whether through the development of new products or processes, has become crucial for companies in virtually every industry. New technology holds the key to competitive advantage and, perhaps, survival.

For manufacturers, the problem is particularly acute because of the ease with which competitors can outsource production. No longer can mature companies, with established manufacturing bases, count on an economy-of-scale advantage as a barrier to entry from new competitors.

Pressure longxiang-ltd.com has worked with hundreds of customers from the large multi-national corporations to small entrepreneurial start-ups, applying unique configurations of equipment and extensive chemical expertise. These efforts have often resulted in new products, processes and, at times, new business segments for the client company. As expected of developmental projects, however, many failed to produce a successful innovation, though, in retrospect, a large number of the attempts did yield substantial savings for the sponsoring client. Early “failures” have prevented a company from making large investments in a process that wouldn’t work as anticipated or in a product that couldn’t meet the performance and economic needs of the marketplace.

“We’ve been able to observe scores of successes, near misses, and failures — the entire range of potential results,” says Larry Rosen, CEO of Pressure Chemical. “In an effort to improve our own internal processes, we began to examine the data closely and realized that we had learned to do things in a new and different way, having seen the best and the worst of all the organizational processes used by our customers.” With the help of an outside consultant, Droz and Associates, we cataloged our new products and processes that illustrated a variety of circumstances, parameters and goals. The consultant found that our method was a radical departure from traditional budget-driven, stage-gate approaches.

Although attempts have been made to improve the traditional method, such as the CPM (Critical Path Method), a joint venture between DuPont and the Remington Rand Corp., the approach was flawed. The Japanese, perhaps driven by their respect for W. Edwards Deming, evolved a step-gate method that looks back periodically to correct the trajectory of a project. Still, something was lacking.

Droz helped us to conceptualize the approach in a graphic manner that illustrates the central distinction of this cyclic route from the traditional straight-line approach. The key benefits of this novel approach, which we call Concept to Commercialization (rapid prototype), are reduction in time, cost and risk, akin to a hat trick in hockey, according to Rosen.

The goal of a recent project, undertaken for a major international manufacturer, was the hydrogenation of a polymer for use in high-capacity data storage. This client chose to outsource the project because of the diversity of appropriately sized equipment available in our facility. The base polymer had been produced by the client in its large continuous production facility and the scope of work was limited to hydrogenation. Unfortunately, market testing of the target product revealed that its properties failed to meet expectations. Because it wasn’t feasible to interrupt commercial production to produce small quantities of differentiated precursors for further work, the client faced abandonment of the project.

In discussions centered upon future windows of opportunity to process additional samples, the client was introduced to the variety of Plastic mold resources and interdisciplinary team of specialists that could be assembled to move the project forward without substantial delay. The proposal presented to the client expanded the scope of work to include creation of a small polymerization system and synthesis of the triblock coRandpolymer precursor. Within three weeks, the project was back on track and demonstrating the best features of the nascent rapid prototype Method.

Wireframes & prototypes didn´t use to be a priority  for IT professionals. But as the IT industry develops, it becomes essential to build websites or apps on solid foundations. Here comes a non-exhaustive list of why we should all be using wireframes and prototypes more often.

We speak different languages

Imagine an English developer having to explain a future website to his client, a chinese businessman… I think this speaks for itself. But we don´t need get to such extremes, the very same word can have different meanings for people that speak the same language. But simply because they have different backgrounds they won´t intend the same things behind a common concept.

We need to visual the future product

An image is worth a 1000 words! This is actually why we wireframe in the first place (and incidentally, reading all the specs doc of a future website is a pain, I wonder how many actually do it). Even if it´s only a sketchy wireframe, at least everybody sees where is what and how it looks like.

Clear up your ideas

Get things clear! Wireframes and prototypes help you to organise and share your idea avoiding misunderstanding. You´ll see what´s possible and what´s not.

Save time (it´s quick)

Because with a prototype in hands, you know what to expect as a final outpout. Hence prototyping will save you time during development and avoids rework being done too. A prototype is also quickly shared & commented among collegues and you can apply ongoing changes to it so you see in real-time what´s being done.

… and money (it´s cheap)

Time is money, everybody knows it! Whether it´s on conception, design or development, saving time most certainly means less man-month! Plus, the whole point of a prototype is to save time, so it´s usually developed using cheaper & easier technologies than the one that will be used for the final product.

Anyone can do it

No need to be a high-profile developer to do a prototype. Actually, it´s quite the opposite. If you want to build a good user interface, you might want to ask a UX designer, or designer to build what usually a simple HTML prototype. Moreover, with high-fidelity prototyping softwares, everybody can create fully functional prototypes without a single line of coding.

Run user testing before development

This is probably the main advantage of prototyping! Prototyping the UI of a website or an app lets you carry out user tests before developing the final thing. This is also a big difference between functional prototypes and static wireframes, as the latest doesn’t allow you to do this.

All in all, although wireframes are very useful when it comes to define and analyse a website or an application, these arguments shows that it´s best to prototype. Prototyping will “fluidifies” all processes of any IT project, from design to development and testing. With RIA & dynamic websites the need for prototyping will be increasingly present.

Rapid Prototyping Comes of Age with This Solid Freeform Fabrication Kit

We’ve been waiting a long time for a product like this and now it has arrived. For the home user and those who don’t have ,000-,000 to drop on a high end rapid prototype unit, the Fabber gives the tools to build your own home manufacturing system that can build just about anything as long as you can design it. Designed by a guy who got tired of losing Lego pieces, the Fabber lets anybody have a desktop Rapid Prototype unit that can manufacture pretty much anything – let’s have a look at this dynamic hobby tool.

Solid Freeform Fabrication or Rapid Prototyping has been around for quite a long time now. Many commercial companies offer various type of machines that can manufacture high precision parts out of both plastic or metal to exating tolerances. The downside, they cost anywhere between ,000 and upwards of ,000. Some machines can even run up to 0,000.

The Fabber is a joint project started in the Computational Synthesis Lab at Cornell by Dr. Hod Lipson. He initially visualized the Fabber as a tool to reproduce lost Lego pieces. It is a low cost reasonable detail sold freeform modelling or fabrication tool with a build volume of about 512 cubic inches. or an 8″ cube.

What the Fabber really represents is a grass-roots approach to what has been a niche product for more than 20 years. As they explain, they are comparing the Fabber to the Altair 8000, one of the first microcomputers and one of the things that triggered the home computer boom back in the mid 1970′s. The Fabber even costs about the same with inflation, at about 00 for parts, whereas the old Altair would have cost about 00 in today’s dollars.

The real beauty of the tool is that it is all made from off-the-shelf components. For a little over ,000 you can buy the complete kit and put it together, or buy a fully assembled unit from a company called Koba Industries, which has partnered with Fab @ Home to build and sell the product at only a little bit above assembly prices.

The Fabber will take a standard STL file format used by any of the 3D design applications and produce an actual model based on that file. They have used the Fabber to produce a watch with embedded electronics, a working flashlight with circuitry injected, as well as some other really cool things.

This is a brand new technology and certainly not as refined as the high end production machines that can be bought for multi-thousands of dollars. But as a concept, it’s something that can be developed and evolved. All it takes is ingenuity and a desire to see how far you can go.

What the Fabber is specifically, is a Solid Free Form Fabrication tool. It uses a lifting table combined with a XY axis stepper motor that guides a print head or engine that contains a number of syringes. Each syringe can hold a different fluid material, and depending on the size of the nozzle, you can potentially use the Fabber to build very small and detailed objects.

From CAD to prototype

When designing a new product, or revising an existing one, designing and getting a prototype of the Printed Circuit Board (PCB) is often a difficult and expensive task. If we examine why this is so, we will discover ways to make the process easy.

Like any other product that is built to your specification, a new printed circuit board has some up front costs that are the same no matter how large, or small the production volume is. To design a new board, or revise an existing one, will have an engineering cost. There will also be a cost to making a new solder mask for the new board. Remember whether you change one component or you completely redesign the board, any change from an already paid for solder mask, will require a new one to be made.

It is a common misconception that a small change in the PCB, should have a small charge to realize this change.  As you see, a change is a change regarding the cost of printing the board. It also does not follow for the engineering. It is often the case that someone has a product designed years ago by one engineer that they want slightly modified by another engineer. The new engineer will need to review the existing design to see how best to implement the desired change.

This can be frustrating to the company paying the bill as they can feel cheated to pay nearly the cost of a new PCB when they just want to modify their existing PCB.

The way around this is to plan ahead when you are designing PCB from scratch and work with a firm that will help you do this.

Let’s take the example of a PCB that in addition to power and a power on light, will have 2 inputs and 2 outputs. It is possibly, if not likely, that additional features are desired for the next iteration of the product, let’s say 4 inputs and 3 outputs and a display. The details of this desired iteration are not to the forefront but it is logical that the next iteration would benefit from this, sometime in the future (this can be even years later).

Remember, there is a fixed cost to the solder mask and the engineering time. The added cost of engineering the future desired features is negligible compared to the cost of designing from scratch. Just because there is circuitry on your PCB does not mean you have to populate it when you have boards made.  You can in essence make a board that has two revisions.

While it is true you will still have to make modification to the software in your microcontroller, this will be easier and cheaper than revising the entire board.

This will be especially true if you keep good notes on the board and a good copy of the software with notes to where you want to modify it.

When you are seeking to have PCB designed and built, look for a firm that will help you work through these issues. Use their expertise to see what is reasonable to plan for and what is not. If the firm you are working with does not want to help you with this; look for another one that does.

Permit me ask you: what would you think if you hear that you will generate a part on a PC and then you will hold and evaluate that half 45 minutes later? As a matter of reality, it’s not just my imagination – it’s a reality! What would are unbelievable several years ago is now well established technology due to three-dimensional rapid prototype printers build it possible.

You need additionally to stay in mind that there is a method of creating prototypes involved 1st creating 2-dimensional drawings of a half and then taking those drawings to a model maker to form the prototype. This plays a important role, the model maker would initial have to correctly interpret the drawings, and then a process for making the prototype was identified. To the best of our data, once the half was created, the engineer ought to examine and live the part carefully to create certain that it fell inside the specifications on the drawings. We have a tendency to have every reason to believe that if it did not pass inspection, the half would wish to be modified or scrapped and the entire method would begin everywhere again.

However currently there’s an alternative to the current method: imagine taking the same part that took days or perhaps weeks to make and having it in your hand in 45 minutes. The process is kind of incomplex: a part is made digitally on a pc using 3D modeling software. As way as it’s ready, the file is then saved in a common format and sent to a 3D printer. The other useful thing to feature is that the printer builds the half one skinny section at a time from the bottom up putting water soluble supports in where necessary.

Really, it takes from 20 minutes to many hours to complete relying on the scale and difficulty of the part. What’s more important, the part is off from the printer, placed in a very detergent solution to dissolve the supports, rinsed, dried, and is back in the engineer’s hands on the identical day. In addition, it should be additionally said that the dimensional accuracy of the part is in fractions of a millimeter, thus most elements do not require further measurement and verification.

It’s no nice surprise that it virtually sounds too good to be true. Not to mention, these printers have become relatively cheap in recent years, and whereas there are still some expensive models, of course, there are very useful 3D printers that are relevantly not expensive.

Therefore, to form long story short, the process of making the rapid prototype doesn’t take long as to the time, material, and labor savings and your money would be paid off terribly fast. To sum up, 3D printers are by way one among the most intriguing components of digital rapid prototype, and the printer build the part one layer at a time quietly.
