Tips On How To Minimize The Cost Of PCB Prototype Building

Getting your new electronic product design ready for mass manufacture and PCB assembly includes various steps and risks. I will give a few recommendations about how to eliminate expensive mistakes and how to reduce the time to market for your new product designs.

After you have the design for a new product, you want to manufacture some samples. This will guarantee that your device will meet the performance criteria. Simulating the performance of your product is frequently done before beginning to assemble prototypes. Common design software including PCB and industrial design packages will allow you to simulate numerous performance aspects including electrical, mechanical and thermal performance. The simulation results often permit you to find mistakes and help you improve your design. This will save time and money by reducing the amount of sample iterations required before mass production.

If you are designing a difficult device, you may want to think about a modular design in which all of the main features are located in individual modules. Throughout your testing, you can then swap modules that do not meet the design constraints. Replacing a single module will be fairly cost effective. In addition, performance characterization of modules will be faster than characterizing the whole design.

As a result of the setup cost, PCB components are often assembled manually during the prototyping phase. Though, this approach is relatively time consuming. Another concern is the lower reliability and quality of manually mounted boards. Subcontracting the prototype manufacturing provides higher quality. It can also save a lot of time.

To mount circuit boards, your vendor has to set up the production line for your board. This step is quite time consuming compared to the manufacturing time in case of sample runs. Therefore you ought to look for a vendor with a relatively low setup cost because this cost is going to be the majority of the prototyping cost. To reduce setup cost of PCB prototype manufacturing, suppliers will combine boards from numerous clients. This will distribute the setup cost amongst numerous clients. Consequently, you will only have a limited choice of PCB materials and thicknesses.

When looking for a supplier, you ought to however not focus on low setup costs alone. Choosing a manufacturer which can also run production quantity runs later on will avoid a lot of problems during the production stage because the sample data can easily be reused. If there are no major modifications in your design, assembly can begin quickly. The production data are already available in the manufacturer-specific machine format.

Some PCB suppliers also can assist you throughout the design by offering in-house PCB design. If you are not very experienced in the design, you might want to consider selecting such a vendor. Such a supplier can also much more simply and much more rapidly solve design-related problems.

Component purchasing is a big problem when assembling samples as a consequence of the low volume and the ship expense and minimum order quantity requirements of some suppliers. SMT parts are mounted by mounting them as tape in feeders. Assembling small quantities of parts however is a problem because they do not mount in a feeder. If you select a vendor that has inventory of normally used SMT components that you can purchase, you can save a lot of time. Also, you won’t squander any parts which are left over.

Picking a vendor that is also able to do the finished product assembly minimizes time to market by avoiding ship times among various vendors. Also, circuit boards that are found to be faulty during the final testing can be repaired much more quickly. Finally, make certain that you are able to without problems communicate with your supplier. This will help avoid expensive errors and shorten production preparation times throughout all steps of PCB manufacture, PCB assembly and final product manufacturing.
