Suggestions On How To Lower The Price Tag Of Pcb Prototype Assembly

Manufacturing electronic product prototypes includes PCB fabrication and PCB assembly and is an important step when launching new products

. Based on how far evolved your design is, there is a high risk of expensive errors. I will give some pointers about avoiding common mistakes and how to reduce time to market and cost when making prototypes.

As soon as you have completed your product and PCB design, you want to get started building samples before you commit to large production volume. Many design software packages such as PCB layout design software and industrial design software have simulation capabilities built in. The simulation results frequently allow you to find errors and help you improve your design. This will save time and money by minimizing the amount of prototype iterations required before mass production.

Picking a modular design in which each module contains particular core features will simplify the optimization of your sample by permitting you to switch individual modules that do not meet your performance versus rebuilding the complete design. When a certain module doesn't meet the design requirement, it can be swapped fairly quickly. The time advantage at this step is obvious. During the design stage however structuring your design into modules will require extra effort.

Based on the design complexity, you could consider manually mounting PCB components to save cost. Then again, for medium to large complexity this option tends to be exceptionally time consuming, especially if you want to build numerous prototypes. To get better-quality boards and to avoid problems with particular components which are difficult to mount consider subcontracting the prototype manufacturing. That might also save you some time.

You should look for a subcontractor that has a small setup expense because this expense will dominate the overall expense in case of small-quantity runs. To reduce setup expense of PCB sample manufacturing, suppliers will combine boards from several clients. This will split the setup cost amongst several customers. Consequently, you will only have a limited selection of PCB materials and thicknesses.

Try to pick a supplier that not only has low setup expenses but also can do full-quantity manufacturing runs. Specialized prototype manufacturers might not be equipped to handle larger volume assembly. This has the advantage of simplifying the migration between prototype and finished product. This way your design is already translated into the exact machine data which means little or no setup expense for your finished production.

Some PCB suppliers also can help you during the design by providing in-house PCB design. If you are not very experienced in the design, you might want to think about picking such a vendor. Such a manufacturer can also a great deal more simply and much more rapidly solve design-related difficulties.

Part sourcing is a main concern when mounting samples as a consequence of the small volume and the freight expense and minimum order quantity requirements of some vendors. Small quantities of SMT components are difficult to mount by automatic machines since they usually do not come in reels. If you pick a vendor that carries stock of commonly used SMT parts which you can buy, you can save a lot of time. In addition, you won't waste any components which are left over.

Choosing a manufacturer that is also capable to do the finished product assembly minimizes time to market by avoiding ship times between various suppliers. In addition, circuit boards that are found to be faulty throughout the final testing can be fixed much more rapidly. Decent communications with your supplier is key since it will help avoid expensive delays and errors throughout all steps of the PCB assembly and finished product manufacturing.
