Tips On How To Lower The Cost Of PCB Prototype Building
Manufacturing electronic product prototypes includes PCB design and PCB assembly and is an important step when launching new products. Depending on how far evolved your design is, there is a high risk of costly mistakes. I will give some advice about eliminating common errors and how to minimize time to market and cost when making samples.
After you have the design for a new product, you want to build a few samples. This will guarantee that your device will meet the reliability criteria. Simulating the performance of your product is normally completed before beginning to manufacture prototypes. Customary design software such as PCB and industrial design packages will allow you to simulate different performance elements including electrical, mechanical and thermal performance. The simulation results frequently permit you to locate mistakes and help you refine your design. This will save time and money by reducing the number of prototype iterations required before mass production.
One plan to speed up sample optimization is working with a modular design. A modular design will concentrate core features of your design in particular parts which are interchangeable. Throughout your prototype optimization you can then improve individual modules which do not yet meet your performance requirements as opposed to having to rebuild your entire design. Swapping a single module will be relatively cost effective. Moreover, reliability classification of modules will be faster than characterizing the whole design.
As a consequence of the setup expense, PCB parts are often assembled by hand throughout the prototyping stage. However, this method is fairly time consuming. One more issue is the lower reliability and quality of manually assembled boards. To get better-quality boards and to avoid problems with particular components which are difficult to mount think about subcontracting the sample assembly. That may also save you some time.
When running small-quantity manufacturing runs, the production setup cost is going to usually dominate the overall prototype build cost. When looking for a subcontractor, it is best to pick a vendor which specializes in sample builds to minimize the cost. Prototype Pcb manufacturers typically combine the circuit boards of numerous customers which essentially shares the setup cost amongst a number of customers. The drawback is that you will typically only be able to choose amongst a number of standard PCB material thicknesses and sizes.
Apart from picking a vendor with low setup expenses, selecting a company that is going to also be able to handle your full-volume assembly runs minimizes errors since changing vendors has the possibility of mistakes due to a particular manufacturer interpreting production design data in a different way. Your manufacturer may then very easily reuse your translated design data. This may not be the case if you are changing vendors. Also, chances are that your new vendor will read some data differently which will jeopardize reliability of the finished product.
A few PCB suppliers also can assist you during the design by providing in-house PCB design. If you are not very experienced in the design, you may want to think about selecting such a supplier. Such a vendor can also a great deal more simply and much more rapidly resolve design-related issues.
A difficulty with small-quantity assembly runs is purchasing of PCB parts. Many components vendors will charge ship fees and have minimum order quantity requirements for particular components. Also, dealing with a small quantity of parts is a problem in case of surface mount assembly because components will be mounted from SMT feeders. Some manufacturers carry stock of commonly utilized SMT parts which you can order which will save you the time of purchasing these parts yourself and also eliminates wasting unused components.
If you selected a supplier that also does the final product manufacturing, you will not only reduce time to market but also guarantee that circuit boards that are found to be faulty during the final test can be repaired much more quickly. Good communications with your supplier is key since it will help eliminate costly delays and errors during all stages of the PCB assembly and final product manufacturing.
