When I was younger I used to help my father-in-law work on cars; including mine. He was an experienced mechanic and I was a novice which meant that my main responsibility was to “go for” tools when he needed them. I did not mind the job, but I always wondered why it was necessary. Perhaps, having me run for tools was his way of involving me and keeping me interested. But, it seemed to me that it would be easier to just get all the tools together beforehand and place them in easy reach of the car. That way you could repair the car faster because you started the job with all the required tools. You were ready.
Checking off all requirements
When designing and building industrial PCBs, which are boards that are developed to be used in a factory environment, you do not have the benefit of going back for forgotten items. Instead, you must be sure the boards are ready prior to production. Otherwise, you can look forward to wasted manufacturing runs, increased and unnecessary costs and unhappy managers if you are missing delivery deadlines. A reliable way to make sure that your design is ready for production is to assemble a list of requirements to ensure that your production runs will have a good yield rate. Let’s see if we can define the requirements such that your industrial PCB production will achieve this objective.
Requirements for the Production of Your Industrial PCB
Industrial PCBs are boards that are used within production facilities. Typically, they are deployed or embedded in advanced equipment, used in automated safety integrity systems (SIS) to ensure that plant safety integrity levels are met or in industrial IoT (IIoT) systems for Industry 4.0 facilities. As industrial environments are tasked with producing different products, specific equipment and systems are typically customized. This customization extends to the electronics and PCBs that comprise these systems and equipment.
As industrial PCBs are specialized and custom devices they are typically not produced at high-volume. However, it is no less critical that your design is production ready prior to entering the quantity or low-volume manufacturing stage. To ensure this is the case, you should make sure that all design requirements are satisfied such that optimal manufacturing by your contract manufacturer (CM) are met, as presented below.
Industrial PCB Production Checklist
By following the checklist below you are well-prepared to achieve the efficient production of your boards for industrial application.
The list above contains items that should be checked off prior to forwarding your design to your CM for production and following them should yield good results for your industrial PCB production.
Industrial PCBs are typically special designs that are customized for usage in industrial equipment or elsewhere in a production environment. As such, each design has its own challenges, which makes your choice of the right CM more critical. Having a CM that is committed to working with you throughout development to ensure that your design is ready for industrial PCB production can make the difference between whether your design, manufacturing and bring up is an efficient process or unnecessarily costly and long.
