For many reasons, it can be somewhat intimidating when you’re finally ready to bring your PCB design to mass production. There are so many electronics, variables, and design specifics to go over before you actually bring a final iteration of your prototype to mass production that it can almost seem too complex to understand at times. There is, however, a simple formula to use, or series of questions you can ask yourself before you bring your final PCB design into mass production.
Problems with PCBs can happen after many years of use, or PCBs can have malfunctions mistakenly built into the board during manufacturing. Most PCBs problems are repairable thanks to their physical nature.
