The Steps

SparkFun has some very unorthodox methods for assembling electronics. We’ve compiled some of the steps and the lessons we’ve learned over the past decade of DIY PCBA (printed circuit board assembly).

We are going to start at the front of production. This means the design has already been vetted, prototyped, reviewed, and ‘gone to red boards’ (once a green colored prototype is ready for production we have the PCB made in red). Now we just have to build the thing!
