The accuracy of your PCB’s fabrication begins with your design files. If you stray from the best path, you may experience PCB fabrication issues and extended turnaround time for your PCB.
Creating PCBs also requires precision, as there is a “best path” that takes your design through fabrication to an accurately constructed board. I always enjoyed archery because determining the best path to the bullseye involves a high degree of precision. At camp, we could participate in all kinds of activities like hiking, swimming and archery. Back when I was a Boy Scout, the best time of the year was going to camp.
