We are constantly pushing ourselves for better printed circuit boards (PCB). One thing we've learned is that PCB fab houses (such as Advanced Circuits, BatchPCB, PCB123, Gold Phoenix, Bare Bones PCB, anyone really) have a very hard job to do. Creating a PCB is not an easy task and there are many ways for a fab house to mess it up. Unfortunately, fab houses tend to spend less time on prototypes than on production runs. Therefore, we try to design products and PCBs for 'manufacturability'. This tutorial will show you how to minimize the number of ways the fab house can screw up a PCB.
