PCB Component Placement Tolerance

A fabricated (bare board) PCB sitting on pick-and-place machine rails

PCB component placement tolerance is a function of IPC footprint tolerancing and various stages of board processing accuracy. PCBs always have to do more with less. Miniaturization of electronics is a welcome development for consumer devices, but comes with additional complications for the designers and manufacturers. The product development team must optimally determine the best […]
