Ensuring Accurate Placement
Component assembly is ripe for defects. Here’s how to avoid them.
Placement must undergo various checks to ensure components are the correct ones and to locate potential problems. The first check is at the SMT stage. Called a feeder component check, it involves identifying each part on the reels or trays and matching them with the bill of materials. Quality Control checks item number, component size and values, and ensures that what’s called out in the BoM is what’s on the specific reel or tray.
