PCBA Inspection Concerns
PCBA Inspection Concerns
We inspect PCBAs on a relatively hard ESD mat. Will moving the PCBs on the mat will scratch and stress the soldered components on the bottom side?

Should We Invest in 3D Optical Inspection?
Should We Invest in 3D Optical Inspection?
We are correcting many solder defects. The search for defects is taking too long. Should we go with a 3D AOI system to save inspection time? The Assembly Brothers, Jim Hall and Phil Zarrow, share their experiences and insight.
