Solder Paste Inspection - When and Why
Solder Paste Inspection - When and Why
Folks at our facility are pushing us to purchase a 3D solder paste inspection system. Are these systems common and under what condition should we consider buying one? Phil Zarrow and Jim Hall, the Assembly Brothers, provide insight.
