X-ray non-destructive tester battery industry application

LED semiconductor industry analysis and application range:

LED chip, LED internal bonding line, LED crystal line, LED wafer, copper column and other detection diodes, three-stage tube, capacitor connector, etc.

LED process defect introduction

(1) IC chip, diode hole, bubble. Cause: Less tin furnace temperature solder paste stirring

(2) LED internal binding line, LED crystal line IC package, judge: whether the line is off, the angle of the line



(3) Discrimination of other defects: internal detection of capacitors, wafers, and connectors
