x-ray inspection

brief introduction:

x - ray is using a cathode ray tube to produce high energy electron striking a metal target. in the process of impact, because of the sudden slowdown of electronic, the loss of kinetic energy will be released in the form of x - ray.

purposes:

to test the internal cracks and defects of foreign body in metal materials and parts, plastic materials and parts, electronic components, electronic components, led components; analyze the internal displacement in bga and circuit boards; distinguish bga welding defects such as empty welding, pseudo welding; analyze the internal situation of microelectronic systems and rubber seal components, cables, fittings, plastic pieces etc.

applications:

ic, bga, pcb/pcba, and surface-mount technology weldability test etc.

reference standard:

ipc-a-610 ,gjb 548b

typical test images:

bga voids	bga tin ball cracking
pcb line disconnection	check the ic defect
