BGA assembly check by 2D X-Ray radiography after board repair - Short defect and balls size inhomogeneity
Industry :
Control techniques :
Radiographic exam of a BGA component board assembled after repair.
These radiographic images made by front view allow to observe a global inhomogeneity in the size of the balls, with for some, very small-sized balls.
The presence of many short-circuits between the BGA balls is also detected, revealing a problem BGA assembly on the PCB.
