Why is Visual Inspection important?

External Visual Inspections - External Visual inspection is to detect validity of logo, part number, lot code, date code, and /or PB-free marking; marking technique; quality of marking; mold cavities; straightness, coplanarity, scratches, bridging or other defects in terminations; surface texture.

Internal Visual Inspection X-RAY- is a process used to verify the internal attributes of parts such as dimension, alignment, anomalies such as missing or damaged bond wires, missing die, and presence of foreign particles.

Decapsulation (Internal Visual) - Decapsulation is the process that provides essential information about die such as Logo, Mask set, Part number, and Copyright year. These attributes help to determine if components may be counterfeit. This is a destructive test.

XRF Test – X-ray Fluorescence Inspection (XRF) is performed on the leads to confirm whether the material composition of the finish on the leads has lead or is lead-free. This method is used to determine if parts are ROHS compliant or not.
