High-value and high-volume ICs (MCUs, power ICs, memory) attract remarking, recycling and cloning. Obsolete and military-grade parts are especially targeted.
Check laser marking quality, font, batch code consistency, package surface, lead finish and mold flash. Compare against official photos. Date codes should be consistent within a reel.
Functional tests catch wrong silicon; X-ray reveals die differences; decapsulation verifies the die. For high-risk parts, combine 100% electrical test with sampling X-ray.
Buy from distributors with traceable channels, original packaging and quality records. HuaXinGou provides batch codes and supports inspection before shipping for high-risk parts.
