How ZDI inspects latches

  • Lot-level visual inspection under magnification: markings, date and lot codes, body finish, lead or termination condition
  • Packaging and labels checked against the maker's format; moisture-sensitive parts kept in MSL control (J-STD-033)
  • Counterfeit-avoidance steps based on AS6081 and AS5553, with X-ray and further tests escalated by risk
  • Inspection photos and an EQP report available to customers in My ZDI

Our inspection process follows AS6081 counterfeit-avoidance practice. See Quality & AS6081.
