Manufacturers in this category

Quality process, mapped to industry standards

  1. Source verification — supplier credentials, lot origin declaration, authorized-chain records (AS6081)
  2. Incoming visual inspection — markings, coplanarity, oxidation, refurbishment signs (IDEA-STD-1010-B)
  3. X-ray — die, bond wires and voids compared with a golden sample (AS6171/4)
  4. Decap / solvent test — sample decapsulation for die marking; acetone marking test (IDEA-STD-1010-B)
  5. Functional / electrical test — key parameters on bench or at a third-party lab (AS6171/6)
  6. Moisture & packaging — MSL level, vacuum bag, desiccant, humidity indicator (JEDEC J-STD-020 / J-STD-033)
  7. Shipment report — inspection photos and report number with every lot (ISO 9001:2015)
