coupon

Standard

ECSS-Q-ST-70-60C Corr.1

Definition

small piece of test circuitry that is used for quality conformance evaluation by specific tests and inspection

Notes

  • NOTE 1 The coupon is manufactured as part of a panel and at the final manufacturing stage it is separated from it. The coupon is thus associated with the PCBs within the panel, with which it was simultaneously manufactured.
  • NOTE 2 The term ‘coupon’ refers to a generic pattern, whereas the term ‘IST coupon’ refers to the specific IST pattern. [adapted from IPC-T-50M]
