APPENDIX A
A.4.8.1.1.10 Failure and defect analysis and feedback. The procedures for identification, handling, and analysis of
failed or defective devices and for dissemination of analysis data shall be documented, including the procedure for
informing the qualifying activity of analysis results, when applicable.
A.4.8.1.1.11 Corrective action and evaluation. The procedure and responsibility for decisions regarding the
necessity for corrective action as a result of failure or defect analysis, and for evaluation and approval of proposed
corrective actions, shall be documented. If the procedure for evaluation and approval of changes proposed for other
reasons, such as cost reduction or product improvement, differs from the above, it shall also be documented.
A.4.8.1.1.12 Incoming, in-process, and outgoing inventory control. The methods and procedures shall be
documented which are used to control storage and handling of incoming materials, work in-process, and warehoused
and outgoing product in order to (a) achieve such factors as age control of limited-life materials; and (b) prevent
inadvertent mixing of conforming and nonconforming materials, work, or finished product. Tests and inspections
performed by the manufacturers on acquired materials and supplies shall include verification of chemical, physical,
and functional characteristics required by manufacturer drawings and specifications. Procedures shall be prepared
and maintained for controlling the receipt of acquired materials and supplies. The procedures shall provide the
following:
a. Withholding received materials or supplies from use pending completion of the required inspection or tests, or
the receipt of necessary reports.
b. Segregation and identification of nonconforming materials and supplies from conforming materials and
supplies and removal of nonconforming subassemblies and parts.
c. Identification and control of limited-life materials and supplies.
d. Identification and control of raw materials.
e. Assurance that the required test reports, certification, etc., have been received.
f. Clear identification of materials released from receiving inspection and test to clearly indicate acceptance or
rejection status of material pending review action.
A.4.8.1.1.13 Schematics. Schematics pertaining to the testing of microcircuits shall be under document control.
This includes device schematics or burn-in schematics in accordance with the applicable device specification or
drawing.
A.4.8.1.1.14 ESD handling control program. The ESD handling control program documentation shall be under
document control. This includes methods, equipment and materials, training, packaging, handling, and procedures
for handling ESD sensitive devices.
A.4.8.1.2 Records to be maintained. The records required by this section shall be continuously maintained during
the manufacture of microcircuits that are intended to be submitted for quality conformance inspection under this
specification. The records pertaining to production processes, incoming and in-process inspections shall be retained
as detailed in A.4.8.1.2.b. Those pertaining to screening and quality conformance inspection shall be retained for a
minimum of 5 years after performance of the inspections. Records shall be maintained as a minimum for:
a. Personnel training and testing (see A.4.8.1.2.1) (1-year active file retention; 5-year total record retention).
b. Inspection operations (see A.4.8.1.2.2) (1-year record retention for production processes, incoming and
in-process; 5-year record retention for screening, qualification, and quality conformance inspection).
c. Failure and defect reports and analyses (see A.4.8.1.2.3) (5-year record retention).
