Hybrid Microcircuit Rework Procedures Evaluation.
Abstract
The objective of this program is to make a comprehensive assessment of all factors related to the rework of hybrid microcircuits and how these factors affect hybrid reliability. Based on this assessment, rework, criteria and guidelines have been prepared for inclusion in MIL-M-38510. The program effort consisted of two major tasks: (1) A review of the hybrid microcircuit literature and a survey of 21 manufacturers of military grade hybrids, to determine the common practices and in-process controls used and problems encountered in hybrid manufacturing. (2) An experimental evaluation of the reliability of reworked vs non-reworked test specimen hybrids. The test phase of the program utilized the effects of mechanical and thermal stresses, applied as conventional MIL-STD-883 environmental test exposure, to measure the effects of one, two or more rework cycles on wire bond degradation or failure.
