Abstract:

The objective of this program was to develop the material and process data necessary for qualification, acceptance, processing and control of selected solvent soluble coatings for particle immobilization in monolithic and hybrid microcircuits. These coatings are removable by a hands off procedure simplifying and reducing the costs of rework encountered with nonsoluble coatings. Qualification testing included a screen test and operating life test sequence using coated production hybrid microcircuits 32 microcircuitscoating comparable to that required for MIL-STD-883 Class B microcircuits. Based on the results of the data obtained, material and process specifications were prepared covering two types of coating materials. The Type I material covers block copolymers of dimethylsiloxane and alpha-methylstyrene. The Type II material is a block copolymer of vinylidene fluoride and chlorotrifluoroethylene. Author
