Beschreibung
Zusammenfassung:	microelectronic engineering. SUBSTANCE: totally sealed microelectronic unit used for electric circuits of radio electronic devices distinguished by functionally nonuniform composition and intricate morphology of interconnections of parts and circuit components has case divided by means of partitions into compartments, cover soldered to case over its perimeter, sealing assembly, and stuffing arrangements. Case is monolithic structure built integral with partitions; its area as viewed on top is at least 100 sq. cm. Degree of sealing with respect to helium leakage is between cm2 and 10-4 to 10-3 l Pa/s. Partitions have bulges that function as stops for additional case-to-cover fixation by compound-sealed screws. Cover underside depressions made at cover-to-partitions mating points accommodate contact springs. EFFECT: improved reliability at high integration of large structural levels of devices. 8 cl, 5 dwg
