Hybrid Technology Cost Reduction Improvement Study Program. Volume I. Results of Literature Search and Questionnaire Survey.

摘要

Hybrid microelectronic circuits continue to fulfill a growing need in military avionics systems where physical size (volume and weight) and performance requirements cannot be met by the more conventional packaging techniques such as discrete components on printed wiring boards, and where cost and schedules preclude the use of more advanced methods. The military market is generally characterized as fast turnaround, high reliability, and low to medium volume for any one circuit type. A system is usually composed of a large number of diverse circuit types with usage of only 100 to 2000 circuits per year. These moderate quantities, coupled with lower nonrecurring design cost and shorter development times, often make hybrids an economic choice over custom LSI/VLSI. The hybrid market is dynamic and growing making it difficult to arrive at an annual sales figure; further most major aerospace companies have captive hybrid microcircuit facilities serving their system needs. However, estimates of the total military hybrid market for FY 1978, based on data received from the questionnaire, is $250 to $300 million, assuming an average price range of $250 to $300 per circuit.
