  The Gravitational wave high-energy Electromagnetic Counterpart All-sky
Monitor (GECAM) satellite consists of two small satellites. Each GECAM payload
contains 25 gamma ray detectors (GRD) and 8 charged particle detectors (CPD).
GRD is the main detector which can detect gamma-rays and particles and localize
the Gamma-Ray Bursts (GRB),while CPD is used to help GRD to discriminate
gamma-ray bursts and charged particle bursts. The GRD makes use of lanthanum
bromide (LaBr3) crystal readout by SiPM. As the all available SiPM devices
belong to commercial grade, quality assurance tests need to be performed in
accordance with the aerospace specifications. In this paper, we present the
results of quality assurance tests, especially a detailed mechanism analysis of
failed devices during the development of GECAM. This paper also summarizes the
application experience of commercial-grade SiPM devices in aerospace payloads,
and provides suggestions for forthcoming SiPM space applications.
