In a former life (Commercial Avionics/Military Avionics) we tried using
LCCC's with miserable results. We used them on FR4 and Teflon PCB's.
After only several hundred temperature cycles (-55C to 85C @ < 5C/min), the
solder joints would crack. We stopped using them as fast as we could get
new parts spec'ed and PCB's relayed out for compliant pin packages.

Greetings,
Is anybody out there using
leadless ceramic chip carriers in a military environment without attaching
leads? If so, what size are you using?
Thanks in advance for
any information,
