I need a good laugh!
I have pulled chips from commercial equipment that has a cermaic case, it is good for heat dissipation.
A fewl facts about military equipment. The chips are never socketed! Apply 1 G of force and you have many chips loose inside the case. The PCBs will have heat guides/strips to cool the system and strengthen the PCB. You can not bend a high rel PCB.
What is the fascination with military chips?
Most military parts are very old (but tried and tested) technology.
Until the next time. :-P
