Hi Lee,
I cannot concur with your advice.
Vibration: JESD22-B103-A Vibration, Variable Frequency
MIL-STD 883; Test Methods 2005.2, 2006.1, 2007.2
IMHO: these can make an excellent screening process for poorly soldered SJs,
but are not tests that either will prove or disprove product reliability.
Thermal Cycling: JESD22-A104-A Temperature Cycling
MIL-STD 883; Test Method 1010.7
IMHO: the latter document has never served the military very well as far as
SJ reliability is concerned--it is for this reason that programs like AVIP
were developed; the former is on a better track but has some technical
deficiencies, that is why IPC-9701 was developed.
