Can you please tell us which components cracked? Component type, size, pitch, pin Qty, etc. The solder cracked in thermal cycling is very complicated and difficult to solve.

You may check with the TDS of respective "active parts" IC manufacturers for their recommended no. of thermal cycles permissible in the reflow process. Last I checked 3 cycles for our RF-apps IC was still allowed. For 48pin-QFPs this can be allowed

BGA Thermal Cycling Tests?

We are looking for recommendations on reliability testing (thermal cycling, vibration, etc.) of BGAs AFTER being soldered to a PCB. Are there any standards that include such things as heating cycles (like a minimum of 5,000 cycles), ball-ball leakag

depends on what you want evaluated! you can thermal cycle the BGAs and the examine the x-sections to determine failure modes at different stages of thermal cycles. you can do a stress test and corelate the # of thermal cycles with the microstructu

We experienced brittle solder joints that did not withstand thermal cycling as I was told. I am positive about the fractured joints but was informed by customer that it was thermal cycling of the part when they failed so they were latent failures.
