Is the board coated, some coatings can crack solder joints?
Check your pad geometry and reflow profile?

Hello,
Our customer's product is to be used in aeroplane. It has lot of
Leadless Chip Carrier (LCC) package IC. The LCC's solder joint
cracked during the FCC vibration and thermal test. Could anyone have
experience with similiar problem share it with me? We are currently
looking looking into 2 different solutions:
1. PCB finish plating and solder paste.
2. Converting LCC to leaded package.
Other suggestions are deeply appeciated
Regards
Steve Siu
