BGA, stress on the PCB

2017/2/2 1:10:40

I've a problem with a BGA. I've the impression that the balls broke then there is a too big mecanical stress on the PCB. I lost some dBm and when I press on the BGA I measure the good value! It's like the balls are take off the BGA or PCB and when you press on it the balls paste to the BGA or PCB.
