Hi, I'm having a lot of problems with BGA's shorts, we are using 0.005" stencil aperture 1 to 1 (0.014)", the paste is centre (I can not measured the height)was verified using electronic microscopie, the placement is centre (I'm using local fiducials), the profile is 215 peak and around 65sec above 183 grades C. The assembly has 4 BGA's (the same component) located one behind another one and the shorts are random. I appreciate any suggestion or input.
