Yep, only the MLF have this blowhole/pinhole issue. Other components like SOT(transistor), CAP, RES are hey-o-kie. Btw, MLF = micro lead frame (IC/LGA) package. looks like a BGA without the solder balls. has direct attachment to the PCB ENIG pads wi

Hi, We were running with few defects with lead solder paste. The lead solder paste with stencil 0.010" X 0.020" and 0.004" thick stencil produced near defect free PCB assys. 0.010" X 0.020" (0.004" thick) lead = defect free 0.010" X 0.020" (0.005"

How wide are your pads? What paste are you using? What is your board finish? Could you please post a link to the datasheet for the component? We place a lot of MLFs, both in a Pb and Pb-free process. Our standard stencil design for MLF compon
