Stencil Design

2017/2/28 18:29:42

Hello there,

I have a new board, fairly heavily populated with a number of FPBGA on it. The smallest has a pitch of .4mm.I have 3 questions, 1st what is the best appeture for this small pitch. 2 Will type 3 paste work or will I need type 4, and finally what will my stencil thickness be. We usually run around 5thou but I think this might even be too thick. Electroform is the way for the stencil but not sure of the thickness
