Good evening, I do. 2mil overprint is not critical. Paste will simply flow back. Paste flows back even with larger overprint (up to 15mil at least). 5mil stencil thickness if fine also. BGA area ratio for both BGAs is higher than 0.66 required by IP

I am attempting to reball some PBGA's with no luck. The problem is getting the solder spheres to sit in the stencil apertures and removing excess spheres. I apply light amount of flux to pads of a BGA, align a stencil over a BGA, then pour solder s

Hi: If anyone have the experience with the PCB pad design and stencil design for the uBGA? We meet the problem for it. The component data is 0.3mm diameter and 0.5 pitch. Could anyone tell me the PCB pad dimension, the stencil type and aperture dimes

Dear davef, All of this are takling about how to improve release solder paste, Area ratio, aspect ratio...etc, but i want to learn the "When design BGA stencil which the safe air gap between solder paste in difference stencil thickness", this can he

Hi All, Just a quick question in relation to BGA Stencil Aperture Design - We currently use 1:1 ratio - are there any rules or benefits from over printing the PCB Pad ? Replies appreciated. aj...
