Dear Experts, Have any paper or data talking about the design guideline for avoiding BGA solder bridge? I desire to know the rule(guideline)that compare difference stencil thickness and safe solder design distance (air gap) can avoid bridge.

I'm no expert but I think you will find the majority of discussions around BGA & good printing results focus on the PCB design and things like tented vias and pad definition. e.g https://macrofab.com/blog/bga-pad-creation-smd-nsmd/ After that, work

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

You have lost me, its a stencil, you can change the aperture size, you can change the thickness and you can change the walls of the aperture. And all of those things will be in the papers anyone can find with a google. I have no clue what safe air g

Air gap on the PCB is determined the pad spacing which in turn is governed by the component. As long as the PCB designer is following the typical BGA layout best practices; i.e no open via in pad, non-solder mask defined pads, solder mask covered tra

Now I urgently need the standard of IPC-2252 Design guideline for RF/Microwave PCBs, Who can help me? By the way,who can recommend some DFM experts on RF PCB design?look forward to your responding.thank you!
