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.

We have been pretty successful with screen printing glue, however the smallest component we now glue is a 0805. We had many problems using our Gemini II to put down glue dots for a 0603, so we altered the pads to do double-side reflow. As our own int

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

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

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

Lachrymal, Where are you getting that from. Let me keep this simple because there can be so many variables in modern printing, some you can control and some you can't. Unless you are designing your own PCB's where you can decide how to orient the co

If I understand customer's intention correctly, it would be fastest, mass production with fully utilizing the Pick-N-Place machine capacity with minimum manual labor which won't break the bank. They used to manual hand soldering the coil to the boar
