5mil works great. Just make sure that you screen alignment is dead on. We're using a SAC305 with a home plate design. I ran a test a couple of months back and found that the home plate design works the best with 0402s.

I have to agree with Dave here. Can you compare the datasheet pad recommendations to your design ? It may help to show the forum a picture of the bare PCB pad design along with a pic of the bottom terminations on the part. What Stencil thickness a

Thanks for your response. I am reducing the stencil opening and ensuring no solder paste deposited at the cornor of the pad. Not moving to homeplate design considering the component size. Will share the exact design.

Hi Todd, it might be a philosophical question if soldermask between finepitch pads is prefered or not. That should depend on the capabilities of a particular site and their experience. We actually prefer soldermask down to 0,4mm pitch and don�t have

I like AIM solder paste, personally. But, much like asking which pick and place machine is best on this board, you're likely to get as many opinions as there are paste manufacturers. I just took a look at Alpha's datasheet for this product, and it

Could be. I am making overprint to achieve proper amount of solder paste inside hole. Now I am trying to reduce maximum overprint and compensate it with step - up stencil. This could reduce effect that some particles of solder paste are not gathering

Hi All, We just started build a new product and I am encountering many non-wet rejects in our new product. I need help on what should I look into to improve our Yield. Please see below back ground 1. We are using DEK Infinity as printer. 2. We are mo
