Nomorely the V-shape home-plated apertures look like two opening mouth facing each other. But this time just opposite way. And make 30% home-plated. Hope you can understand.

I think Real Chunks has your answer home plat or reverse home plate or like we use a 10% reduction on most aptures vs pad I think your problem is to much paste on the pads we used to see a lot of that with 8mil stencil thicknes on our 1206 caps went

:On a dense board, a great way to reduce solderballing is to either; print paste 1:1 with pad size using a 5mil foil, reduce aperture openings by 10% of pad size or change aperture shape to "Home Plate" design. If none of these work on their own you

You might want to try reducing your stencil aperture by 10% first off; if it still swims try using a home plate design. Also if your profile is going into liquidous to fast, this might cause the swimming as well, check your profile.

Any recommendation to reduce solder beads next to 0402, 0603 and 0805 caps and res? What about home plate vs. bow tie stencil aperture design?

Commonly when we see solder balling, we think "too much paste." As a result, we pinch the apertures or change the shape to a "home plate." We don't think that's what's going on here. But what if this component has a thicker solder plating on its ter

Where did you find this article about "U-shape" apertures? I believe it is simply talking about rounded corners on the inside of a normal square aperture. ( resembling a filled in U ). It kinda follows the same ideas behind the home-plate design, wit

That reminds me...We already have home plate apertures on our stencil. Try number 2...I tried an overall reduction based on the copper layer of 10% and used oval apertures. I hope that you guys can suggest something that I am over looking. I know tha

I found solderballs are around chip components (on one side of middle area), I checked gerber data, solder paste of aperture on the stencil for these chip components have 5% reduction to solder land on PCB, shape of solder land are square, not home p
