Home plate design is great for avoiding beads and tombstoning in some cases, but it will not help you when the spacing is too far apart. It will make it worse. You need a good even screen and accurate placement.

try to use stencil with "home plate" (arrow head) shapes of appertures for chips components. Any supplier of stencil can support you with this kind of design. janz

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

| I'm currently running a double sided paste smt board loaded with 0603's, on the secondary side. Many of the 0603 devices tombstone during reflow if the parts are not perfectly centered on the pads. Is this caused by the .008 foil thickness? Has any

There have been many designs of apertures for 0402, round, home plate, inverted home plate and various reduction amounts for square or rectangular apertures. What works best for a given application depends on PCB design, solder land finish, stencil t

Hello Bill, Ioan's idea's are good. One more thing that you may want to consider is using a "Home Plate" aperture on your stencil for the aforementioned caps. The idea is to put a smaller amount of solder paste directly underneath the component. This

Here's the picture!!! Not to say that people aren't correct that a home plate didn't correct their tombstoning problem (Is that enough negatives in one sentance to total obscure the meaning er what?), but it's not the first thing I'd change. Some o

Weare using a Home plate design on 1210 or larger, 20% reduction on pkgs from 1206 to 1210, 10% reduction on 1206 or smaller, 0 reduction on all leaded components(sot-23, IC's) with a 6 mil stencil. For fine pitch we are using 4mil stencils. We h
