So are the foils cut by the same adapter people? I'd like to use existing foils if possible and have them notched to fit someones Adapter.

I am looking for a nice storage rack for foil type stencils, not the frame type. Some thing compact yet easy to work with. Any directions/advice. Thanks in advance.

What foil thickness? Type 3 or 4 paste? Have you checked your area ratio(s)? You could overprint or drop your foil thickness by one mil to improve the ratio and paste transfer. As always you can search the fine SMTnet archives for more info.

Most boards are fabricated with 1-ounce copper [34.79µm (micron/micrometer)]. Foil more commonly comes in at 33µm or less. Processing reduces this down to 30µm or thinner. Talk to your board fab about the specifics of your application

We have a few Bliss racks. They were made for 29x29 frames but we use them for vectorgaurd and foil. DEK ships vectorgaurd stencils in a nice, thin cardboard box. We use these boxes for storing vectorgaurd + foils. You can store a handful of foil

Steve: There are guidelines for determining if your aperture has the correct proportions to the foil thickness. Maybe that�s what you�re looking for: 1 Aspect ratio = aperture width/foil thickness Chemically etched SB GT 1.5 Laser cut SB GT 1.2

: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
