Spoilit... and Phil, it is your regular 29" frame, but it is thinner - 13mm is what I measured. For your vendor this is cheaper as they give you less metal, so usually these have lower price. I assume all stencil vendors will have it nowadays. No ne

Michael, Good afternoon. My experience with the frameless stencils has been less than optimal. I tried the universal stencil system about a year ago and these are my experiences. 1) The stencil manufacturer supplied me with a free frame to try ou

I dont know what kind of screener you use but my 1st impression is that the board and stencil are separating too fast,the paste doesn't have enough surface tension to stay on the board, you're tearing the paste off the board. If you can, slow down th

What sort of foils are you talking about? Handling VG stencils isn't exactly tough, they're a bit more flexible than standard tube frame, but nothing horrible. Pair it with a good storage solution and you're set. I'm able to store 165 stencils i

Hello, I'm doing some research on frameless stencils/stencil frames and I'm looking for people's thoughts on them. I'm looking for any and all thoughts/opinions on how well they work or don't work. Some specific areas of interest: tensioning in one

Hi Dave I have used the IIT proframe II (I believe the proframe I used four sided tensioning, was somewhat inconvenient to set up and is obsolete) for about six months. I don't have any complaints of note and I do use it to 20 mil. It does take som

Por, You talking wave solder or reflow solder? At wave, nitrogen is the way to go. Just like you stated, it does affect the surface tension. If you're reflowing, I wouldn't go nitrogen unless you have to. Improper stencil design is usually the c

I've always been a big fan of the VectorGuard frame system, especially in high mix environments as it saves a ton of space in your shop storing stencils. Maintenance hasn't been a big issue for me in the past, just keep spares on hand if it's a conc

Phil from the picture attached you see the challenge - there is no marking to show you which stencil is what. That is why people keep it in a box- to be able to see the number. I used VG for long years and I never liked them. Also with high changeove

The purpose is explained in the program 'help' - 'contents' menu. Due to viscosity and adhesion of different fluxes, paste may stick to the stencil more than the board. Using steps allows the surface tension and gravity to pull the paste down; rather
