We've had our My500 for about four months now, and couldn't be happier. We are a super-high-mix, super-low-volume shop, and the flexibility provided by the 500 over stencils is stunning. So, you buy 5-10 stencils a week? That's 260-520 stencils a

Robert, Here's my recommendation's: Solder paste opening on screen should equal the solder mask opening on board. Stencil thickness at .008" but this should not be your main concern as stencil thickness should be determined by the fine pitch that ar

Dear Masdi, Perhaps you should check again your screen print process. Small amounts of solder paste under stencil can cause your problems. This paste is from previous printed pcb. When printing next pcb this paste attachs to places that it doesn't

Dave- this may not be much current help but for future needs: IPC-7525 Stencil Design Guidelines is due out real soon. Check with IPC on its status, last I heard it was in interim Final.What is nice about this Doccument is that it also covers Pin_Thr

We are using Austin American Technologies with Petroferm solutions and have excellent results using the same two types of solvents for cleaning stencils, adhesives and miss print boards. I average about five hundred cleaning cycles before we have the

Hi Maybe you have too small apertures in stencil. Good apertures size is 90% from pad. And one thing what you can try is that you cut your stencils(blades) aperture corners round (i mean like a oval). I hope that these advices can help you.

Dave, George I think we're missing something here, or at least I am. While the plastic in question could possibly be dissipative or non generating, I'm wondering how thick such a stencil would be to clear even the lowest profile PTH component? Can w

John, Dave. The adhesive deposition is on the second pass through the SMT area, the PTH components have previously been fitted during the axial / radial stages of manufacture. The stencil is 2mm thick with a 1.5 mm routing depth. the leads (cut & cl

Have you thought about stencils for glue? We stencil all glue boards quite succesfully. No CAD no clogged nozzles, much faster speed aperture designs are fun to work with. Just a thought for an alternative. All the companies mentioned also will advis

Bill, I would assume that the stencil rests on the soldermask especially when you use a metallblade. If you know the difference in height between soldermask and land you could take that into your volume calculation when figuring out your desired ste
