Kapton tape is anti-static, that's why we use it so much in this industry. If you are seeing yellow light, either whatever you are pulling ain't Kapton, your Viagra is stale or whatever you had for lunch, I want a double!

I typically use kapton tape when I need to mask off some apertures.

second the kapton tape. Another tape we use alot of is powder coat tape (a tan color) because it has excellent heat resistance and a good adhesive that does not leave residue.

What the heck are you doing having scotch tape in the plant? Isn't there a concern for ESD safety? Ban the scotch tape, then they won't have something to block the apertures with.

One thing everyone missed is what is the goal of the company. To make money!!! So how many boards per week are you shipping now and how many would you be shipping if you had seperate stencils or a DISPENSER. With quality being number one always the

Why not quantify the amount of time spent taping apertures every time you want to use the stencil vs. the cost of a new stencil (about $300, usually)? Look for problems that are created by the blocked aperture method - is there rework down the line t

Something you'll want to consider is what happens with bits of tape that become relocated due to manual or automatic wiping. I've seen them block fine pitch apertures and create an insufficient solder condition that, guess what, wound up in the hand

I recently started at a new company. They have a variety of bare PCB's and most have aprox. 20 variations. Maybe about 1/3 of each board on average are non-populated locations. They buy one stencil for each PCB but then use scotch tape to block of

Stephen, I don't understand this at all mate. 1. If you don't place a QFP and get bridging across the bare pads, you were gonna get absolutely horrendous bridging if you did put one down. That points to poor printer set up or stencil design or both

actually the "yellow lite" part of my posting was simply spoofing Dave's light up band-aid wrappers. But seriously (again) most high temperature Kapton polyimide film tapes, like 3M #92 and #1205, develop a considerable charge when unrolled or remov
