yeah, we use the low static stuff too... except when the purchasing assistant did the company a "favor" and sought out something cheaper. Those times you want a big stick! The color confusion is because of the rose colored glasses that I wear. Joh

Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean sock

We produce a board right now with a QFP that has 20 mil pitch and we are seeing problems with the solder deposition. I believe it to be a cleaning issue which we are addressing. Soon we will be pasting for bga's. Is there a problem with using inter

Manncorps MC110 is AUTOTRONIK BS110, just sold on Manncorps name. We are using same printer for 3 years. Frame holder will brake soon, when using 29"X29" holder. But you just need to add U profile on holder (for strength)and fix it with few bolts. A

We have had some success printing 20mil pitch with our IIT Proframe. It takes some babysitting, and you don't want your operators to be changing these things out every hour or you'll be buying lots of them. Pulling tension in one direction gives r

There are two primary causes of epoxy adhesive bond failure, heat and over exposure to moisture. Ultrasonic cavitation is a only a mechanical "scrubbing" action on a microscopic level. However, if the adhesive bond is week or has small areas of det

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

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
