The environment essentially defines the need for coating. "Inside" may mean inside a men's locker room with attendant high humidity or inside a climate-controlled clean environment. Conformal coatings offer protection against moisture, fungus, chemi

I've been wondering if I was the only person thinking this. There are so many print parameters that are programmable now on new machines (squeegee pressure, height, speed, snap-off settings, cleaning intervals) that the process would (in my oh-so-hu

Didn't you hear? Fendelaz went out of business and sold the rights to the Magnaplancil to Amahlmahay. Sure, all the standard variables still affect the print quality (aka registration and volume) but if the machine controls everything but paste di

I don't think the syringe pressure has been adjusted, but I'll watch over the next few days to see if it changes (by itself of course). We don't control the humidity in our plant and don't really track it. However, there have been some significant

Dear Keith. A vertical lift of stencil or vertical lowering of the PCB is best way to control the separation speed which is essential in fine pitch printing. The clamsheel lifting will give a different separations speed depending on the distance fro

Hi mates, anyone done SMT process for micro-lead frame (flip-chip)before? Appreciate any process control caution points from the experienced guys (yonder the deep blue seas) who have done this product before. 1) pcb thickness 2) pitch-to-pitch (co
