Sanjay: Keys to successful adhesive printing are: 1. Understanding the flow behavior of the adhesive under constant shear stress 2. Stencil design, i.e. stencil aperture opening 3. PWB Footprint 4. Stencil printing parameters Optimizing all these fac

Whoa! I beg to differ my friend. The cure profile is VERY critical in Adhesive curing, especially if your are screen printing. When you screen print adhesive you are leaving it exposed to the atmosphere for a period of time. SMT adhesive by nature i

Hey Guys, Thanks for the input and suggestions. Just been onto the adhesive manufacturer who reckons they should be no issue using a reflow profile for curing his adhesive , as long as the profile duration is not 6 minutes or over, which would bake

I know it's been brought up a thousand times before but after an hour of searching the archives I'm taking a short-cut. When processing one side of a double-sided assembly with adhesive, should the adhesive side be processed first or should "side" c

I am evaluating a bottom side glueing process. I was wondering if anyone could share their shear force specifications, or how they were developed. I would be most interested in the 0805 and Sot23 package types. Also, does anyone know if heating th

Hi There, Could anyone please give me some pointers on screen printing non-conductive adhesives or where I could find the information avaliable. Aspects such as printing parameters, ideal stencil design and a general overview. Do already have a part
