Conductive Adhesives and Underfill used on flex ckt

Electronics Forum | Mon Jan 11 20:26:54 EST 1999 | Chris G.

I have used conductive adhesives for some time now on thickfilm. Does anyone know of a really good conductive adhesive to attach flip chips to flex circuits? I would like to stencil print the adhesive to the substrate and then place the flips chips

Quick Frame and Dek 265GS

Electronics Forum | Wed May 20 07:13:15 EDT 1998 | smd

Does anyone use the "Quick Frame" with their Dek printer? The threads on the screws keep stripping, so we thought maybe we'd send our frames to a machine shop for heftier screws. Has anyone done this? Is there a better way? Isn't it weird how Alpha k

Before risking screwing up the alignment of the frame, and upon the advice of several SMTNET users, I decided to see if I could get away W. just changing the screws. I found screws with 2x the pull strength as Alpha's. But they didn't fit!! The Alph

Tape and shunts are good ideas for WS *BUT*...

Right now we are taping the goldfingers which is effective but also expensive. Also, some tape was leaving yellow marks on the goldfingers. We're trying the so-called goldfinger glove from Steven's Products. It's a very small company (probably one gu

What's Best: D Pace, Simplimatic, or Lynx?

We're getting new SMT equipment! A flex machine and conveyors to boot. We have Simplimatic equipment now but I'm wondering about Lynx (I have the strong impression that Philips wants to deal) or this D-pace company? What's the 411 on these guys? Equ

What's the Deal W. Philips Topaz??

Electronics Forum | Mon Jun 08 07:49:40 EDT 1998 | smd

In our continued search for another flex machine, we reconsidered Philips Emerald (low Vol/high mix Mfg). We already have a CSM so it makes a little sense. Then the salesman started talking about the Topaz. The Topaz supposedly is "practically the sa
