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

For process management with SPC of the stencil printing process with a fully automatic stencil printer, what process outpur parameter would you recommend for SPC? It appears to me that there are two options: A: to have a pn chart based upon the % of

As has already been suggested, make sure you are cleaning your stencil well between long periods of inactivity. That said, it sounds to me like you have a feeder problem to solve before you get too wrapped up in what to do with your printing process

My input are: i. To solve tape not pulling back if it is due to high per is better to use more feeders to minimize this issue. ii. To slow down printing speed. Hence, has proper line balancing which minimize board idling before pick and place process

My printer handles 1500mm stencil, so no, 4 ft boards print ok. If you are bending the board for the oven, does that mean your printer and PnP handle the full length?

Solder paste has stencil life time - if you go over it means you should change it. If you print boards in front and keep them for too long before reflow, the flux is still evaporating, so you are not mitigating the risk. Paste also likes room tempera

Hello Sanjay! The cheap deal I use that Earl spoke of is called a SMarT Measure. It's a depth measuring microscope that uses the same principle of measuring optical focus that the units from Vision Engineering do ( if you've ever looked at any
