When you say "....is there a way to easily (or at all) reference parts with the same specs..." do you mean when ordering stencils, or are you trying to drive your designers to choose a package that you already have in play when they have package opti

We make a custom mini stencil to print the paste onto the QFN and flip over to load on the rework station. The mini-stencil was designed for SRT to pick up the QFN. Check BeamOn (stencil house) for detail. Good luck

I am looking for recommendations for working with this package. We have ran some QFN20's but this one is a little smaller and lead-free. If anyone has experience with this, I welcome your comments. Thanks

I am printing solder paste directly onto a QFN device. Any recommendations on the type of solder paste to use? Namely I am concerned about getting a good release from the stencil. Thanks

The type of training I am looking for is things like micro BGA, flipchip, COB, new processes and techniques, ect. I already work with things like fine pitch QFP's, high mix double reflowed boards every day. I live in Vancouver, but I can drive to Sea

Is it this your first experience of C-CGA RWK ? In order to approach a RWK of this kind of pakage it requires a capable process and clear operating procedure. In the past, the company who I use to work for, we rwkd plenty of this kind of CCGA. Earl

From what I know, you should follow IPC standard for the class assembly that you are building. From your post somebody mentioned something somewhere - doesn't make it official information. I would not be worried about having voids, but what is their
