vshan, Good Morning. I used to work for a flex house and was responsible for the SMT assembly area. What is your question? Thanks Chris

1" long SMT components to be placed without coplanarity issues> Also, what types of finishes are common for the flex;i.e, ENIG, immersion Ag, etc.?

Hi Vshan, Have more pallets made, and don't stack them - lay them flat on a trolley and move them back to the start of the line.

PPM is a good place to start. They've always been good to us. www.goppm.com

I actually think PPM bought the quad name/rights from Tyco. Have not dealt with them much but experience I do have was great, seem like great guys.

They are all compatible with each other. Data is at alpha metals website and FCT assembly Russ

Russ is correct. We have been using SAC 305 for SMT and SN100C for wave and selective and repair for about a year. May switch to SN100C in SMT at some point if we can get some paste that wets better.

We have been using SAC 305 for reflow and Cobalt 995 (very similar to SN100C, only cheaper) for wave and rework for quite a while now with no issues that I'm aware of.
