I received data sheets from a paste distributor in which Amtech gives a recipe how you can mix solder cream. They deliver the flux in plastic jars and the solderpowder in foil packages. You must mix the two components with a simple mixing tool. Has a

We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes?

Has anyone had trouble waving and gluing 0603 R's and C's? At my company, our designers have "opened the floodgates" on bottom-side 0603's. We've got an EPK+ with rotary chip and omega wave but can't seem to get skip-free soldering on these guys.

Thanks for all replying to my printing SPC posting. I like to expand the SPC discussion on reflow and wave soldering. I am aware of the common methods of applying periodic measurements using test vehicles though the machines to collect critical pr

1) For solder short, pls check the paste height. Too much vol will cause short. For 15 mils use 5 mils thickness stencil if possible. Check profile preheat time to prevent hot slumpof the paste. 2) type 4 powder will be better for 15 mils pit

As the traqnsistion to Pb free manufacturing gains speed and exposure the period between true Pb free solutions and the present is still somewhat distant. Are there any publications or documentation on the use of Pb free components and non-Pb free

Hi, We are in the process of transitioning to LF production. What are some of board materials being successfully used in production? Also, what surface finishes show promice of good results with SAC 305 solder? We are currently testing multiple boar

We use nothing but silicones and have for at least the last 7 years. We don't have relays, but we do have motors. No issues with soldering, but our lines are constructed such that the last solder operation is a good distance from the coating or pot
