Genny you are right on with the differences between suppliers/packaging etc... I am a CEM and you are correct that we pay no heed to cad rotations from our customers/designers. A.V.L./manufacturers P/Ns information specifies orientations and such.

First I would have your solder bath analyzed by a certified lab. Secondly I would get an analysis from each supplier that you are speaking with on their solder bar. The lowest price does not necessarily mean the best product and vice versa. Alot of p

I experienced this with a high-mass capacitor. I was able to turn down the bottom-side convection (around 50�C lower than each of the top-side heaters), and able to NOT lose any parts. I got the bottom-side part just slightly over liquidus, and min
