We are having problems wave soldering SOT's located on the bottom 
side of the boards. The SOT's have insufficient or no solder after 
waving. I have several questions reagarding this problem.
1. Is there a recommended wave profile?
2. Is there a recommended pad geometry for SOT's?
3. Is there a recommened flux?
4. Does anyone have any reports or technical articles on this issue?
Thank You,
Tom Rapp
