In the experiments that we have done on wave soldering the omega wave has 
shown little significance in the reduction of solder defects.  The main 
factors that have stood out to us are 1. the spray fluxer nozzel size, 2. 
spray fluxer pressure, 3. conveyor angle, 4. topside board temperature, 5. 
solder bath temperature  6. turbulent wave, 7. dwell time.

I have seen the omega wave help reduce out gassing but I have no data to 
back that up.

GREETING FORM BLUE SMURF

Question:
What is the main function(s) of "OMEGA wave" in wave soldering?

A.   Eliminate excessive solder,
B.   Product extra thrust in the entrance region,
C.   Reduce air trapped under board
D.   All of the above
E.   Other

Question:
Is there any paper, data, or DOE outthere to backup these findings?

Thanks for your response
