Ralph Woodgate says that pump speed is the biggest driver to dross production

Hi, Can any one help me for how to reduce the dross formation in wave soldeing process , currently we are getting very heavy dross formation in process

Dross formation rates for SnCu and SAC are roughly 2.5 times the rate for SnPb (Hwang et al., 2004) Methods for reducing dross are: * Lower pot temperature * Run pump speed slower and only when soldering * Check solder contaminants to BS219, ASTM

HI, Can pl. provide the some detail on recomanded pump speed

Set pump speed so that the board is 1/3 to 1/2 immersed as it goes through the wave.

We installed a fixed distance optical sensor above the conveyor rail and "wired it" throught he machines terminal bus to cut the pump on only when a board was present at the pot. We also installed a timer in line so the pump would only stay on long e

Ralph Woodgate is the 'god of wave soldering process control.' We believe he is now retired, but in olden times his presentations at SMTA meetings were 'DO NOT MISS.' We imagine you can find his books on the used book market. Look here: http://use
