Quantitive Dross Remover Evaluation
 One LF wave pot and one Pb wave pot in Bu6 and Bu3 respectively were selected to do evaluation on real production line.
Evaluation step:
Remove all solder dross in the wave pot
Add around 350ml dross remover to the pot surface to form a thin layer
In producing, add 100~200 ml every 3~4hours to prevent dross generation(no product, no need to add and just need to monitor and add 50ml to keep the layer on the surface on pot
Record liquid consumption and dross quantity every day until the dross remover used up
