My company is using HEPA filter to improve air quality coming out of oven/wave solder. But the cost of such filter is quite high and we need to improve the consumption. Any suggestion from fellow experts out there?
a. Anybody did a cost reduction project on HEPA filter with good air quality out? Can share with me. b. Anybody use pre-filter? Can suggest any? c. In terms of process, what can be reduce (flux?) to improve the air quality? Any suggestions?
