Flux Removal Method for Reflow Furnaces
SMTAI - 2020 - Described in this work, is a novel method of capture which separates flux from the recirculating furnace gas using an aqueous gas/liquid sequestration process. This system operates automatically and does not require production line shut-down for routine maintenance which consists of periodically emptying a small liquid waste container. This method is compatible with both Clean and No-Clean type fluxes. Capture efficiency of different fluxes were tested and will be reported in this study.
