. These residues are no longer impervious to the environment and pose a reliability problem with the product. Secondly, I’m not sure I fully understand how you are burning the flux as one would have to have an extra long dwell time when making a solder joint to burn the flux, which will definitely impact the laminate in

• Fluxless reflow utilizes gas phase Formic Acid (HCOOH) to replace standard fluxing agents • Eliminates the need for pre-reflow fluxing and post- reflow flux cleanup steps

. While the tempera- ture of the water in the heat exchanger does cause flux condensation, several systems now address this issue: Flux Burn-off. Certain ovens provide a periodic burn-off system that heats auto- matically to vaporize flux as it accumulates

. To remove the toxic and environmental hazardous byproducts, all gases leaving the oven are first passed into burn boxes located at the entrance and exit tunnels of the oven, as well as at the exhaust of the vacuum pump
