1936MK5-F Formic Reflow Ovens

Fluxless/Formic Reflow Ovens

Heller has designed and built a production ready horizontal Flux-Free Formic Reflow oven forformic acid vapor soldering. This new oven has been designed to meet Semi S2/S8 safety standards(including toxic gases).

Our Formic Reflow Process

These formic reflow ovens operate like a normal reflow oven with the addition of formic acid vapor injectioninto key thermal zones (typically soak zones). Here the formic acid removes any oxides on the metal prior toreflow. Formic levels are maintained by a bubbler system and monitored in real time.
