HELLER Industries has developed a vacuum module that inserts directly in its reflow oven line to meet new rising demand of high volume, void-free, automated inline soldering. Vacuum module can be inserted in zone directly after reflow peak (liquidus) has occurred or an IR Panel can be added to the chamber to reach reflow peak under vacuum. Convection reflow with vacuum module is continuous and allows thermal profiles to be directly ported from non-vacuum reflow applications to achieve low COO and high UPH.
