Formic Acid and Hydrogen Reduction Compatible Tabletop Vacuum Solder Reflow Device VSS-300

300mm square compatible model. Can be linked with loaders and unloaders for mass production. Made by Unitec Japan.

This product is a tabletop vacuum solder reflow device that enables a maximum of 0.01% void-free soldering, making it suitable for addressing challenges related to fluxless and lead-free applications. It supports the removal of oxide films on the metal surfaces to be joined through "hydrogen reduction" and "formic acid reduction." The powerful reducing effect of formic acid enhances wettability even without flux. Additionally, despite its compact design, which is among the smallest in the industry, it consolidates the functions and performance needed for everything from prototype development to mass production into a single unit. With a wide variety of reflow profile settings and excellent temperature control, it achieves high-reliability mounting standards required for power devices and aerospace development. **Features** - Rapid heating at a speed of 2.5°C per second, significantly reducing takt time with water cooling - Maximum reachable temperature of 450°C (optional up to 650°C) - Compatible with various atmospheric environments such as formic acid, hydrogen, and nitrogen - Almost perfectly realizes the set temperature profile, with high repeatability and nearly zero overshoot - The in-plane temperature difference on the heating plate is nearly zero, allowing for uniform heating of large workpieces *Free demo requests are also accepted.
