Formic acid and hydrogen reduction compatible vacuum solder reflow device RSS-160-S

Standard model achieving high-reliability assembly such as fluxless, void-free, and lead-free. Manufactured by Unitec Japan.

The "RSS-160-S" is a desktop vacuum solder reflow device suitable for solving challenges related to no-clean flux, void removal, and lead-free processes. In addition to conventional "flux" and "hydrogen reduction," it also supports reduction using "formic acid." With the powerful reducing action of formic acid, it effectively removes oxide films from metal surfaces such as substrates, achieving improved wettability without flux. Furthermore, by combining vacuum technology, it enables a maximum of 0.01% void-free results. Despite its compact design, which is among the smallest in the industry, it condenses various functions and performance to support a wide range of prototype development. 【Features】 ■ Rapid heating at 100°C per minute, and with water cooling, significantly reduces takt time ■ Maximum reachable temperature of 400°C (optional 500°C) ■ Compatible with various atmospheric environments such as formic acid, hydrogen, and nitrogen ■ Nearly achieves the set temperature profile as is, with high repeatability and almost zero overshoot ■ The in-plane temperature difference on the heating plate is close to zero, allowing for uniform heating of large workpieces *Requests for free demonstrations are also accepted.
