Gold-Alloy Solder Paste

^AuLTRA®3.2

AuLTRA® 3.2 is our gold-tin solder paste designed for higher processing temperatures, making it ideal for assembling high-power LED modules. It works in both air and nitrogen reflow processes and is water-soluble for easy cleaning after soldering. The formulation delivers consistent printing performance, with long stencil life, reliable tack, excellent wetting, and low voiding for strong, high-quality solder joints.
