Gold-Alloy Solder Paste
AuLTRA® 5.1
AuLTRA® 5.1 is a no-clean solder paste, formulated with AuSn, that can be used with air or nitrogen reflow processes. It is specifically designed to handle the higher processing temperatures required for Au-based alloys. Ideal for high-power LED module array assembly applications, this product offers a wide processing window and consistent print definition, even those with ultra-fine pitches. In addition to consistent printing and reflow requirements, AuLTRA® 5.1 features superb wetting and low-voiding.
