Kester 44 Series Solder Wire, Rosin-Core
44 Flux-Cored Wire
Long-time industry-standard activated rosin cored wire for lead free and leaded solder alloys
Kester 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. 44 has virtually dominated the field of activated rosin core solders for well over four decades. An outstanding performance feature of this flux is the “instant-action” wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering. 44 is classified as ROM1 per J-STD-004.
Key Features:
- High-activity RA formulation
- Passes both 85 °C/85% RH and 40°C/90% RH IPC SIR testing
- Excellent solderability to a wide range of metallizations
- Classified as ROM1 per J-STD-004
- Industry-standard RA cored wire
