Kester 44 Flux-Cored Wire 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 five 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. Under IPC J-STD-004, 44 is classified as ROM1. Despite the increased activity and soldering performance, 44 passes both 85 °C/85% RH and 40 °C/90% RH SIR test methods.

Performance Characteristics:

- High activity RA formulation
- Passes both 85 °C/85% RH and 40°C/90% RH IPC SIR testing
- Excellent solderability for a wide range of metallizations
- Industry standard RA cored wire for decades

- Classified as ROM1 per J-STD-004
