Solder Wire

"245" No-Clean

"245" is a halide-free; rosin based no-clean core flux that
provides excellent wetting combined with optimal reliability
and cosmetics. "245" is compliant to Bellcore GR-78-CORE
and is classified as ROL0 per J-STD-004.

"331" Water Soluble

"331" is a high-activity water-soluble core flux for soldering
difficult metals. "331" is designed for optimal cleanability,
along with minimal smoke and odor. The residues from
"331" must be removed. "331" is classified as ORH1
per J-STD-004.

"285" RMA

"285" is an RMA based core flux that provides wetting
action comparable to that of typical RA fluxes. Although
"285" is an RMA-based material, the residues are non­corrosive if not cleaned. "285" is categorized as ROL0
per J-STD-004.

Kester “44”

®

Rosin “44”®is a high activity RA core flux designed for
excellent instant wetting action, even on Nickel surfaces.
Although “44”

®

is a RA-based material, the residues are

non-corrosive if not cleaned. Per J-STD-004, “44”

®

is

classified as ROM1 flux.

Kester Solid Wire

Kester's solid wire solder, without flux core, is manufac­tured using virgin metals and strict quality control stan­dards. Conforming to IPC/J-STD-006A and ASTM B32.
