Product Description
Kester 268 Flux-Cored Wire is a zero-halogen wire optimized for robotic soldering applications. With its unique chemistry
system, 268 provides consistent workability performance for both robotic and manual soldering in the electronics industry,
with performance equivalent to conventional halogen/ halide-based systems. 268 provides a clean release which
prevents occurrences of bridges and protrusions, even in narrow-pitch automated drag soldering. The use of 268 results
in a clear post-soldering residue without the need for cleaning. 268 is classied as Type ROL0 ux under J-STD-004B
specications. 268 is zero-halogen and halide-free with no intentional addition of bromine and chlorine, conforming to the
strictest requirements of IEC 61249-2-21, JPCA-ES-01 and IPC-410B specications.
