PRODUCT DESCRIPTION
CircuitWorks Lead-Free Flux Dispensing
Pen is designed specifically for lead-free
soldering. The convenient pen applies flux
where it’s needed with precision control. The
Lead-Free Flux Dispensing Pen quickly
applies a noncorrosive, halide-free, No Clean
flux which meets Bellcore TR-NWT-000078
and passes IPC SF-818 for surface insulation
resistance. Instant wetting action provides
thorough deoxidation of metallic surfaces
providing the best possible surfaces for lead-
free soldering.
Pen dispenser provides controlled and
exact application
Minimizes excess flux on the board
Completely portable packa ge
Flux is noncorrosive and halide-free
Can be used for soldering with lead-free or
Tin/Lead solders
