PRODUCT DESCRIPTION
CircuitWorks Lead-Free Flux is designed
specifically for all lead-free soldering. The
convenient quart size containers offers a more
convenient package small OEM’s and board
shops. The Lead-Free Flux 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 leadfree soldering.
Flux is noncorrosive and halide-free
Can be used for soldering with lead-free or
Tin/Lead solders
Excellent mate rial compatibility
Fast drying
RoHS compliant
High thermal stability

Lead-Free Flux is
generally compatible with most materials
used in the electronics industry. As with
any fluxing agent, material compatibility
should be determined on a non-critical
area prior to use.
