Indium Corporation manufactures a variety of materials for PCB rework, repair, and touch up, including flux-cored wire, liquid rework fluxes, and TACFluxes®.
Flux Cored Wire
Indium Corporation has developed a range of flux-cored wire solutions to meet the needs of virtually every electronic assembly and rework operation from no-clean flux-cored wire for circuit board assembly to activated flux-cored wire for non-sensitive electronics and electrical applications.
No-clean fluxes include:
- CW-807 halogen free for high reliability assemblies
- CW-807M, which has a small addition of halogen activator for more difficult to solder assemblies
- CW-807H for high temperature alloys
- CW-501 is rosin (colophony) free and shows exceptional soldering on a wide range of assemblies
- CW-802 is recommended only when no halogen is a must and the process is well-controlled
Activated fluxes include:
- CW-201, a traditional RA type flux as defined by the legacy Mil-Spec QQ-S-571
- CW-207 formulated using a blend of heat stable clear rosins
- CW-209, which has twice the amount of halogen activator as CW-207
- CW-501, rosin (colophony) free and has exceptionally effective soldering on a wide range of assemblies
Liquid Rework Fluxes
Liquid rework fluxes are packaged in convenient pen dispensers, providing the optimal fluxing with no waste. Flux pens utilize a spring-loaded applicator tip to deliver a controlled amount of flux to the work surface. The user friendly pin-point application is deal for touch-up and light assembly work. Liquid fluxes include:
- FP-500, a halogen-free flux that is compatible with both SnPb and Pb-free assemblies
- NC-771, a halogen-free, low-residue, all-purpose flux that passes the SIR test in the un-reflowed state
- FP-300, a water-soluble flux that is compatible with both SnPb and Pb-free assemblies
TACFluxes®
TACFluxes® have a variety of uses including rework and repair of various electronics assemblies and components, SMT component attach (including BGAs and flip-chips), BGA ball attach, preform soldering, and virtually any application where flux is required. Indium Corporation manufactures a complete line of TACFlux®, which include no-clean, water-wash, and RMA-based fluxes.
Some of the most common TACFluxes® include:
- TacFlux 089: no-clean flux for Pb-free alloys
- TacFlux 089HF: a halogen-free, no-clean flux for Pb-free alloys
- TacFlux 025: a water-soluble flux for Pb-free and SnPb alloys
- TacFlux 020B: a halogen-free, no-clean flux for Pb-free alloy
