Indium TACFlux 020B Solder Flux FLUXOT-84237-10CC | 10cc Syringe
Indium TACFlux 020B — No-Clean Solder Flux, 10cc Syringe (FLUXOT-84237-10CC)
Indium TACFlux® 020B (part number FLUXOT-84237-10CC) is a no-clean, halogen-free solder flux formulated for both SnPb and Pb-free soldering processes. TACFlux 020B passes SIR (Surface Insulation Resistance) testing in the unreflowed state, making it suitable for applications where flux residue may remain on the board after soldering. Supplied in a 10cc syringe for precision dispensing in hand soldering, selective soldering, and rework applications.

Frequently Asked Questions
What does "no-clean" mean for TACFlux 020B?
No-clean means the flux residue left after soldering does not require removal under normal conditions. TACFlux 020B residues are formulated to be electrically safe and non-corrosive when properly reflowed. However, if the flux is not fully activated during soldering (unreflowed residue), it still passes SIR testing, providing an additional margin of safety.
Is TACFlux 020B compatible with lead-free soldering?
Yes — TACFlux 020B is formulated for both SnPb (tin-lead) and Pb-free (SAC305, SAC405, and similar) alloys. It provides reliable wetting and activation across the temperature ranges used for both alloy systems.
Is TACFlux 020B halogen-free?
Yes — TACFlux 020B is halogen-free, meeting the requirements of IPC J-STD-004 for halogen-free flux classification. This makes it suitable for applications where halogen content must be minimized for environmental or reliability reasons.
What is the 10cc syringe format used for?
The 10cc syringe format (FLUXOT-84237-10CC) is designed for precision manual dispensing in hand soldering, rework, and selective soldering applications. The syringe allows operators to apply a controlled amount of flux directly to the joint or pad without contaminating surrounding areas.
Where can I find the TACFlux 020B Technical Data Sheet?
The official Indium Corporation TDS for TACFlux 020B is available directly from Indium's document library. Contact MTE Solutions for assistance locating the current revision of the TDS or SDS for this product.
