High-Performance Soldering Flux Paste

Soldering Flux Paste – RMA-223 / NC-559-ASM (Tube) & ZJ-18 (10g Cup) – No-Clean SMD Rework Flux

This professional-grade soldering flux collection is designed for BGA reballing, SMD soldering, PCB repair, and precision electronic rework applications.

Now available in four carefully selected variants to meet different soldering requirements — from general PCB repair to high-precision BGA chip rework.

Each variant provides excellent wetting performance, strong solder joint formation, and reliable insulation while maintaining minimal residue and high SIR value.

 

Variants

RMA-223 – 10ml Syringe Tube	A moderately active rosin-based flux widely used in SMD and mobile repair work. It provides smooth soldering results, good insulation, and high SIR value.
NC-559-ASM – 10ml Syringe Tube	A high-viscosity, no-clean professional flux designed for precision BGA reballing and advanced chip-level repair.
NC-559-ASM – 30ml Syringe Tube	Professional bulk-use version of NC-559-ASM, ideal for high-volume repair workshops and industrial environments.
ZJ-18 – 10g Cup (Jar Type)	ZJ-18 is a moderately active rosin-type soldering paste supplied in a convenient 10g jar format, suitable for general PCB soldering and repair applications.
