Halogen-Free Flux Paste

RM938(HF)

FG003

RM938(HF) is a no-clean, rosin-based flux paste developed for the attachment of lead-free solder balls to BGA and CSP components. It features a halogen-free activation flux system, making it suitable for environmentally friendly manufacturing processes. The paste delivers reliable performance across a wide range of reflow profiles, both in air and nitrogen atmospheres.

FG003 is a no clean, rosin-based flux paste developed for the attachement of lead-free solder spheres to BGA and CSP applications.
The flux formulation employs a halide-activated system with high activity, making it suitable for a wide range of applications.
It provides consistent and reliable performance across a broad range of reflow profiles in both air and nitrogen environments.

  • Shiny and smooth joint after reflow.
  • Good reliability and shelf life.
  • Suitable for stencil transfer application.
  • Good stencil life with small variations for long hours of printing
  • Good tackiness that holds the components in place for 8 hours.
  • Good coalescence under air reflow up to 0.2 mm solder balls.
  • Non corrosive, passes standard IPC SIR test and JIS copper corrosion test.
