Lead Free, Zero Halogen, No Clean Solder Paste for Jet Printing with SAC305 alloy

ALPHA® LUMET® JP510 is a lead-free, Zero-halogen no-clean solder paste designed for use in Jet Printers. The paste has clear, colorless flux residue, which is ideal for LED package-on-board assembly with small dot sizes by jet printing.

Additionally, ALPHA® LUMET® JP510 is highly pin testable and achieves IPC7095 Class III voiding performance.


  • Long, High Tack Force Life: ensures high pick-and-place yields, good self-alignment
  • Wide Reflow Profile Window: allows best quality solderability of complicated, high density PWB assemblies in both air and nitrogen reflow, using ramp and soak profiles, as high as 175 to 185°C
  • Reduced Random Solder Ball Levels: minimizes rework and increases first time yield
  • Excellent Coalescence and Wetting Performance: coalesced 180µm circle deposit, even at high soak profile environment
  • Excellent Solder Joint and Flux Residue Cosmetics: after reflow soldering, even using long/high thermal soaking, without charring or burning
  • Excellent Voiding Performance: Meets IPC7095 Class III Requirement
  • Halogen Content: Zero Halogen, no halogen intentionally added
  • Residue: Excellent Pin Testing property and Pass JIS Copper Corrosion Test
  • Safe and Environmentally Friendly: Materials comply with RoHS and Halogen-free requirement (see table below), as well as TOSCA & EINECS
