Solder Paste

ALPHA® OM-350 is a lead-free, no-clean solder paste suitable for fine feature printing and reflow using most demanding soak reflow profiles in air and nitrogen atmospheres. The outstanding reflow process window of ALPHA OM-350 delivers good soldering on OSP-Cu, Immersion Ag, Immersion Sn, ENIG and Lead-Free HASL surface finishes.  ALPHA OM-350’s compliance with ROL0 IPC and IPC Class III voiding classifications ensures maximum long-term product reliability. Compliance to environmental standards, including RoHS allows global application of ALPHA OM-350.

Features & Benefits

  • Excellent Pin-in-Paste (Paste-in-Hole) Performance: demonstrated both for printing, dispensing (or pin transfer) SMT applications.
  • Long Stencil Life: consistent performance for at least 6 hours of continuous printing without addition of new paste. 24 hour SMT production ability achieved from 20oC up to 32oC (68oF - 90oF) harsh environments.
  • Stable Paste Viscosity: allows wide storage and handling window at temperatures up to 30oC for 21days,and up to 25°C for one month.
  • High Tack Force: ensures high pick-and-place yields, good self-alignment and a low tomb-stoning defect rate.
  • Wide Reflow Profile Window: allows best quality solderability of complicated, high-density PWB assemblies in both air and nitrogen reflow, using straight ramp or soak profiles up to 200°C.
  • Robust Solderability: proven to handle difficult wetting requirements of critical lead-free components, such as CSP and QFN…etc. on a variety of lead-free board finishes, OSP-Cu, Immersion Ag, Immersion Sn, ENIG & LF HASL.
  • Reduced Random Solder Ball Levels: minimizes rework and increases first time yield.
  • Voiding Performance: meets highest IPC classification of Class III for important ball grid array components.
  • Excellent Solder Joint and Flux Residue Cosmetics: after reflow soldering even using long/high thermal soaking without charring or burning.
  • First-rate Reliability Properties: excess variety of industry and customer standards, halide free material graded ROL0 according to IPC classification.
  • Safe and Environmentally Friendly: materials comply with RoHS requirement, as well as TSCA & EINECS.
