ALPHA® OM-351

Solder Paste

ALPHA® OM-351 is a lead-free, Zero-halogen no-clean solder paste designed for applications where ultra low voiding performance, excellent ICT pin testing first pass yield, and the ability to pass JIS Copper Corrosion test are required.

ALPHA® OM-351 engineered to enable consistent fine pitch printing capability, down to 220μm squares using a 100μm thickness stencil and for 01005 chip components applications. engineered to enable consistent fine pitch printing capability, down to 220μm squares using a 100μm thickness stencil and for 01005 chip components applications.

ALPHA® OM-351 has been shown to yield good coalescence for 170μm circle deposits and excellent IPC Class III ultra low voids performance. This product was engineered for optimum performance under a soak reflow profile in an N2 environment.

Features & Benefits

  • Long Stencil Life: engineered for consistent performance in warm/humid production climates, reducing variations in print performance and paste dry-out
  • High Tack Force Life: ensures high pick-and-place yields, good self-alignment
  • Wide Reflow Profile Window: enables quality soldering of complex, high density PWB assemblies in an N2 environment, using high ramp rates and soak profiles as high as 175°C to 185°C
  • Reduced Mid Chip Solder Balling and Head-in-Pillow Defects: minimizes rework and increases first time yield
  • Excellent Coalescence and Wetting Performance: coalesces well for 170µm small circle deposit at high soak profile nitrogen environment
  • Excellent Solder Joint and Flux Residue Cosmetics: residue does not char or burn after reflow soldering, even when using long/high thermal soaking
  • Excellent Voiding Performance: Exceeds IPC7095 Class III requirement for BGA and best in class for LGA
  • Halogen Content: Zero Halogen, no halogen intentionally added
  • Residue: Excellent ICT Pin Testing property and Pass JIS Copper Corrosion Test
  • Safe and Environmentally Friendly: Materials comply with ROHS, TOSCA, EINECS and Halogen-free requirements (Zero Halogen, see table below)
