Introducing ALPHA new lead-free, no-clean solder pastes

Alpha Assembly Solutions, the world leader in the production of electronic soldering and bonding materials, is introducing its new lead-free, no clean solder paste technologies.

ALPHA® OM-535 is a low temperature paste with excellent drop shock resistance and electrical reliability for low temperature reflow applications. It produces excellent solder joint and flux residue cosmetics, even when using long/high thermal soaking.
ALPHA® OM-535 key attributes are:

  • Reduces energy consumption in reflow ovens versus standard lead free alloys.  
  • Compatible with all commonly used lead free surface finishes
  • Excellent resistance to random solder balling
  • Delivers very high in-circuit pin test yields
  • Compatible with either nitrogen or air reflow. 
  • Possesses excellent solder drip resistance during reflow. 

ALPHA® OM-353 is an ultra-fine feature print and air reflow-capable solder paste that is ideal for assemblies sensitive to component warpage or processes that require cleaning. It has been tested to give excellent printing performance down to 180µm pad size.

ALPHA® OM-353 key attributes are:

  • Assemblies with ultra-fine features 
  • Assemblies sensitive to component war-page 
  • Processes that currently require cleaning 
  • Components sensitive to flux wicking 

 “These pastes were developed to meet new printing challenges and performance demands”, said Traian Cucu, Global Product Manager for Solder Paste at Alpha Assembly Solutions, a part of the MacDermid Performance Solutions Group of Businesses. “Each has unique assets to quell reliability concerns. OM-353 has excellent transfer efficiency with small area ratios and ensures high pick-and-place yields and good self-alignment. The enhanced properties of low temperature SBX02 alloy combined with the advanced chemistry performance of OM-535 enables the formation of a better solder joint by improving the mechanical performance and cosmetics using low temperature process settings.”
