Alpha Introduces New Lead-Free, No-Clean Solder Pastes

Estimated reading time: 2 minutes

Alpha Assembly Solutions is introducing new lead-free, no clean solder paste technologies, the ALPHA OM-353 and the ALPHA OM-535.

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-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.

"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."
