Alpha Introduces Revolutionary Low-Temp Solder Paste to Address High-Warpage Assemblies


Reading time ( words)

Alpha Assembly Solutions is introducing ALPHA OM-550, a new low-temperature chemistry paired with Alpha’s HRL1 alloy for assemblies with temperature-sensitive substrates, components and high warpage chips.

"The ALPHA HRL1 alloy was designed to enable near-SAC305 drop shock and improved thermal cycling performance in low temperature assemblies," said Phua Teo Leng, Global Portfolio Manager for SMT Assembly at Alpha Assembly Solutions, a part of the MacDermid Performance Solutions Group of Businesses. "This chemistry and alloy pairing is revolutionary as it reduces the soldering temperature required for SAC alloys by 50°C, while dramatically reducing power consumption and carbon emissions.  Assemblers can now benefit from having a cost-efficient, highly reliable soldering process with up to 99% less warpage and significantly fewer defects, which is truly unique."

ALPHA OM-550 has the characteristics of a modern solder paste designed for motherboards but with the ability to reflow at lower temperatures, therefore minimizing NWO and HIP defects in complex assemblies.

Investigation on the Assembly Process for m03015 and a Brief Look at m0201 Components

11/14/2018 | David Geiger, Robert Pennings, and Jane Feng, Flex
Components continue to shrink in the SMT world, and the next evolution of passive components includes m03015 (009005) and m0201 (008004). The m03015 and the m0201 components will see primary adoption in products that require further miniaturization, which would be SiPs. These modules would then be assembled into products through attachment, another assembly, or via other interconnect methods. This article explores the development of an assembly process (SMT only) for the m03015 component.
