The Chemical Connection: The Consequences of Additive Metallizing on Etching Steps
MacDermid Alpha Electronics Solutions, a leading supplier of integrated materials and chemistry solutions for the electronics industry, announced the launch of ALPHA® OM-377, a no-clean solder paste engineered for ultra-fine feature printing in advanced electronics assemblies.
The formulation is designed to support long-term electrochemical reliability while helping manufacturers reduce processing and print defects in high-volume production environments.
As electronics continue to miniaturize, component geometries are shrinking while assembly tolerances become increasingly tight across mobile, wearable, and other miniaturized, high-functioning applications. Manufacturers continue to advance yield and process control as ultra-fine geometries scale into high-volume production. These demands require materials capable of delivering reliable defect mitigation at ultra-fine feature sizes.
ALPHA OM-377 is engineered to address these challenges through:
- Ultra-fine feature printing down to 008004 component sizes
- Consistent solder paste transfer efficiency across fine-pitch designs
- Superior electrochemical performance to support long-term operational reliability
- Improved first-pass yield through reduced Head-in-Pillow (HiP) and Non-Wet Open (NWO) defects
- Reliable wetting performance on brass and nickel surfaces
These capabilities enable manufacturers to maintain high throughput, improve process control, and confidently scale high-density, low-standoff assemblies using fine-pitch components.
ALPHA OM-377 delivers stable performance across both printing and reflow, supporting consistent assembly outcomes in demanding production environments. The advanced chemistry supports no-clean processing with low post-reflow residue suited for dense designs, while its halogen-free composition aligns with current environmental and compliance requirements for high-volume manufacturing.
“Ultra-fine feature designs require consistent printing and reflow performance at production scale,” said Sam Foo, Regional Product Manager, Solder Paste. “ALPHA OM-377 is designed to help manufacturers protect yield, maintain process stability, and support reliable assembly performance in high-density applications.”
As consumer electronics continue to miniaturize while integrating greater functionality, materials capable of supporting scalable ultra-fine feature assembly will remain critical to next-generation electronics manufacturing.
