MacDermid Alpha Introduces Ultra-Fine Feature Solder Paste at Productronica China in Shanghai The Assembly Solutions division of MacDermid Alpha Electronics Solutions, a world leader in the production of electronics soldering and bonding materials, will introduce ALPHA® OM-372 its latest ultra-fine feature solder paste innovation at Productronica China at the Shanghai New International Expo Centre in Shanghai, China from March 17-19. ALPHA OM-372 is designed to provide ultra-high electrochemical reliability on fine pitched, low standoff components. ALPHA OM-372 is formulated to deliver low post reflow residue and superior transfer efficiency on fine feature pads as low as 80x130µm (008004). A combination of these best-in-class features as well as excellent HIP and NWO performance makes it ideal for a broad range of high board density applications requiring smaller, thinner, and lighter form factor components.
