MacDermid Alpha Electronics Solutions, a leading supplier of integrated materials and chemistries to the electronics industry, will present this week at the SMTA New Delhi Technical Event, Bangalore Chapter. Dr Ansuman Das, Senior R&D Manager at MacDermid Alpha will deliver a technical session titled “Flux–OSP Interaction and Its Effect on Solder Wetting”.
This presentation will explore the critical interaction of flux chemistries with thermally treated OSP layers, examining their ability to remove copper oxides and improve solder wetting. Das will share demonstrated findings that show how carefully selected flux ingredients enhance dissolution and optimize hole-fill performance on pre-reflowed OSP coupons.
