Indium Corporation will feature its WS-446HF Flux for both flip-chip and ball-attach processes at SEMICON Taiwan 2019, September 18-20, in Taipei, Taiwan.

WS-446HF flux is a robust, NIA (no intentionally added),halogen-free, water-wash flux that is designed to provide one simple solution to complicated applications, especially those with a single cleaning step for both BGA ball-attach and flip-chip processes. It has a powerful activator system to promote good wetting on even the most demanding substrate metalizations, such asCu OSP, ENEPIG, and ENIG. WS-446HF helps to improve production yield by minimizing non-wet open defects, missing balls, and eliminating Electro-Chemical Migration (ECM).

WS-446HF:

  • Promotes excellent solderability and wetting on a wide range of surfaces
  • Cleans well with room temperature DI water              
  • Eliminates ECM or dendrite formation caused by residue
