Indium Corporation will feature its WS-446HF Flux for both flip-chip and ball-attach processes at the China Semiconductor Packaging Test (CSPT) Technology & Marketing Annual Conference, September 8-10, Wuxi, China.
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 metallizations, such as Cu OSP, ENEPIG, and ENIG. WS-446HF helps to improve production yield by minimizing non-wet open defects, missing balls, and eliminating electrochemical 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
From water-soluble and ultra-low/near-zero residue no-clean flip-chip fluxes to system-in-package (SiP) water-soluble and no-clean solder pastes, Indium Corporation has an industry-proven portfolio of products that meet the current and evolving challenges encountered in fine-pitch SiP and Heterogeneous Integration applications.
