Solder Paste
ICT testable Halogen-Free Solder Paste
- S3X58-HF960
S3X58-HF960 significantly reduces false failures during in-circuit testing (ICT) by preventing flux residue from adhering to test probes, as the newly developed “flux fluidity technology” allows the residue to flow away from the solder surface. In addition, its wetting performance is comparable to that of halogen-containing solder paste and helps minimize void formation regardless of component type.

Unique “Flux Fluidity Technology” to improve ICT performance
Utilizing proprietary flux fluidity technology, the flux system in the S3X58-HF960 improves flux residue flow behavior, ensuring that almost no flux residue remains on the solder fillet surface after reflow.
Ensuring reliable test probe contact!
Improved flux fluidity prevents flux residue from remaining on the solder fillet and ensures reliable pin-to-solder contact performance.
In addition, reduced flux residue on test probes decreases probe maintenance frequency (cleaning/replacement) and associated costs.
Drastically improves in-circuit test consistency
Conventional solder pastes cause flux residue to build up on test probe tips during continuous testing, increasing contact resistance.
The S3X58-HF960 is designed to reduce flux adhesion, ensuring that resistance measurements remain stable throughout testing.
■ICT Characteristics
Low void regardless component design and surface finish
■Voiding results for various components
Ensures up to 1 hour of intermittent printability for enhanced processibility
Eliminates printing issues after extended idle time, allowing stable printing to resume even after 60 minutes of downtime.
■Intermittent printability test results
“Halogen-Free” – Addressing Environmental Requirements
One key aspect of environmental measures is “halogen-free”; today, many companies require final products to be halogen-free.
The halogen-free S3X58-HF960 meets these requirements while providing both reliability and workability.
