Pb-Free Solder Paste delivers high first pass yields.

Press Release Summary:

Indium8.9HF1-P combines max stencil printing performance with optimized no-clean residues to enhance probe testing. Able to print on apertures with area ratios <0.5 using minimal print pressures, product conserves testing time by eliminating false failures. Halogen-free oxidation barrier technology eliminates defects such as head-in-pillow and graping, while soft residue after reflow is penetrable by test probes and remains probe-testable after multiple reflows.

Indium8.9HF1-P Delivers High First Pass Yields for In-Circuit Testing

Indium Corporation introduces a new Pb-free solder paste designed to combine best-in-class stencil printing performance, using Indium’s unique halogen-free oxidation barrier technology with optimized no-clean residues for enhanced probe testing. Indium8.9HF1-P saves time and money on testing by eliminating false failures and giving the highest first pass yields.

“Indium8.9HF1-P has proven low cost-of-ownership for PCB assemblies,” said Tim Jensen, Global Product Manager for Indium Corporation’s PCB assembly products. “Our customers have been asking for a high-performance solder paste that combines excellent printability with probe-testability. This solder paste delivers on all counts. What this means is that Indium8.9HF1-P will deliver long-term reliability for our customers’ end products.”

Indium8.9HF1-P provides high transfer efficiency, and consistent print performance, even at high speeds. Additionally this paste has a robust response-to-pause, lessening the need for frequent under-stencil wiping. Indium8.9HF1-P prints well on apertures with area ratios <0.5, using low print pressures. Indium Corporation’s unique oxidation barrier technology enhances reflow performance, eliminating defects such as head-in-pillow and graping.

Indium8.9HF1-P is optimized for probe-testability in two ways: it has a soft residue after reflow, which is easily penetrable by test probes, and this residue remains probe-testable after multiple reflows, time between reflow and test, and baking.
