Cookson Electronics has announced the launch of Alpha Vaculoy SACX-0307 Plus low-Ag Pb-free wave solder and rework alloy for use as a high-performance replacement for SnPb and SAC305.

It is Cookson’s next generation low-Ag alloy in the Alpha SACX alloy range.

SACX-0307 Plus performs at the same level of standard Alpha SACX-0307 with the added benefit of lower copper dissolution.

‘Alpha SACX-0307 Plus offers a lower alloy cost versus higher silver alternatives such as SAC305/387/405, and can be run at lower operating temperatures than most Ag-free, Pb-free alternatives,’ said Mike Murphy, Cookson’s global product manager, wave soldering materials.

‘It also offers excellent wetting on low- to medium-complexity assemblies in either wave rework or selective soldering applications.

‘As with all of our SACX alloys, 0307 Plus has a lower drossing rate compared to most other Pb-free alloys,’ he added.

Alpha SACX 0307 offers excellent hole fill and drainage due to the lower surface tension attributed to the presence of Ag, and it delivers good performance across a range of wave solder flux technologies, said Cookson.
