Indium Corporation disclosed the global availability of CW-807RS, a new high-reliability, halide- and halogen-free flux-cored wire that improves wetting speeds and cycle times for electronics assembly and robot soldering applications.

CW-807RSis a no-clean formula designed to maximise the solderability of a halogen-free cored wire solder flux. It is an upgraded version of Indium Corporation’s CW-807 formula, which has been popular with electronics assemblers and other customers for many years. This new halogen-freeversion will provide improved wetting speeds and contains the company’s industry-leading spatter control technology.

Halogen-free CW-807RS delivers several benefits to users, including faster wetting speeds, Clear residues for electronics assemblers that use high (>385°C) tip temperatures and tend to experience charring and tip build-up and improve cycle times in robotic soldering applications.

Robert McKerrow, Product Manager for Flux-Cored Wire, Wave Solder Flux, and Bar Solder at Indium Corporation, said, “The improved wetting and spatter performance make CW-807RS an excellent no-clean, high-reliability flux-cored wire option for many of our customers, especially in robotic soldering applications. We’re excited to now offer this solution, combining cutting-edge innovation with proven technology to meet the needs of our customers.”

CW-807RS provides exceptional benefits in manual and robotic soldering applications requiring an “L” IPC classification and halogen-free wire, as well as in manual and robotic soldering applications requiring extra wetting power to achieve higher throughput while remaining halogen-free. Additionally, the spatter control technology within the flux produces an aesthetically pleasing board post-soldering by leaving minimal spattering and a clear to light-coloured residue.
