Indium Corporation Introduces New Water-Soluble Flux-Cored Wire

Dec 07, 2021

Indium Corporation announces that it is now offering CW-305, a uniquely formulated flux-cored wire that offers superior ease of cleaning in which the post-soldering residue can be removed by using only a warm water-wash.

Indium Corporation’s halogen-free CW-305 cleans so well that residue removal can be delayed for up to 48 hours without affecting ionic cleanliness or visual circuit board appearance. CW-305 is beneficial for electrical hand soldering applications where high flux strength and the ability to clean with water are required, such as touch-up and rework applications for medical, aerospace, and automotive industries. CW-305 is also capable of soldering to heavily tarnished surfaces.

CW-305 is compatible with Indium Corporation’s suite of proven halogen-free, water-wash solder paste and wave fluxes as well as its halogen-containing water-wash fluxes. It is designed for both manual and automated touch-up and component addition.
