RX18 Cored Solder Wire

RX18 No Clean Cored Solder Wire was formulated for use in automated and robotic soldering processes. Winner of Circuit Assembly’s 2019 NPI (New Product Introduction) Award, RX18 is compatible with all alloys and promotes fast wetting on all surface finishes.

RX18 flux cored wire is developed to provide improved thermal transfer and rapid solder penetration into plated through hole or surface mount interconnections while reducing voiding. It is designed with specialized packaging which ensures consistent, accurate, jam-free automatic feeding for robotic soldering.

RX18 cored solder wire’s post soldering residues are minimal, clear and pass IPC-004 current revision SIR and corrosion requirements, enabling its reliability in any application ranging from military and automotive to consumer electronic assemblies.

RX18 is available in multiple lead-free alloy options which are REACH compliant and make it the ideal RoHS solder wire for electronics assembly. It is also available in leaded alloys such as Sn63/Pb37.
