90In / 7Sn / 3Ag Lead-Free Indium Solder Wire
90In / 7Sn / 3Ag
Lead-Free Indium Solder Wire
90In / 7Sn / 3Ag lead-free indium solder wire is a flux-coated indium-rich solder wire for convenient low-temperature soldering. It is suitable for electronics assembly, low-temperature soldering, rework, bonding, and customized soldering processes where alloy composition, wire diameter, and flux form need to be matched carefully.
A specialized indium-based lead-free solder wire.
90In / 7Sn / 3Ag is supplied for low-temperature and specialty soldering applications. Compared with standard Sn-based solder wire, indium-containing alloys are often selected when lower process temperature, softer joint behavior, or special bonding requirements are needed. Final suitability should be verified according to substrate, flux system, heating profile, and reliability requirements.
Lead-Free Alloy
Designed for RoHS-oriented electronics soldering and specialty joining needs.
Custom Diameter
Wire diameter can be selected according to process and order requirements.
Flux Options
Solid wire, flux-cored, or flux-coated forms are available for selected alloys.
Stable Handling
Supplied for controlled soldering, rework, bonding, and engineering evaluation.
90In / 7Sn / 3Ag solder wire specifications.
Basic parameters for quick RFQ communication. Because humans apparently enjoy hiding critical purchasing details in screenshots, confirm final diameter, flux type, and packaging before quotation.
