Value Collection 1429463NCP10311 63/37 Solder Wire 1 Lb

Product Description

The VALUE COLLECTION 1429463NCP10311 is a 63/37 tin-lead solder wire designed for precision electrical and electronic soldering work. The 63/37 alloy ratio — 63% tin, 37% lead — is a eutectic formulation that transitions directly from solid to liquid without a plastic phase, producing clean, reliable joints with minimal bridging. At 0.031 inches in diameter (21 gauge), this wire feeds smoothly through solder stations and hand irons. It uses a no-clean flux core, meaning residue left after soldering does not require post-process cleaning under most conditions. This spool ships at 1.125 pounds and is used by electronics technicians, HVAC control board repair technicians, and electricians performing low-voltage circuit work.

This solder wire is suited for through-hole and surface-mount rework, control board repair, and general electrical joint work in residential and light commercial applications. The 0.031-inch gauge is particularly well matched to fine-pitch component work and delicate circuit board soldering where larger-diameter solder wire would deposit excess material. The no-clean flux designation makes it practical for field repair situations where thorough board cleaning is not feasible.

Key Features

• 63/37 eutectic alloy for fast, clean solidification with no plastic-phase transition
• No-clean flux core eliminates mandatory post-solder cleaning in most applications
• 0.031 inch (21 gauge) diameter suits fine-pitch and delicate circuit board work
• 50-core flux distribution promotes consistent flux delivery across the joint
• Tin-lead formulation compatible with standard soldering irons and solder stations

Compatibility

Designed as a general-purpose 63/37 tin-lead solder wire compatible with standard electric soldering irons, solder stations, and rework equipment used in electrical, electronic, and HVAC control board service applications.

Installation Notes

This product is handled by electronics technicians and electricians performing circuit board repair or low-voltage wiring connections. Ensure the soldering iron tip is properly tinned and set to a temperature appropriate for 63/37 alloy before use. Work in a ventilated area, as flux fumes are released during soldering. Follow applicable workplace safety guidelines for lead-containing materials, including hand washing after handling.
