Looking for a reliable eutectic solder wire for precision PCB assembly, electronics rework, and through hole soldering? The Kester 24-6337-8814 delivers professional grade performance with its Sn63Pb37 alloy composition and 245 rosin activated flux core at 1.1% concentration. The 0.050 inch diameter makes it ideal for general component soldering on mid sized joints, while the no clean flux formulation means you can leave residue on the board without additional cleaning steps. This made in USA solder melts at 183°C (eutectic), providing fast, reliable joints for technicians and repair professionals who demand consistent results without compromise.
Key Features:
Alloy Composition: Sn63Pb37 (63% Tin, 37% Lead)
Diameter: .050" (1.27 mm)
Weight: 1 lb (approximately 454 grams)
Package Type: Spool (SPL)
Flux Core: 1.1%245 No Clean
Melting Point: 183° C 361° F
Eutectic solder melts and solidifies at the same temperature.
.050" Diameter slightly thicker suitable for larger components. No Clean flux can be left on board after use.
Ultra fine sized diameter useful for precision soldering and micro electronics.
.015" (0.4 mm)
Very fine sized diameter useful for precision soldering and jobs requiring small amounts of solder.
.020" (0.5 mm)
Fine sized diameter used for through hole and and surface mount work. Delivers a Controlled amount of solder.
.025" (0.6 mm)
Ideal for standard circuit board components where precision is needed but not ultra-fine work.
.031" (0.8 mm)
Ideal for fixing circuit boards, replacing components, and general rework. Popular for Arduino, Raspberry Pi, and DIY projects. It's a versatile diameter, often called the "sweet spot" for electronics.
.040" (1.0 mm)
Perfect for surface-mount devices (SMDs) and medium components where precision is key but more solder is needed.
.050" (1.27 mm)
Used for various tasks where a balance of flow and control is required, like general electrical repairs.
.062" (1.5 mm)
medium-thickness wire ideal for general electronics, larger through-hole components, appliance repair, automotive work, and crafts like stained glass
.093" (2.36 mm)
versatile, medium-to-thick wire used for general and heavier-duty electrical, electronics, automotive, and HVAC repairs/manufacturing.
