Kester part number 24-6337-8808 delivers a classic Sn63Pb37 eutectic solder wire in a thin .020" diameter format, ideal for precision PCB assembly, electronics rework, and through hole soldering where control and fine detail matter. The 245 Rosin Activated flux core provides reliable wetting and joint quality while minimizing residue, making it a no clean option suitable for both production and repair environments. This 1 lb spool is engineered for consistent melting behavior at 183°C, a characteristic that makes eutectic alloys the professional standard across electronics manufacturing and field service. Kester's US made quality and proven flux chemistry make this a trusted choice for technicians and shops that demand repeatability and clean results without extensive post-solder cleaning.
Key Features:
Alloy Composition: Sn63Pb37 (63% Tin, 37% Lead)
Diameter: .020" (0.5 mm)
Weight: 1 lb (approximately 454 grams)
Package Type: Spool (SPL)
Flux Core: 3.3% No Clean flux core.

Eutectic solder melts and solidifies at the same temperature.
.020" Diameter suitable for smaller to medium sized soldering jobs. No Clean flux designed to be left on the board with minimal cleaning.
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.
