ProsKit Solder 63% 100G Dia 0.8mm

The Proskit 63/37 solder wire is a highly reliable eutectic alloy for drone electronics, producing clean, shiny joints that withstand high-vibration FPV flights. Because it transitions directly from a liquid to a solid state with no semi-solid plastic phase, it drastically reduces the risk of cold solder joints. At 0.8mm in diameter, it provides precise flow control—thin enough for delicate receiver pads on flight controllers, yet substantial enough to tin ESCs and XT60 pigtails when fed steadily.

Key features

• Sn63/Pb37 eutectic blend: Melts and solidifies instantly, ensuring secure electrical connections even if the wire shifts slightly during cooling.
• Integrated rosin flux core: Promotes rapid wetting and removes oxidation from copper pads without requiring external flux paste for standard joints.
• 0.8mm diameter: The ideal middle-ground thickness for versatile quadcopter wiring, from microscopic UARTs to heavy-gauge motor wires.
• 100g spool: Provides ample solder for multiple full builds, motor swaps, and ongoing field maintenance.

Specifications

• Alloy composition: Sn63 / Pb37 (63% Tin, 37% Lead)
• Wire diameter: 0.8 mm
• Spool weight: 100 g
• Melting point: 183°C

For optimal results on heavy-mass joints like XT60 battery leads or large ESC power pads, pair this solder with an iron capable of at least 65W and a broad chisel tip to ensure rapid heat transfer.
