Spool of 2.0mm 63/37 tin rosin core solder wire 100g

63/37 Tin Rosin Core Solder Wire 100g 2.0mm

SKU CH-HSCS-5PY41

63/37 tin rosin-core solder wire, 100 g, 2.0 mm diameter, melts at 183 °C with 2.0 % flux for electronics repair and DIY work

  • Compatibility/Fitment2MM, 2MM100g
  • 63/37 alloy with 2.0% flux melts at 183°C for fast joints
  • 0 mm diameter feeds smoothly through fine-pitch IC and PCB work
  • 100 g (3.53 oz) spool supplies enough length for extended repair sessions
  • Low melting point reduces thermal shock to sensitive components during soldering
  • Bright wire colour gives clear visual contrast against grey joints for easy inspection

Solder Wire for Electronics Repair

This 100g spool of 63/37 tin rosin core solder wire suits technicians and hobbyists who repair PCBs, ICs or small hardware. The 2.0mm diameter feeds easily through a hand-held iron for fine soldering work and DIY projects.

Rosin Core Flux Included

Flux content of 2.0% removes oxidation during heating so a separate flux pen or paste is not required for most joints. The rosin core activates at the alloy melting point of 183°C, reducing the time the iron dwells on sensitive components.

Low Thermal Shock Alloy

Tin-lead ratio 63/37 melts sharply at 183°C, limiting heat spread into adjacent parts. Bright wire colour lets the user confirm flow visually, while the 2.0mm (0.08 in) thickness balances control with enough volume for typical through-hole and surface-mount joints.

Questions about this item

When will the 100g spool of 2.0mm 63/37 solder wire need replacing?

The spool contains 100g of wire; replacement depends on how much you use for each joint, so a heavy user will need a new spool sooner than an occasional hobbyist.

What limits continuous soldering with this 183°C melting-point wire?

The 2.0mm diameter feeds more solder per second than thinner wire, so the iron tip temperature and your hand speed become the practical limit during long sessions.

Does the 2.0% flux core produce noticeable fumes or heat during all-day use?

The rosin core generates typical soldering fumes when heated to 183°C; good ventilation is recommended for extended work, but the wire itself adds no extra heat beyond the iron.
