FLUX CORE & WIRE SOLDER

NC601

Wire Solder

NC601 Power Core Wire Solder is a Rosin Activated (RA) activated no clean for repairing through-hole, mixed, and surface mount assemblies. The flux core provides faster melting and higher activity than typical RA flux cores. Its flux is formulated to provide clear, colorless residues. It also allows for maximum activity and high reliability without cleaning, in most situations.

Available Diameters: 0.015, 0.020, 0.032, 0.048, 0.062, 0.098, 0.125

WS101

Wire Solder

WS101 Power Core Wire Solder is a high activity water washable solder for repairing through-hole, mixed, and surface mount assemblies. The flux core provides faster and better flux activity than RA flux cores. WS101 flux is formulated to provide high activity soldering, leaving an easily washable residue without the need for cleaning additives.

About Flux Core Solder

Flux core solder commonly refers to wire solder that has flux in the center of the wire. The concentration of flux inside of wire solder is typically 2% to 3% by weight. Without flux, wire solder would be difficult to use. The metal surfaces being soldered have an oxide layer and heating these surfaces during soldering increases the oxide thickness. 

flux

Flux is required to penetrate the oxides and clean the metal surfaces so the solder can bond properly.  In many cases, flux cored wire solder is used along with a liquid or gel flux.

This additional flux further improves soldering, especially with difficult to solder surfaces.

Flux cored wire solder is available with no clean and water-soluble fluxes, and is made from common solder alloys.  FCT Assembly manufactures and sells a wide variety of soldering products.  These include wire solder, bar solder, liquid flux, gel flux, and solder pastes.  Please contact us for more details.
