HNC600-1.2-500G
NC600( No-Clean)
Utilizing synthetically refined resin and a very effective
activator, NC600 wets and spreads like an RA type.
NC600 exhibits virtually no splattering. NC600
conforms to QQ-S-571 and J-STD-004
Alloy Sn60/Pb40
Melting Range 183-190 C
Flux Core
Qualitek has developed a no clean flux system that may be used for both lead-containing alloys and lead-free alloys. It provides the fluxing activity levels that promote fast wetting action and maximum wetting spread. Utilizing synthetically refined resin and very effective activator, NC600 wets and spreads like an RA type flux core. NC600 exhibits virtually no spattering and leaves minimal residue.
Main Features
- Excellent wettability
- Yields clear, non-conductive residues

Wire Diameter
Sn63/Pb37 NC600 Delta Solder Wire is available in a variety of diameters. The chosen diameter is based on application methods, pad size, and desired solder joint volume. Generally, the diameter of the wire should be slightly larger than the width/diameter of the joint or connection to be soldered. Below is a list of standard diameters.

Flux Percentage
Qualitek utilizes a state-of–the-art automatic wire extrusion and wire drawing machines to manufacture consistent solder. The introduction of flux core in the wire extrusion process involves continual monitoring of flux percentage to ensure minimal flux voids and irregular wire. Typical flux percentage for leaded solder is 1.1 – 3.3%.
Physical Properties
Solder Composition
Qualitek has developed a no clean resin based core flux with alloy composition, Sn63/Pb37, which is a eutectic alloy. Qualitek Sn63/Pb37 alloy conforms to and exceeds the impurity requirements of IPC-J-STD-006C.

Flux Residues & Cleaning
NC600 is a no clean formulation; therefore, the residues do not need to be removed for typical applications. If residue removal is desired, the use of Everkleen 1005 Buffered Saponifier with a 5-15% concentration in hot 60 °C (140 °F) de-ionized water will aid in residue removal.
