Kester Solder NTE Electronics

For anyone that has used fine solder wire, you know that a 1 pound (453 gram) spool

literally lasts forever.

For this reason industrial Electronics is now offering Kester Lead free solder in new smaller quantities of Silver solder in 100 gram and 250 gram per spool on select Kester fine solder wire.

This will help to save considerable waste, reduce inventory costs, and minimize out of

date product.

The following fine silver solder wires are available in .010" (.25mm), .015" (.38mm), & .020" (.50mm) with Alloy of tin 96.5 sliver 3.0 and copper .5 Sn96.5 Ag3.0 oCu0.5

diameters, in either 100 or 250 gram spools.

275 No-Clean Cored Wire for Lead-Free and Leaded Alloys

Product Description

Kester 275 Flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. The use of 275 results in an extremely clear post-soldering residue without cleaning. The unique chemistry in 275 was also designed to reduce spattering common to most core fluxes. 275 can be used for both lead bearing and lead-free soldering.

Performance Characteristics:

Colorless translucent residues
Improves wetting performance
Excellent solderability and fast
wetting to a variety of surface fin- ishes
- Eliminates the need and expense of cleaning
- Low smoke and odor
- Low spattering
- Compatible with leaded and lead- free alloys
- Classified as ROL0 per J-STD-004
- Compliant to Bellcore GR-78

Solder iron tip temperatures are most commonly between 315-343°C (600-650°F) for Sn63Pb37 and Sn62Pb36Ag02 alloys, and between 371-400°C (700-750°F) for lead-free alloys. Heat both the land area and component lead to be soldered with the iron prior to touching the land with the cored wire. Do not apply the wire directly to the soldering iron tip. If needed, Kester 959T or 958M no clean flux may be used as a compatible liquid flux to aid in reworking soldered joints. Kester 959T is available in Flux-Pen® for optimum board cleanliness.
