Kester Solder Wire Shelf Life

This document is to be used by our customer to determine if the outdated wire in accordance with kester s shelf life is still a workable product.

Kester solder wire shelf life.

Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. The shelf life for each product is stated on its technical data sheet. The use of 275 no clean flux results in an extremely clear post soldering residue without cleaning. 361 f 183 c lead free.

Kester 44 rosin flux is an activated rosin formula for use in flux cored solder wire. Lead free reflow profile recommended reflow profile for kester solder paste formulations containing the sn96 5ag3 5 and sn96 5ag3 0cu0 5 alloys download article k100ld k100 case studies summary this powerpoint pictorial examines a successful implementation of k100ld and k100 lead free alloys at smt dynamics and ayrshire electronics. Solder flux cored 285 63 37 015. Shipping info shelf life start.

Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70 lead the shelf life is two years from date of manufacture. Other alloys have a shelf life of three years from date of manufacture. 27 awg 28 swg.

031 diameter 66 core. Also the date of manufacture and date of expiration is noted on the product label. It is comprised of 95 percent tin and 5 percent antimony or sn95sb5. Storage must be in a dry non corrosive environment between 10 40 c 50 104 f.

I bought this after reading the following from kester site. Other alloys have a shelf life of three years from date of manufacture. The shelf life of cored solder wire is based on the chemistry of the flux core and the protective alloy covering of the wire. Kester 275 no clean flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry.

It is simply a means to see if the wire still performs to the customer s needs. Bar bar solder has no limited shelf life given the following conditions. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. For alloys containing more than 70 lead the shelf life is two years from date of manufacture.

The shelf life of c hemical products will vary based on the chemistry of the formula. Moisture sensitivity level msl 1 unlimited melting point.
