Soldering Process For Kester 44:
Solder iron tip temperatures are most commonly between 315-371°C (600-700°F) for Sn63Pb37 and Sn62Pb36Ag02 alloys.  Heat both the land area and component lead to be soldered with the iron prior to adding Kester 44 cored wire.  Apply the solder wire to the land area or component lead.  Do not apply the wire directly to the soldering iron tip.  If needed, Kester 186 Mildly Activated Rosin Flux may be used as a compatible liquid flux to aid in reworking soldered joints.  Kester 186 Mildly Activated Rosin Flux is also available in Flux-Pens® for optimum board cleanliness.
Storage, Handling, and Shelf Life
:
Storage must be in a dry, non-corrosive environment.  The surface may lose its shine and appear a dull shade of grey.  This is a surface phenomena and is not detrimental to product functionality.  Flux cored solder wire has a limited shelf life determined by the alloy used in the wire.  For alloys containing > 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.
