Solder Bar, Leaded, Sn63Pb37, Zero-Halogen, 1 2/3lbs, Ultra-Low Dross
Tin-Lead (SnPb) Solder Bar
Manufactured by a special process that controls the inclusions of oxides and metallic and non-metallic impurities, Kester Ultrapure is the industry standard Solder Bar for use in high-tech electronic applications where lower surface tension and hole filling ability are essential. The purity of Ultrapure meets the requirements of IPC/J-STD-006C and will conform to these requirements when purchased directly or through stocking distributors.
Ultra-Low Dross
Kester Ultra-Low Dross Solder Bar was developed to provide lower dross in wave solder, selective solder, and dip solder processes. This product is a step above the Ultrapure line of Solder Bar.
Many solder impurities have been known to contribute to dross formation. Kester Ultra Low Dross integrates low dross technology with Kester's extruded bar manufacturing process. To minimize oxidation and alloy segregation, Kester pours and quickly chills ingots of solder alloy. The ingot is inserted into an airtight hydraulic press, which then extrudes bars in a highly efficient and automated manner.
Storage, Handling and Shelf Life
Storage must be in a dry, non-corrosive environment between 10 and 40°C (50 and 104°F). The surface may lose its shine and appear a dull shade of grey. This is a surface phenomenon and is not detrimental to product functionality. A solder bar has a shelf life determined by the alloy used in the bar. For alloys containing more than 70% lead, the shelf life is 2 years from the date of manufacture. Other alloys have a shelf life of 3 years from the date of manufacture.
