Solder Bar, Leaded, Sn5Pb95, Zero-Halogen, High Reliability, 1 2/3lbs
Recently, manufacturers in the Electronic Assembly industry have expressed concern over no-clean flux residue and its influence on reliability. This concern has been heightened by miniaturization and high-density board design trends.
To ensure high reliability, Kester has followed specific experimental procedures based on simple chemical fundamentals. These protocols discriminate against two primary chemical mechanisms causing reliability failures: corrosion and electrochemical migration. Including industry standards and customer-specific testing, Kester is proud to present their series of chemically reliable products.
Storage, Handling and Shelf Life
Storage must be in a dry, non-corrosive environment between 10 to 40°C (50 to 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.
