Uyemura's '22,000-Hour Solution'

摘要

To be marketed under its beta test name, GHS-51, Uyemura International Corp.'s new technology prevents whisker formation in electroplated tin for 22,000 hours - and longer. Whisker crystals of tin and tin-based alloys are the most common culprits in the short circuiting of electronic components. Most often, the cause of tin whisker formation is compressive stress. The proprietary technology developed by Uyemura dissipates compressive stress, preventing whisker formation.GHS-51 uses a high purity anode, and is ideally suited for connectors and semiconductor lead frames. It offers high deposition speeds for rackless and reel-to-reel processing, and high deposition efficiency over a wide current density range. The bath is lead and fluoride free,
