| Abstract: | Anti-spray-salt corrosion is one of the mostly used approaches to improving reliability of IC packages.Based on mechanism of metal corrosion,novel methods for seam sealing of hermetic packaged ICs using improved welding process,seam sealing of lids with AuSn alloy solder and re-plating after packaging to repair damaged welding lines were proposed to improve anti-spray-salt performance of hermetic packaged IC's by parallel seam sealing. |
