Abstract
WC-Co cemented carbide has excellent mechanical properties and is widely used in many industrial applications including cold forging dies and cutting tools. The tensile and fatigue properties of WC-20wt%Co cemented carbides with microstructural variations were investigated. Microstructure parameters such as Co binder content, WC particle size, binder mean free path,..... More

Abstract
To improve the sensitivity of impact sensor modules for automotive air bag systems, we developed a flexible module. The impact sensor was soldered with Sn-3.0Ag-0.5Cu (SAC305) solder on a flexible printed circuit board (FPCB) with an organic solderability preservative (OSP) surface finish. Thermal shock (TS) is one of the test..... More
