Alpha, the world leader in the production of electronic soldering and bonding materials, will present a technical paper at CISTF 2015 which is hosted by ITRI-IPC from September 17-18, 2015 at Suzhou Grand Metropark Hotel in Suzhou, China.
The technical paper, titled “Thermal and Mechanical Reliability of Low-Temperature Solder Alloys for Handheld Devices” will be presented by Andy Yuen, Technical Services Director of Alpha Southern China. Andy will discuss the use of micro-additives in eutectic Sn-Bi alloys to improve thermal fatigue and mechanical shock properties for handheld devices.
“We developed a new low temp, Pb-free, no-silver alloy with enhanced mechanical properties, particularly higher tensile strength and impact energy, which resulted in improved drop shock performance over standard SnBi alloy systems” said Andy. “The alloy is capable of delivering high reliability performance at lower soldering temperatures, leading to increased throughput and production value in your assembly process.”
The presentation also concluded that the new low temp alloy has superior creep strength thus enhancing thermal cycling performance. This low temp alloy, known as ALPHA® SBX02, is commercially available. Low temperature solder pastes containing this alloy are being used in applications such as portable devices, flexible circuits and in assemblies of high efficiency LEDs.
