Alpha to Present Low-Temp Papers at SMTA China South Technical Conference


Reading time ( words)

Alpha Assembly Solutions, the world leader in the production of electronic soldering and bonding materials, will present two of its most popular papers “Low Temperature Soldering Using Sn-Bi Alloys” and “Low-Temperature SMT Process Implementation” at the upcoming SMTA China South Technical Conference on August 28, 2018 in Shenzhen, China.

The first technical paper, titled “Low-Temperature Soldering Using Sn-Bi Alloys“ will be presented by Jackson Chan, Senior Technical Services Manager for Alpha Southern China, and illustrates how low-temperature solder alloys are preferred for the assembly of temperature-sensitive components and substrates. The alloys in this category are required to reflow between 170°C and 200°C soldering temperatures. Lower soldering temperatures result in lower thermal stresses and defects, such as warping during assembly, and permit use of lower cost substrates. Sn-Bi alloys have lower melting temperatures, but some of its performance drawbacks can be seen as deterrent for its use in electronics devices. Therefore, the technical presentation will show that non-eutectic Sn-Bi alloys can be used to improve these properties and further align them with the electronics industry specific needs. The physical properties and drop shock performance of various alloys will be evaluated, and their results will be analysed in terms of the alloy composition, including Bi content and alloying additions.

Another paper, “Low-Temperature SMT Process Implementation,“ will be presented by William Yu, Senior Technical Services Manager for Alpha Northern China. This paper will address how low temperature SMT process to enable tremendous component and laminate cost savings. Replacing the costly wave soldering process by a majority of smart adopters of SMT enabled shorter process flows that saved not only energy, but also largely mitigated the damaging effects of thermal shock that often results from wave soldering.
