Bismuth (Bi), which is introduced either through the supply chain or by design, is becoming an inevitable element in lead-free electronic products. With the deliberation of all relevant parameters, theoretical and practical, Bi plays a “potent” role in electronic solder systems, which impact the performance and reliability of electronic package and assembly including solder joint performance, tin whisker mitigation, among others. The proper use of Bi can profoundly benefit the performance and reliability, and the improper use could degrade the performance and reliability. An adequate understanding of the property parameters of Bi is critical to product reliability. This webtorial will discuss the relevant aspects of Bi to help dispel misconceptions and to demonstrate performance criteria related to Bi. The webtorial will also highlight the distinction between Sn-based-Bi-containing alloys and Bi-based alloys. The goal is to help achieve the desired level of performance and product reliability. Your questions and issues for solutions and discussions are welcome.
