D1: Choosing Solders for the New Era: Low Cost High Reliability Solder Alloys
Instructor: Ning-Cheng Lee, Indium Corporation
While the electronic industry is advancing rapidly toward miniaturization, two more important drivers actually dictate whether the manufacturers could stay in the game or not - Low Cost, and High Reliability. The former is the ticket to get into the game, while the latter is the ticket to stay in the game. These two drivers exemplified their vital role most astonishingly in solder materials. This course covers the roles of solder composition on cost, and on reliability. After reviewing the role of Ag in both cost and reliability, the solder materials are reviewed from the lowest cost, zero-Ag solders to composition with higher and higher Ag content. Among all of the alloy options present on the market, including the most recent development, the representative alloys are introduced with more details, including materials properties, soldering performance, some of the known failure modes, and the primary merit of these alloys.
Who Should Attend?
Technology directors, technology managers, product managers, design engineers, process engineers, reliability engineers, material scientists, process technicians, anyone who wants to know what are the solder alloys available, and what are the pros and cons about all of the options on solder alloys should take this course.
