Indium Corporation Announces Spanish-Language Voiding Workshop Webinar

Indium Corporation’s Iván Castellanos, Technical Services Manager for Latin America, will host an Avoid the Void®InSIDER Series workshop on how to avoid voiding in bottom termination components (BTCs) on Tuesday, September 22 at 12 p.m. Central Time (Mexico)/7 p.m. Central European Summer Time (Madrid, Spain).

BTCs are one of the most common packages in electronics today with the highest growth rate due to their small size, excellent electrical performance, and ability to transfer heat away from the integrated circuit (IC). In this workshop, Understand and Troubleshoot Voiding in Bottom Terminated Components, Castellanos will discuss how voids form in QFNs and how to minimize them. He’ll also cover factors that affect voiding, such as stencil design, stencil thickness, reflow profile, solder paste particle size, and solder pastes. The use of solder preforms to minimize voiding will also be presented.

Indium Corporation’s InSIDER Series is a free program designed to deliver expert technical content, share industry knowledge, and promote professional growth using a virtual platform. Current and future webinars can be found at
