Indium Corporation technical support engineer Ryan Mayberry will host a webinar about optimizing reflowed solder thermal interface material (sTIM) processes for emerging heterogeneous integrated assembly (HIA) packages. The webinar, a part of the company’s InSIDER Series, will be held live at 2:00 p.m. (EST), March 30, and made available for on-demand viewing afterward.

Reflowed indium metal has for decades been the standard for sTIMs in most high-performance computing (HPC) TIM1 applications. The IEEE heterogeneous integration thermal roadmap states that new thermal interface material solutions must provide a path to the successful application of increased total-package die areas up to 100cm2. While GPU architectures are relatively isothermal during usage, CPU hotspots in complex heterogeneously-integrated modules will need to be able to handle heat flux hotspots up to 1000W/cm2 within the next two years. Indium and its alloys are used as reflowed sTIMs in both CPU and GPU “die to lid/heat spreader” (TIM1) applications. Their high bulk thermal conductivity and proven long-term reliability suit them well for extreme thermomechanical stresses.

In this webinar, Mayberry will present on the effects of reflow methodology, solder flux type/fluxless processing, and preform design parameters, such as alloy type. Data will be provided on various reflow processes including pressure (autoclave) and vacuum reflow of sTIMs, which is becoming necessary to meet upcoming requirements for ultra-low voiding. The use of sTIMs in the context of alternative TIM applications and technologies, such as thermal greases, pads, and phase change materials, as well as liquid metals, will also be considered.
