Indium Corporation's Vice President of Technology, Dr. Ning-Cheng Lee, will present at the IPC APEX Expo technical conference on March 13-17 in Las Vegas, Nev.

Dr. Lee will give his presentation A Novel Solution for No-Clean Flux Not Fully Dried Under Component Terminations at the Flux Reliability technical session at 1:30 p.m. on March 16. He will talk about a new halogen-free no-clean SnAgCu solder paste that exhibits very good SIR and SMT assembly performance, including low QFN voiding and high HIP resistance.

Dr. Lee will also present High Reliability Performance and Mechanism of Pressureless Sintering of Nano-Ag Paste for Die-Attach during the Nano-Materials (for PCB Fabrication and Component Die-Attach) technical session at 10:30 a.m. on March 17. This presentation discusses a novel silver paste that has been developed without any polymeric inclusion for the pressureless sintering die-attach process. This new paste has been designed to address the challenges of service temperature, thermal conductivity, electrical conductivity, and reliability in die-attach for high-power devices such as IGBT.

Indium Corporation experts will also provide technical leadership for the following panels:

  • Eric Bastow, Assistant Technical Manager, will moderate the:
    • Solder Paste Development technical session
    • Flux Reliability I technical session
  • Brook Sandy-Smith, Technical Support Engineer for PCB Assembly Materials, will moderate the:
    • Flux Specifications Task Group – Standards Development committee meeting
    • Flux Reliability II technical session with speaker Eric Bastow

Indium Corporation will also conduct one-on-one meetings on how to Avoid the Void to achieve reliability, productivity, and satisfied customers. Experts will be at Indium Corporation's booth #3028 to discuss unique applications, provide insights, and answer questions From One Engineer To Another®
