Indium Corporation’s Sze Pei Lim, technical manager - Southeast Asia; and Sehar Samiappan, area technical manager, will present at the IPC Southeast Asia High Reliability Conference on August 20 in Penang, Malaysia.
Sze Pei Lim will present Alloy and Process Optimization for Low-Ag Solders, which reviews the critical challenges associated with SAC305 solder alloy, including high processing temperatures, high cost and price volatility, and poor resistance to mechanical shock. She will also discuss how doped low-Ag alloys can be used as a drop-in replacement to SAC305 with cost and reliability advantages.
Sehar Samiappan will present Effect of Reflow Profiling on the Electrical Reliability of No-Clean Solder Paste Flux Residues. This presentation discusses an experiment that studied the effect of reflow profiling on the electrical reliability of no-clean flux residues that can be measured using IPC J-STD-004[1] surface insulation resistance (SIR) testing. Both a halogen-free (ROL0) and a halogen-containing (ROL1) Pb-free no-clean solder paste, exposed to various reflow profiles, were used.
The IPC Southeast Asia High Reliability Conference is a one-day event featuring practical methodologies that can be deployed today. Industry experts representing every market sector will discuss solder technology, cleaning, test, and inspection strategies. For more information, visit www.ipc.org.
