Abstract

This project is a study of interaction between tin-lead solder with gold that associated with intermetallic compound IMC. Alloy Sn63Pb37 solder is used as a control for the experiment. Effect of IMC formation to joint reliability is studied by varying the gold thickness through pre-tinning process. A rough guide of implementation to prevent gold embrittlement to Sn63Pb37 solder is given at the end of the research. Physical analysis equipment X-ray fluorescence (XRF) and high power optical scope for IMC microstructure investigation are utilized. It is found out in this study that the time of pre-tinning process where the pins are submerge into solder bath contribute to the magnitude of IMC formation.
