Analysis of Electrical Properties the Sn-Bi and the Sn-Bi-Al as Environmentally Friendly Solder Material

Analysis of electrical properties the Sn-Bi and Sn-Bi-Al have been done. This research conducted to analysis the electrical properties for the Sn-Bi alloys with varied on Bi content and for the Sn-52Bi-Al alloys with varied on Al content. The measurement of electrical properties was conducted by LCR (inductance-capacitance-resistance) method. The results form measurement was compared to calculations. The Sn-Bi alloys showed increased in their specific electrical resistance from the alloy without Bi content to the alloy with 30 wt% of Bi, in the other hand at 52 wt% of Bi showed decreased in specific electrical resistance and increase at 70 wt% of Bi. The results showed increased in concentration of Al in alloys, the specific electrical resistance decreased.
