WebSAC is about 217oC, or approximately 34oC higher than Sn/Pb, which has a melting point of 183 oC. For proper wetting and solder joint formation with Sn/Pb solder, it is common to see peak reflow temperatures of 230-235oC, or about 43-48oC above the melting point. Assuming a similar temperature above melting is required for SAC, this implies Web1. Experiments are divided into two groups. Group #1 will do test tube #1 (mixtures 1-4). Group #2 will do test tube #2 (mixtures 5-8). Tube #1 should contain 17g of naphthalene and tube #2 should contain 18g of biphenyl.
