Time has passed however, and this exemption won't last forever. Engineers want to be prepared and begin testing the replacement materials which have been developed over the past few years. Unfortunately, therestill isn't an industry accepted material available.
Creating new solder alloys is not easy andIndium's Dr. Andy Mackie explains why in his recent blog posting titled, "Elementary, My Dear Watson…"
