Green Paste is said to help eliminate cross-contamination between leaded and Pb-free boards in a mixed production environment. Is visually green, permitting operators to distinguish it from gray-colored SnPb paste. Color remains until reflowed, leaving normal metallic joint appearance. Residues are clear, but fluoresce under black light. Available in SAC 305, Sn100e for no-clean and water-soluble flux types, and others.

A radio frequency version of the Explorer thermal profiler beams profile data in real-time to the computer, as the profiler runs through the reflow oven or wave solder machine. Instantly shows what is going on with the process. There is said to be less potential stress to the profiler or production board; any over-temp situation is instantly revealed. Alerts operator to such pitfalls as forgetting to turn on prior to a run; when a TC pops off; wrong oven recipe, and when profiler gets stuck in the oven tunnel.
