The KISS line of selective soldering equipment now includes a wave height monitor and control module. Reportedly maintains solder wave heights to within +/- 0.005". Is said to be effective when working with the wave nozzle sizes from 6 mm to 1.5 mm, and selectively soldering tight pitch component areas. Monitoring methodology incorporates resistive measurements of wave height relative to a known reference. Is performed at programmable intervals during extended production runs; closed-loop feedback is then used to automatically adjust solder pump speeds.
