Wave Height Monitor Enhances Process Stability for Precision Selective Soldering

ACE Production Technologies Inc. announces a breakthrough in precision solder wave control through the development and integration of a new wave height monitor and control module. This new control feature, according to ACE, can maintain solder wave heights to within +/- 0.005", which is critical when selectively soldering the smallest, tight pitch components in high volume automated production environments.

In making the announcement, Al Cable, President, said, “This new capability is particularly effective when working with the smallest wave nozzle sizes, under 6mm down to 1.5mm, and selectively soldering tight pitch component areas. When we combine this new wave height monitoring circuit with our precision nitrogen inerted solder delivery system and the availability of a nitrogen air-knife, we now have all the tools needed to perform the most demanding selective soldering operations in a highly reliable, volume oriented production operation.”

According to Cable, the monitoring methodology incorporates resistive measurements of wave height relative to a known reference. This is performed at programmable intervals during extended production runs, and closed-loop feed-back is then used to automatically adjust solder pump speeds and therefore wave heights.
