ACE Production Technologies announces the addition of Nitrogen (N2) Spot Pre-Heating capability to their popular KISS line of Selective Soldering machines. N2 Spot Pre-Heating joins a group of special application features available for KISS machines, which range from semi-automated to fully automated in-line capable selective soldering production systems.

The N2 Spot Pre-Heater makes it possible to focus and control superheated nitrogen delivery to a very small user-defined area of an electronics assembly to be selectively soldered.

This special N2 feature is appropriate for soldering operations where large area bottom-side or top-side pre-heating are not feasible or options, and in situations where extended pre-heat cycles and/or extended solder dwell times represent a danger to the subject component or adjacent components.

"We have engineered a method to proportionately control a number of critical parameters including ramp-to-temperature, volume of flow, and dwell time, creating a true small-area pre-heat profile" Al Cable, President of ACE, says. "The inclusion of a few necessary, integral controls and added programming to our already existing methods of using nitrogen within the system has made this possible" he added.

Using ACE's new N2 Spot Pre-Heat controls in conjunction with their nozzle and nitrogen cap design allows the user to program the delivery of the right amount of nitrogen, with the proper profile, through the solder nozzle before the solder can begin to flow.
