(May 21, 2008) SPOKANE VALLEY, Wash. — ACE Production Technologies Inc. introduced a nitrogen peel-off jet that can improve fine-pitch selective soldering results. It is said to mitigate wettability and bridging issues that occur with lead-free solders in wave and selective soldering systems, especially with fine-pitch spacing.

Tight spaces, small gaps between adjacent components, and very-fine-pitch devices were cited as reasons for developing the jet, which is a version of the air-knife. The product provides a 360° directional jet of pre-heated nitrogen (N₂) to assist in minimizing solder accumulation on specific solder joints that, due to design or configuration, might be more susceptible to accumulation. By applying a jetted pulse of N₂ at a critical moment in the soldering process, users can achieve surface wetting with the minimal amount of solder required for a quality solder joint, according to ACE.
