Temperature Controlled & Hermetically Sealed Nitrogen Process Tunnel 

 

Full nitrogen tunnel machines offer optimal process conditions for a lead free wave soldering process. Critical for the process quality is the oxygen ppm level in the tunnel. Generally, the lower this ppm level is, the better the solderability can be realized. In an environment with a low oxygen ppm level, oxidation of materials such as the solder, lands and leads, is kept to a minimum thereby allowing for improved solderability. This is especially critical in a lead free application. The wetting characteristics of lead free alloys are more difficult and the higher process temperatures generally lead to increased oxidation. A significant additional advantage of a full nitrogen tunnel machine is the improved thermal efficiency. The hermetically sealed tunnel prevents heat escape and thereby greatly reduces the energy required for the pre-heating modules when compared to non-tunnel machines.  Finally, the innovative POWERFLOW N2 full tunnel was specifically designed to realize running cost savings as much as 90 % when compared to conventional wave solder machines.
