Nitrogen Nozzles Deliver Lead-free Soldering Solution
February 22, 2005 |Estimated reading time: Less than a minute
FRANKLIN, Mass. — Speedline Technologies has introduced its new UltraFill lead-free nozzles, which are designed to enable electronic manufacturers to overcome a variety of process challenges inherent in lead-free wave soldering.
The nozzles are 40% wider than traditional tin/lead nozzles to increase contact length and dwell time, and are also placed closer together to reduce the temperature drop between the nozzles—so that less heat is needed to reflow solder joints in the second wave. As a result, the nozzles deliver hole fill without requiring a slowing of the conveyor, while reducing bridge defects and dross production. A nitrogen shroud is available as an option, allowing for either air or nitrogen operation without the need to change nozzles. The shroud both encompasses the nozzles in the pot and contains the dross in the solder pot, and lifts for maintenance and dedrossing without nozzle removal.
The nozzles are available as an option on the Vectra and Electra wave-soldering systems, or as an upgrade to existing, installed equipment. The nozzles are also compatible with the Omega wave and the Debridging Airknife.
