The Speedline UltraFill lead-free nozzles help to overcome a variety of process challenges inherent in lead-free wave soldering. The tools feature an innovative design, and are 40% wider than traditional tin-lead versions. This increases contact length and dwell time, and the nozzles are also placed closer together to reduce the temperature drop between them, so that less heat is needed to reflow solder joints in the second wave. The result is better hole fill without requiring a slowing of the conveyor, while reducing bridging defects and dross generation. A nitrogen covering is available as an option, and allows for either air or nitrogen operation, as determined by the recipe, without the need to change nozzles. The hood both covers the nozzles and the dross in the solder pot. Applications have shown that nozzles enhance both product quality and process performance – ranging from the elimination of the need for touch-up of poor hole fills to dramatic reductions in bridges/solder shorts. The UltraFill nozzles are available as an option on the Vectra and Electra wave soldering systems or as an upgrade to installed equipment. The nozzles are compatible with the Omega wave and the debridging Airknife.
