Fronius www.fronius.com (810) 220-4414 Reflow Soldering System’s Fans Help Reduce Operating Costs The Hotflow 4/26 reflow soldering system offers a process length of more than 5 m split into 26 heating zones and 4 cooling zones. The energy-saving system has fan motors that reduce power consumption and a system that reduces consumption of N2 by 20%. A shorter reflow system, the Hotflow 4/08, is also available. The Ecoselect 4, a stand-alone soldering system developed for midsized production volumes, can be loaded/unloaded manually or by transfer to a following system. The Ecocell, useful for larger batch sizes, features a dip module and multinozzles. It is equipped with two solder baths and supports product changes. Kurtz Ersa www.ersa.com (800) 363-3772 Liquid Flux Leaves Low Postprocess Residues NC277 is a VOC-free liquid flux that is electrically safe as an alcohol-based flux and has a medium residue that is suitable for long thermal demands. The halide-free, environmentally safe liquid flux can withstand the high thermal preheats required for palletized selective soldering. Also, it provides a broad activation range, proving to be a good flux for a variety of process parameters and applications, including lead-free wave soldering with tin-silver-copper, tin-silver, tin-copper, and other alloys. In addition, the liquid flux offers low postprocess residues and passes the IPC SIR 2.6.3.7 test in an air-dried state.
