EVS International worked with the global marketplace to gain invaluable feedback from which to develop solder dross recovery solutions that satisfy the high standards required from a modern manufacturing environment — particularly with regard to reliability, ease of operation, maintenance and environmental management. The new EVS 9000 is a culmination of this process and offers manufacturers solutions for all of these issues with reduced footprint, advanced electronic controls and integrated diagnostics.
The EVS 9000 offers a capacity of 20 kg/40 lb, and has the ability for single operation de-drossing of even the largest wave soldering machines. Its integrated hopper makes rapid transfer of dross both simpler and safer, and speeds de-drossing times by up to 70 percent. This provides a cleaner wave with less maintenance, less downtime and a reduction in shorts and bridging, as well as the potential to discontinue the use of messy wave oils and/or dross reduction powders.
The process uses heat and pressure inside a magnetized cylinder to separate and return pure solder into an ingot tray. The remainder of the material is automatically ejected down a sealed chute into a dross bucket. Hundreds of solder assays prove that the recovered pure solder is exactly the same specification as the solder in the WSM pot. This has been authenticated by the solder manufacturers and confirmed by the International Tin Research Institute. EVS International supports its product through 24-hour availability of spares and service and by partnering with quality distributors who have trained technicians and comprehensive spares stockholding.
The system offers the benefit of a rapid return on investment by recovering 50-70 percent pure solder from dross, with savings of up to 50 percent in solder costs. It will reduce dross off site by up to 70 percent, while reducing de-drossing time by up to 70 percent. The system provides a self-contained process to reduce the handling of dross and uses no chemicals or additives. The EVS 9000 will help a company to attain and retain ISO14001 accreditation; with the added benefit of improving wave solder machine effectiveness. These new solution follows on the heels of EVS International’s highly successful EVS 1000, which gained global approval with multiple industry awards, including “Product of the Year” at the most recent Productronica.
EVS Director, Simon Norman adds, “As manufacturers increasingly feel the effects of the current economic downturn, more and more companies will be looking at EVS Solder Recovery Systems as a highly effective way of reducing costs.”
Premiering in 2008, the NPI Awards program is an annual celebration of product excellence in electronics surface mount assembly. Premier products based on the finest examples of creative advancement in technology are chosen by a distinguished panel of industry experts.
