Seika's award-winning Solder Paste Recycling Unit enables approximately 90 percent of waste solder paste to be recovered as solder bar. The system provides a major decrease in disposal costs for factory waste, a reduction in CO2 emissions, and reduced costs for solder bar as a result of recycling waste. As an additional benefit, the recycling unit is fully automated with the use of a touch screen panel.
Seika also will feature the new Sawa Eco-Roll wiper roll cleaner that cleans rolls up to 24". The Sawa Eco-Roll eliminates waste and saves money by reusing wiper rolls for SMT printing machines. In addition to providing a reduction in waste, use of the wiper roll cleaner results in reduced CO2 emissions.
Wiper rolls are widely used for under stencil cleaning to wipe off solder paste in the SMT printing process. Most of them are used only once, then are disposed of with other solder waste. Recycling wiper rolls not only reduces emissions but also reduces lumber usage. In addition, tests have shown that repeated cleaning of wiper rolls does not compromise the performance when cleaning stencil apertures.
Also to be highlighted is the Sawa Ecobrid, a fully automatic low-VOC emission stencil cleaner. The cleaner provides up to a 66 percent reduction in CO2 emissions, as well as a huge reduction in running costs. Additionally, the system cleans and dries in just five minutes.
Sawa Stencil Cleaners are widely used in the Japanese electronics industry to ensure high yields when screen printing solder paste onto PCBs. Normal cloth wipe cleaning of stencils cannot completely remove solder paste especially in fine-pitch applications because a small amount of solder balls have a tendency to adhere to the corners of the apertures.
Product literature also will be distributed for all of Seika Machinery's products. For more information about Seika’s full product line, meet Tim Cappoen, Branch Manager & ATE Account Manager, at the SMTA Toronto Expo & Tech Forum or visit http://www.seikausa.com.
