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.



Seika also will debut the Seitec STS-2533SJ Soldering System, specially-designed for off-line and modular selective soldering. The programmable system features a special nozzle design and a spray fluxer unit, enabling flawless soldering of leads and pads. Additional features include a conveyor with roller, a specially-designed solder pot and a drawer-type solder pot. The Bravo ST-2533 from Seitec is the ideal soldering solution for mass production.



The STS-2533SJ features a CCD camera option that measures and compensates the solder flow height automatically by controlling the motor speed. The camera provide reliable soldering with stable solder temperature control (±1° @ 28°), a heated N2 supply, top and bottom pre-heating and drop jet fluxing. Additionally, with the CCD camera, there are no bridges and fewer voids, as well as improved tact time.
