Plasma System Simplifies Roll-to-Roll PCB Treatment

The RollVIA, a completely self-contained vacuum plasma system with production-proven roll-to-roll material handling for printed circuit board (PCB) manufacturing environments, incorporates unique vacuum and gas flow technology. It also features new electrode designs and advanced temperature management with precise control of roll speed, tension, and edge guidance for uniform plasma treatment in surface activation, desmear, and etchback applications of substrates as thin as 25 microns. The RollVIA is said to be the only roll-to-roll plasma treatment system where the vacuum system, plasma chamber, control electronics, and 40 kHz power supply are housed in a single enclosure. The system measures 2,030 mm x 2,032 mm x 2,428 mm with an integrated pump package. It is available in three models to meet a variety of customer processing speed and throughput requirements and accommodates web widths up to 500 mm. Each configuration incorporates features such as precision temperature management, efficient gas use, and a fast vacuum pump. An optically-based edge guide detection system ensures reliable control during rewind operations. Nordson MARCH, Concord, CA. (925) 827-1240.
