PWT Series – PCB Wet-Chemical Surface Treatment

Equipment of the PWT Series is used for cleaning and roughening the copper surface to improve its bonding ability for following processes. The PWT Series combines horizontal processes and covers loading and unloading, brushing/cleaning, water and acid rinsing, micro-etching as well as drying.

FEATURES

  • Over 95 % modularized products
  • No dirt or residual chemicals after wet cleaning
  • High conveying stability with deviation of only ± 10 mm
  • Equipped with automatic control systems to ensure longest uptime

ADVANTAGES

  • Excellent squeeze roller design with drag-out of ≤ 10 cc/m² to prevent chemistry drag-out and contamination
  • Sloped-bottom tanks for chemical processed to minimize solution leftovers and load on wastewater treatment after rinsing
  • Sloped-bottom and small-volume tanks for rinsing processes to improve tank replacement rate by 50 %
