PWP Series – PCB Wet-Chemical Electroless Copper Deposition

Equipment of the PWP Series guarantees an optimum deposition of electroless copper on the hole walls as basis for electrolytic copper plating. The integrated production line is well combinable with desmear process, disposes of a horizontal conveyor system and covers following process steps: loading and unloading, conditioning, micro-etching, pre-dip, activation, reduction, copper deposition as well as several rinsing and drying steps.

FEATURES

  • Very good process results for through-holes and blind holes
  • No dirt or residual chemicals after wet cleaning
  • High conveying stability with deviation of only ± 10 mm (with width control device)
  • Equipped with automatic control system to guarantee stable process parameters

ADVANTAGES

  • Over 95 % modularized products
  • Excellent squeeze roller design with drag-out of ≤ 10 cc/m² to prevent chemical drag-out and contamination
  • Sloped-bottom tanks for chemical processes to minimize solution leftover
  • Sloped-bottom and small-volume tanks for rinsing process to improve tank turnover rate by 50 %
