PWP Series – PCB Wet-Chemical Black-Hole Process
Equipment of the PWP Series for the black-hole process (direct metallization) deposits conductive carbon on the hole walls as basis for electrolytic copper plating. Our integrated black-hole machines are well combinable with desmear process, dispose of a horizontal conveyor system and cover following process steps: loading and unloading, cleaning/conditioning, multiple rinsing and drying steps, black-hole process as well as micro-etching.
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 %
