PWM Series – PCB Wet-Chemical Desmear
Desmear machines of the PWM Series completely remove smear in the holes resulting from drilling and roughening. Our desmear equipment disposes of a horizontal conveyor system and comprises following process steps: loading and unloading, swelling, rinsing, desmear, pre-neutralizing and neutralizing, as well as drying. The PWM Series is well combinable with plating through-hole processes.
FEATURES
- Very good process results for through-holes and blind holes
- Excellent Mn6+ activation
- 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 low 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 processes to improve tank turnover rate by 50 %
