Etching unit for PCB with heating BB4.3

Etching equipment with heating suitable for PCB prototyping.
The format for etching PCBs is 200 x 300 mm - single or double-sided etching.
For BB4.3, the average etching time for a new liquid at 25 °C is 6 to 7 minutes. The etching time varies depending on the type of medium used and the temperature. Activated ferric chloride has a higher etching capability than ammonium persulfate and does not crystallize, it is recommended.

- High quality PVC construction
- Ideal for laboratories
- For use with ferric chloride or ammonium persulfate.
- PCB fixed with PVC holder
- Small tank volume, 3.25 litres
- Accelerated etching due to bubbles.
- Includes diaphragm pump.
