PCB spray etcherSpray technology delivers short etching times and reduces the amount of etchant required. This spray etcher has been specially developed for laboratory production and small series production. Up to eight eurocards can be processed in a single etching step. The development, rinsing and etching processes can be completed using one device. The work results can be adjusted precisely to the required parameters using the adjustable PCB holders, the infinitely adjustable heating element up to 45°C and the thermometer for the development and etching bath. The three drain valves enable the user to implement a clean work process. Max. PCB size: 200 x 380 mmEtching cuvette: approx. 3 lDevelopment cuvette: approx. 5 lRinsing cuvette: approx. 5 lChemicals required (not included in delivery):Sodium persulphate: approx. 0.75 kgDeveloper: approx. 50 gPackaging size: 620x 670x 450 mm
