One of the steps in the preparation of printed circuit boards is their digestion. During this process, it is particularly important to maintain the correct temperature of the etchant and to ensure the circulation of liquids. Supervision of this process should be passed on to the appropriate electronic system, which will ensure the proper parameters of the bath. The system was designed without a microprocessor, based on popular, linear integrated circuits.

The device is especially recommended for electronics who prepare printed circuit boards themselves

Selected parameters:

• temperature control system of the pickling solution
• control of the grass pump circulation pump
• protection against too low level of the etchant in the tank
• operation status indication - LED diodes
• control elements - triacs, full galvanic separation
• possibility of making an additional relay control channel
• power supply - 230Vac
• printed circuit board and documentation included
