Abstract
A double sided primed circuit board is shown wherein one side is etched for receiving a plurality of surface mounted components constituting a control circuit. In one embodiment the control circuit provides for regulating the operation of a plurality to the beverage dispensing valves. An op-amp monitors the conductor for sensing the operation of the beverage dispensing valves as a function of a voltage drop there across. The conductor operates as a resistor, and any heating thereof that occurs as a result of the operation of the beverage dispensing valves is dissipated over the entire surface area of the circuit board. The control circuit also operates a dump valve for periodically dumping beverage if any of the valves have not been operated for a set period of time. The control circuit deactivates the operation of the dump valve during any sensed operation of one of the beverage dispense valves.
