Monitoring of resistor manufacture by anodic process - has resistor in test bridge network and electrolytic circuit with anti:synchronised switches

摘要

The circuit tests resistors during layering. The resistor under test is connected as the anode in the deposition circuit and alternately measured against a standard value in the test circuit. The layers are formed by anodic oxidation. The test circuit consists of a bridge network with a standard resistance in one arm and the resistor being manufactured in the other, opposite a cathode (K) in an electrolyte. The DC supply to the bridge is via a switch (r1) which is synchronised to open when another switch closes. The other switch controls the electrolytic process.
