A Study on the Test Strategy of the Mounted Devices on the Electronic Circuit Board

Because the circuit board has the structure connected by circuit patterns, the work to test whether the analog devices or circuits such as resisters, capacitors, inductors, diodes, etc. on the tested board is goof or not is very difficult. This paper proposes the test method of identifing the faulted devices or faulted circuit on the circuit board using guarding circuit. The guarding method is the techniqus measuring accurately the value of the devices by separating the electronic devices to be tested from around it. Finally, the availability and accuracy of the proposed test method is verified by applying the technique to a test electronic circuit.
