A design-for-testability methodology of network oriented diagnostic test for PCBs is proposed.The PCBs designed according to this methodology not only can realize self-inspection at power up but also can be controlled by remote terminal
such as PC
through wireless or cable network.The remote terminals can start circuit test
control test process
review test flow
obtain test results
renew/update test procedures.It provides a practical and effective approach for high quality test of PCBs.
