| 摘要 |
The present invention presents an electrostatic discharge and power surge protected circuit board (10) and method for providing an electrostatic discharge and power surge protected circuit board. The protected circuit board (10) includes temperature sensitive conducting material (14) and semiconductor circuit components (12). The temperature sensitive conducting material (14) has a critical current density, provides a high impedance when the critical current density is exceeded, and preferably comprises a high temperature superconductor. Preferably, the temperature sensitive conducting material (14) and the semiconductor circuit components (12) are coupled in series. In a method aspect of the present invention, an electrostatic discharge protected circuit board (10) is provided by providing a current carrying mechanism (16) on the circuit board (10), and coupling the current carrying mechanism (16) to temperature sensitive conducting material (14). Preferably, the temperature sensitive conducting material (14) is a high temperature superconductor, such as yttrium barium copper oxide.
