Chip carrier with terminating resistive elements |
摘要 |
A generic chip carrier is described which includes, as integral parts, a voltage bus and a plurality of terminating resistors connected between the voltage bus and signal traces on the carrier. The voltage bus wraps around the chip carrier, thus providing a large area of metal. Through the selective use of the terminating resistors, the generic carrier can be customized for a particular type of integrated circuit, i.e., source or destination termination of signals. A signal trace may be customized by "operating" the terminating resistor with a current spike applied by a standard electrical probe. Spare bonding pads and terminating resistors are placed at intervals about the periphery of the carrier as insurance against defective or mistakenly removed terminating resistors.
