| titleOfInvention | Circuit for the detection of solder-joint failures in a digital electronic package |
| abstract | The solder-joint integrity of digital electronic packages, such as FPGAs or microcontrollers that have internally connected input/output buffers, is evaluated by applying a time-varying voltage through one or more solder-joint networks to charge a charge-storage component. Each network includes an I/O buffer on the die in the package and a solder-joint connection, typically one or more such connections inside the package and between the package and a board. The time constant for charging the component is proportional to the resistance of the solder-joint network, hence the voltage across the charge-storage component is a measurement of the integrity of the solder-joint network. |
