Abstract:
An automated testing system for testing integrated circuit devices having conductive pins, at least some of the pins being for electrical signals to be provided to and/or from the devices, the system comprising:a conveyor for providing a device to a testing location; electrical conductors brought into and out of contact with at least some of the pins of the device while the device is held at the testing location, the electrical conductors being used to provide input signals to at least one pin and for receiving output signals from at least one pin; and a magnetic circuit including at least one coil for controllably providing a magnetic field with known magnitude to the device while the device is at the testing location, the electrical conductors providing a signal from the device in response to the device sensing the magnetic field, electrical testing and magnetic field testing being performed on the device while the device is at one testing location.
