Abstract
A testing apparatus has a load board and a device under test electrically interconnected with the load board. A pressure jig, which has a forcing unit and a structural member for fixing a fixed portion of the forcing unit with respect to the load board, also has a pressure actuating component moveable with respect to the fixed portion of the forcing unit. The pressure actuating component contacts the device under test. The apparatus may include a probe that contacts a terminal of the device under test for monitoring the signal state of the terminal as the device under test interacts with the load board.
Claims17
An apparatus comprising:
- a load board;
- a device under test electrically interconnected with the load board, the device under test having at least one terminal capable of being directly contacted by a probe of a measurement device;
- and
- a pressure jig comprising:
- a forcing unit;
- and
- a structural member configured to fix a fixed portion of the forcing unit with respect to the load board, the forcing unit having a pressure actuating component moveable with respect to the fixed portion of the forcing unit, the pressure actuating component contacting the device under test.
A method comprising:
- contacting a device under test with a pressure actuating component of a pressure jig;
- pressing the device under test towards a load board using the pressure actuating component;
- and
- while pressing, directly contacting at least one probe of a measurement device to at least one terminal of the device under test.
A method comprising:
- providing a load board;
- electrically interconnecting a device under test with the load board;
- fixing a fixed portion of a forcing unit with respect to the load board;
- contacting the device under test with a pressure actuating component of the forcing unit;
- forcing the device under test towards the load board using the pressure actuating component of the forcing unit;
- and
- directly contacting at least one probe of a measurement device to at least one terminal of the device under test thereby electrically coupling the at least one probe to the at least one terminal such that the at least one probe carries a signal representing the voltage level of the at least one terminal.
A method comprising:
- pressing the device under test towards a load board using a pressure jig;
- and
- while pressing, directly contacting at least one probe of a measurement device to at least one terminal of the device under test.
An apparatus comprising:
- a load board;
- a device under test electrically interconnected with the load board, the device under test having at least one terminal;
- a forcing unit;
- a horizontal structural member fixed with respect to the load board;
- and
- a vertical structural member fixed with respect to the load board, coupled to the horizontal member, and configured to fix a fixed portion of the forcing unit with respect to the load board, the forcing unit having a pressure actuating component moveable with respect to the fixed portion of the forcing unit, the pressure actuating component contacting the device under test.
