Abstract
A tester apparatus is described. Various components contribute to the functionality of the tester apparatus, including an insertion and removal apparatus, thermal posts, independent gimbaling, the inclusion of a photo detector, a combination of thermal control methods, a detect circuitry in a socket lid, through posts with stand-offs, and a voltage retargeting.
Claims9
A cartridge comprising:
- a socket of insulative material and having upper and lower sides, a first formation on the upper side to hold a first electronic device, and a second formation on the upper side to hold a second electronic device;
- a lid;
- a first pusher plate rotatably mounted to the lid;
- a second pusher plate rotatably mounted to the lid, the lid being locatable over the socket and movable towards the socket, the rotatable mounting of the first pusher plate allowing for the first electronic device to rotate the first pusher plate relative to the lid and the rotatable mounting of the second pusher plate allowing the second electronic device to rotate the second pusher plate independently from the first pusher plate relative to the lid;
- a first set of contacts held in the socket to connect to the first electronic device;
- a first set of terminals connected to the first set of contacts;
- a second set of contacts held in the socket to connect to the second electronic device;
- and
- a second set of terminals connected to the second set of contacts.

A method of testing one or more electronic devices comprising:
- releasably holding a first electronic device in a first formation on an upper side of a socket of insulative material;
- releasably holding a second electronic device in a second formation on an upper side of the socket;
- locating a lid over the socket, the lid having a first pusher plate rotatably mounted to the lid and a second pusher plate rotatably mounted to the lid;
- moving the lid towards the socket, the rotatable mounting of the first pusher plate allowing for the first electronic device to rotate the first pusher plate relative to the lid and the rotatable mounting of the second pusher plate allowing the second electronic device to rotate the second pusher plate independently from the first pusher plate relative to the lid;
- and
- connecting the first and second electronic devices to an electric tester through an interface connected to the socket.
