Abstract
An apparatus for quickly and reliably aligning a semiconductor handling apparatus with a semiconductor tester. Two docking plates are attached, one to the device handler and one to the device tester. On the docking plates a substructure is mounted which first allows initial alignment of the handler plate with the test head plate after which the substructure provides the means of securely positioning and interlocking the handler plate with the test head.
Claims8
In combination with a testing system for testing electronic devices having an electronic device handler and a substantially heavy electronic test head, a system for positioning said electronic test head for docking and undocking with said electronic device handler, in combination with mechanical interfaces for attaching said system between said device handler and said test head, in combination with mechanical interfaces for attachment of said electronic devices to said system, said system comprising:
- a device handler plate;
- a device tester head plate;
- alignment devices for aligning said device handler plate with said device tester head plate, wherein the alignment devices for aligning said device handler plate with said device tester head plate comprises three alignment sockets mounted on said device handler plate and three alignment pins mounted on said device tester head plate where said alignment pins align with and fit into said alignment sockets, said alignment sockets are mounted in a first pattern on the surface of said device handler plate while said alignment pins are mounted on the surface of said tester head plate in a second pattern whereby said first pattern aligns with said second pattern, whereby furthermore said alignment sockets and said alignment pins are facing each other during alignment of said handler plate with said tester plate;
- and
- interlocking devices for interlocking said device handler plate with said tester head plate.
In combination with a testing system for testing electronic devices having an electronic device handler and a substantially heavy electronic test head, a system for positioning said electronic test head for docking and undocking with said electronic device handler, in combination with mechanical interfaces for attaching said system between said device handler and said test head, in combination with mechanical interfaces for attachment of said electronic devices to said system, said system comprising:
- a device handler plate;
- a device tester head plate;
- alignment devices for aligning said device handler plate with said device tester head plate;
- and
- interlocking devices for interlocking said device handler plate with said tester head plate, said interlocking devices for interlocking said device handler plate with said device tester head plate comprises three cam bearings mounted on said device handler plate and three alignment cams mounted on said device tester head plate where said cam bearings align with and interact with said alignment cams, said cam bearings being mounted in a first pattern on the surface of said device handler plate while said alignment cams are mounted on the surface of said test plate in a second pattern, whereby said second pattern aligns with said first pattern, while furthermore said cam bearings and a sloping edge of said alignment cams are in contact with each other during interlocking of said handler plate with said tester plate, said alignment cams being rotated by manual force and being allowed to rotate against said cam bearings thus urging said device handler plate toward said tester head plate.
In combination with a testing system for testing electronic devices having an electronic device handler and a substantially heavy electronic test head, a system for positioning said electronic test head for docking and undocking with said electronic device handler, in combination with mechanical interfaces for attaching said system between said device handler and said test head, in combination with mechanical interfaces for attachment of said electronic devices to said system, said system comprising:
- a device handler plate;
- a device tester head plate;
- alignment devices for aligning said device handler plate with said device tester head plate, said alignment devices for aligning said device handler plate with said tester head plate comprises four alignment sockets and four alignment pins where said alignment pins align with and fit into said alignment sockets, said alignment sockets being mounted in a first pattern on the surface of said handler plate while said alignment pins are arranged on said surface of said tester head plate in a second pattern whereby said first pattern aligns with said second pattern whereby furthermore said four alignment sockets and said four alignment pins are facing each other during alignment of said handler plate with said tester head plate;
- and
- interlocking devices for interlocking said device handler plate with said tester head plate.
In combination with a testing system for testing electronic devices having an electronic device handler and a substantially heavy electronic test head, a system for positioning said electronic test head for docking and undocking with said electronic device handler, in combination with mechanical interfaces for attaching said system between said device handler and said test head, in combination with mechanical interfaces for attachment of said electronic devices to said system, said system comprising:
- a device handler plate;
- a device tester head plate;
- alignment devices for aligning said device handler plate with said device tester head plate;
- and
- interlocking devices for interlocking said device handler plate with said tester head plate, said interlocking devices for interlocking said device handler plate with said device tester plate comprises four cam bearings mounted on said device handler plate and four alignment cams mounted on said device tester head plate where said cam bearings align with and interact with said alignment cams, said cam bearings being arranged in a first pattern on the surface of said handler plate while said alignment cams are arranged on said surface of said tester head plate in a second pattern that aligns with said first pattern, while furthermore said cam bearings and a sloping edge of said alignment cams are in contact with each other during interlocking of said handler plate with said tester plate, said alignment cams being rotated by manual force and being allowed to rotate against said cam bearings thus urging said handler plate toward said tester plate.
In combination with a testing system for testing electronic devices having an electronic device handler and a substantially heavy electronic test head, a system for positioning said electronic test head for docking and undocking with said electronic device handler, in combination with mechanical interfaces for the attachment of said system to said device handler and to said test head, in combination with mechanical interfaces for attachment of said electronic devices to said system, said system comprising:
- A handler plate having a large cutout allowing physical access to said tester having four corners;
- four alignment sockets, one alignment socket mounted in each of said four corners of said handler plate;
