Self-aligning docking system for electronic device testing
View Patent ↗A system for docking a device handler for an electrical device with a test head includes providing a device handler for holding the electrical device, the device handler having a plurality of docking pins. A test head having a plurality of docking modules mounted thereon is provided. The plurality of docking pins is aligned with the plurality of docking modules. The plurality of docking pins is inserted into the plurality of docking modules. The plurality of docking pins is secured in the plurality of docking modules in a docked position to connect the device handler to the test head.
1. A method for docking a device handler for an electrical device with a test head, comprising:
providing a device handler for holding the electrical device, the device handler having a plurality of docking pins;
providing a test head having a plurality of docking modules mounted comprises:
providing a plurality of docking modules having a collet for grasping the docking pin; and
providing a means for collapsing the collet around the docking pin;
aligning the plurality of docking pins with the plurality of docking modules;
inserting the plurality of docking pins into the plurality of docking modules; and
securing the plurality of docking pins in the plurality of docking modules in a docked position to connect the device handler to the test head.
2. The method as claimed in claim 1 , wherein:
providing a device handler having a plurality of docking pins provides a plurality of docking pins having a pilot diameter and a locating diameter; and
inserting the plurality of docking pins into the plurality of docking modules, further comprises:
inserting the pilot diameter of the plurality of docking pins into the plurality of docking modules to position the device handler with respect to the test head; and
inserting the locating diameter of the plurality of docking pins into the plurality of docking modules; and
securing the plurality of docking pins in the plurality of docking modules in a docked position secures the pilot diameter of the plurality of docking pins.
3. The method as claimed in claim 1 , wherein:
providing a device handler having a plurality of docking pins, further comprises:
providing a main handler plate;
providing a plurality of pitching plates positioned in the main handler plate; and
attaching the plurality of docking pins to the plurality of pitching plates.
4. The method as claimed in claim 1 , wherein:
securing the plurality of docking pins in the plurality of docking modules in a docked position further comprises:
substantially simultaneously securing the plurality of docking pins in the plurality of docking modules.
5. A method for docking a device handler for an electrical device with a test head, comprising:
providing a main handler plate having a handler electrical contact for holding the electrical device;
providing a plurality of pitching plates attached to the main handler plate;
attaching a plurality of docking pins to the plurality of pitching plates;
providing a test head having a test head electrical contact that connects to the handler electrical contact comprises:
providing a plurality of docking modules having a collet for grasping the docking pin; and
providing a means for collapsing the collet around the docking pin;
attaching a plurality of docking modules to the test head;
aligning the plurality of docking pins with the plurality of docking modules;
inserting the plurality of docking pins into the plurality of docking modules whereby the handler electrical contact connects to the test head electrical contact; and
securing the plurality of docking pins in the plurality of docking modules in a docked position to connect the device handler to the test head.
6. The method as claimed in claim 5 , wherein:
attaching a plurality of docking pins to the plurality of pitching plates attaches a plurality of docking pins having a pilot diameter and a locating diameter; and
inserting the plurality of docking pins into the plurality of docking modules, further comprises:
inserting the pilot diameter of the plurality of docking pins into the plurality of docking modules to position the device handler with respect to the test head; and
inserting the locating diameter of the plurality of docking pins into the plurality of docking modules; and
securing the plurality of docking pins in the plurality of docking modules in a docked position secures the pilot diameter of the plurality of docking pins.
7. The method as claimed in claim 5 , wherein:
providing a plurality of pitching plates attached to the device handler provides a plurality of pitching plates having a plurality of pitching holes, wherein:
associated ones of the plurality of pitching holes in a group of pitching plates define a set-up location for the plurality of docking pins.
8. The method as claimed in claim 5 , wherein:
securing the plurality of docking pins in the plurality of docking modules in a docked position further comprises:
substantially simultaneously securing the plurality of docking pins in the plurality of docking modules.
