A method for testing System-In-Package (SIP) devices each having a plurality of electrical contacts is described. The method and apparatus utilizes industry standard JEDEC trays and tests at least a predetermined portion of all devices in such trays at the same time.

Method for testing system-in-package devices

Apparatus for testing System-In-Package (SIP) devices each having a plurality of electrical leads is described. The apparatus utilizes industry standard JEDEC trays and tests at least a predetermined portion of all devices in such trays at the same time. The apparatus comprises a test hive comprising: a plurality of test circuits corresponding in number to at least a predetermined number of cells in the tray; and a plurality of groups of test contacts, each group is coupled to one of the test circuits and is oriented to engage the plurality of electrical contacts of a SIP device disposed in a corresponding one of the cells. The test hive is operable to simultaneously, electrically test at least a predetermined number of the number of the SIP devices in each tray engaged by the hive without removing the SIP devices from the tray. The apparatus also includes a sorter automatically operable to remove each SIP device that did not pass electrical testing with SIP devices that did pass electrical testing until a tray of electrically tested SIP devices is fully populated with SIP devices that did pass electrical testing.

Apparatus for testing system-in-package devices

Apparatus for testing System-In-Package (SIP) devices each having a plurality of electrical contacts is described. The apparatus comprises a JEDEC standard tray receiving apparatus comprising a plurality of tray aligners to align the tray into a predetermined position to account for dimensional tolerances of the tray. The apparatus further comprises a test assembly proximate the tray receiving apparatus. The assembly comprises; a plurality of test circuits corresponding in number to the number of cells in the tray, a plurality of groups of test contacts, each of group of the test contacts being coupled to one of the test circuits and being oriented to engage a plurality of electrical contacts of a SIP device disposed in a corresponding one of the cell, the plurality of test circuits being operable to simultaneously, electrically test a predetermined number of SIP devices in a JEDEC standard tray engaged by the receiving apparatus without removing the SIP devices from the tray.

Apparatus for testing micro SD devices each having a plurality of electrical leads is described. The apparatus utilizes industry standard JEDEC trays and tests all devices in such trays at the same time. The apparatus comprises a test hive comprising: a plurality of test circuits corresponding in number to at least a predetermined number of cells in the tray; and a plurality of groups of test contacts, each group is coupled to one of the test circuits and is oriented to engage the plurality of electrical contacts of a micro SD device disposed in a corresponding one of the cells. The test hive is operable to simultaneously, electrically test at least a predetermined number of the number of the micro SD devices in each tray engaged by the hive without removing the micro SD devices that did pass electrical testing until a tray of electrically tested micro SD devices is fully populated with micro SD devices that did pass electrical testing.
