Abstract:
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.

Abstract:
An apparatus is described for detecting particulates on or defects in a transparent media. The apparatus includes a light source, and an array of light-sensitive elements, each of which produce an electrical signal indicating a characteristic value based on light incident on the element. The first array is disposed a predetermined distance from the at least one light source so that the transparent media may be placed between the light source and the array. An addressing circuit reads the characteristic values produced by each element, and an analog-to-digital converter circuit digitizes the characteristic values, producing digitized values. A processor processes the digitized values to determine whether a particle or defect is present at least based on a position of the shadow cast by the particle or defect on the array. A method for detecting a particulate or defect on or in a transparent media is also described.
Abstract:
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.
