Abstract: The present invention relates to a pogo pin cooling system and a pogo pin cooling method and an electronic device testing apparatus having the system. The system mainly comprises a coolant circulation module, which includes a coolant supply channel communicated with an inlet of a chip socket and a coolant recovery channel communicated with an outlet of the chip socket. When an electronic device is accommodated in the chip socket, the coolant circulation module supplies a coolant into the chip socket through the coolant supply channel and the inlet, and the coolant passes through the pogo pins and then flows into the coolant recovery channel through the outlet.

Abstract: The diaphragm valve uses a metal dish-type diaphragm set to control the inflow and outflow of fluid. The metal dish-type diaphragm set is above an air flow channel to control the stem above the metal dish-type diaphragm set, and the air will be blocked by pressing the metal dish-type diaphragm to make it fit the metal valve base in the air flow channel; this non-metal valve base is fixed in the air flow channel by a fixed shrunk ring with a taper cross section, and the in-between metal diaphragm in the metal dish-type diaphragm set is annular in the center to reduce the metallic friction between metal diaphragms, to increase application times and to lower the leakage rate of the diaphragm valve.

Abstract: A non-contact pick-up device is disclosed. The non-contact pick-up device mainly includes a disk, and a plurality of air nozzles on the disk. Each nozzle has an air channel; and an upper end of the channel is tilt outwards. Therefore, as a disc-shaped article is placed on the disk; air jets out from the nozzles, due to Bernoulli principle, pressure difference is formed on the disc-shaped article. Thus, due to the action of atmosphere pressure, the disc-shaped article will be clamped. The pick-up device may be used in semiconductor manufacturing process for clamping a wafer.

Abstract: A multiple station CD-ROM testing system includes a conveyance device, a first gripping device, a multiple station testing device having a number of testing stations arranged in a vertically stacked fashion, a second gripping device, a collection device, and a controlling device comprised of a single programmable logic control and a single personal computer. The conveyance device carries the CD-ROMs fed into the system forward. The first gripping device picks up the CD-ROMs on the conveyance device and positions the CD-ROMs into the testing stations of the multiple station testing device to have the CD-ROMs tested therein by means of the controlling device and removes the tested CD-ROMs out of the multiple station testing device and places them back to the conveyance device. The second gripping device picks up the tested CD-ROMs on the conveyance device and transfers the tested CD-ROMs to either a next process if the CD-ROMs pass the test or a flaw product collection device if the CD-ROMs fail the test.
