CONTACT SOCKET MODULE AND METHOD OF TESTING ELECTRONIC COMPONENTS USING A CONTACT SOCKET MODULE
A contact socket module for use in an automated test equipment (ATE) for testing electronic components (DUTs) being carried by a carrier comprises: a plurality of groups of spring contacts, wherein each spring contact comprises a DUT sided contact tip, a retracting plate being moveable, and a controller controlling the movement of the retracting plate, wherein the retracting plate and the spring contacts act mechanically on each other. In a first position the DUT sided contact tips are adapted to contact to contact portions of the electronic components, and in a second position, the DUT sided contact tips are adapted to release the contact to the contact portions of the electronic components.
TEST CARRIER AND ELECTRONIC COMPONENT TESTING APPARATUS
A test carrier that accommodates a DUT and includes a first flow passage through which fluid supplied from an outside of the test carrier flows.
Probing system for discrete wafer
The present invention provides a probing system, which utilizes a suction nozzle to suck a wafer in probing. A relative distance between the suction nozzle and the probes can be adjusted according the conditions of the probing system, so the system extends the usage life.
A probe-holder support and corresponding probes with facilitated mounting
A contact probe for electronic tests includes an upper part having an end portion for contacting a first electronic component; a lower part having an end for contacting a second electronic component; and an elongated and deformable central body interposed between the upper and lower parts. The lower part has an enlarged head with a lower surface intended to rest at least partially onto a horizontal surface, the lower surface having an inclination angle from the horizontal surface onto which it rests when the probe is unbuckled and, when the probe is buckled, it can assume a position in which the lower surface moves to rest entirely onto the horizontal surface, thereby eliminating the inclination angle.
Semiconductor inspecting method
The semiconductor inspecting method includes following steps. First, a first position of a probe needle from above is defined by adopting a vision system of a semiconductor inspecting system. Then, a first relative vertical movement between the probe needle and the pad is made by adopting a driving system of the semiconductor inspecting system. Thereafter, a minimum change in position of the probe needle corresponding to the first position is recognized by adopting the vision system of the semiconductor inspecting system. Next, the first relative vertical movement is stopped by adopting the driving system of the semiconductor inspecting system.
Test head assembly for semiconductor device
A test head assembly for a semiconductor device has a carrier, a pin seat and a test wire assembly. The carrier is formed in an L shape and has a lateral board, a perpendicular board and a opening formed through the perpendicular board. The pin seat is mounted in the corresponding opening. The test wire assembly has a test head, a plurality of connectors and a plurality of test wires. The test head is mounted on an outer sidewall of the lateral board and connected to the pin seat through the test wires and the connectors. Therefore, the pin seat is mounted on the perpendicular board of the L-shaped uprightly and the test head is mounted on the lateral board. The pin seat and the test head are not parallel to each other, and a lateral size of the test head assembly is reduced to increase the space usage.
