摘要： A testing apparatus with reduced warping of the probe card and a method of reducing warping of a probe card of a testing apparatus are disclosed. The testing apparatus can include a testing head and a platform opposite the testing head, where the testing head and platform move relative to one another to bring a sample into contact with probing tips of the testing apparatus. The testing head can include a probe card printed circuit board, a stiffener, a discontinuous backer and a plurality of probing tips. The stiffener can be coupled to and reinforcing the probe card. The discontinuous backer can extend from the probe card to the stiffener, and can include at least one unfilled void extending from the stiffener to the probe card. The plurality of probing tips can extend from a distal end of the testing head.

摘要： A circuit is disclosed that includes a signal-forcing path, a discharging path, a contact probe, a monitoring probe and a switch module. The signal-forcing path is connected to a signal source. The discharging path is connected to a discharging voltage terminal. The contact probe contacts a pad module of an under-test device. The monitoring probe generates a monitored voltage associated with the pad module. The switch module is operated in a discharging mode to connect the contact probe to the discharging path when the monitored voltage does not reach a threshold voltage such that the under-test device is discharged and is operated in an operation mode to connect the contact probe to the signal-forcing path when the monitored voltage reaches the threshold voltage such that a signal generated by the signal source is forced to the under-test device.

摘要： A method is disclosed that includes the operations outlined below. For a plurality of dies on a test fixture, an antenna distance between each of first antennas of one of the dies and every one of first antennas of the other dies is determined. The dies are categorized into die groups, wherein the antenna distance between each of the first antennas of one of the dies in one of the die groups and every one of the first antennas of the other dies in the same one of the die groups is larger than an interference threshold. Test processes are sequentially performed on the die groups. Each of the test processes is performed according to signal transmissions between the first antennas and second antennas of the under-test device each positionally corresponds to one of the first antennas.

摘要： A method that is disclosed that includes the operations outlined below. Dies are arranged on a test fixture, and each of the dies includes first antennas and at least one via array, wherein the at least one via array is formed between at least two of the first antennas to separate the first antennas. By the first antennas of the dies, test processes are sequentially performed on an under-test device including second antennas that positionally correspond to the first antennas, according to signal transmissions between the first antennas and the second antennas.

摘要： The present disclosure provides a system and method for providing electrostatic discharge protection. A probe card assembly is provided which is electrically connected to a plurality of input/output channels. The probe card assembly can be contacted with a secondary assembly having an interposer electrically connected to one or more wafers each wafer having a device under test. Voltage can be forced on ones of the plural input/output channels of the probe card assembly to slowly dissipate charges resident on the wafer to thereby provide electrostatic discharge protection. A socket assembly adaptable to accept a 3DIC package is also provided, the assembly having a loadboard assembly electrically connected to a plurality of input/output channels. Once the 3DIC package is placed within the socket assembly, voltage is forced on ones of the input/output channels to slowly dissipate charges resident on the 3DIC package to thereby provide electrostatic discharge protection.
