Probe card assembly
TL;DR: In this paper, a probe card assembly consisting of a stiffener ring combining with an upper printed circuit board and a lower printed circuit boards is described, where a plurality of coaxial transmitters are installed in the stiffener rings, and connect to the upper and lower printed circuits by cable connectors.
Patent
Modularized probe card for high frequency probing
TL;DR: In this paper, a modularized probe head for high frequency probing is presented, which includes a probe head, a mounting board and an interposer between the probe head and the mounting board.
Patent
Modularized probe head
TL;DR: In this article, a modularized probe head for modularly assembling on a probe card is configured for probing a semiconductor wafer under test, which includes a silicon substrate having an active surface and an opposing back surface.
Patent
Electronic device with a warped spring connector
TL;DR: In this article, the warped spring connector is disposed on the substrate and is connected to the bonding pad, and the coefficient of thermal expansion of the transmitting lead is different from that of the dielectric layer or the ground lead such that the warped-spring connector has a suspending end suspending away from the substrate.
Patent
Modular probe card assembly
TL;DR: A modular probe card assembly as discussed by the authors comprises a silicon substrate with probes modularly assembled on a main board, at least a socket is installed around silicon substrate and electrically connects to probe needles by a flexible printed wiring film.
