Direct contact type probe card

Abstract

The present invention relates to a direct contact type probe card which is a double-plate probe card, wherein the probe card comprises the following components: a main PCB which is of a disc shape, is formed with a quadrilateral opening at the central part and is formed with FPCB contact tables on two side surfaces; a plate which is a square component formed by steel and is connected with the bottom central part of the main PCB; a plurality of probe blocks which are arranged with a plurality of probes on the upper ends of the probe blocks and are fixedly equipped on the plate and projects from the upper surface of the main PCB; an FPCB which is formed with a probe contact table on one end and is formed with a PCB contact table corresponding with the FPCB contact table of the main PCB; FPCB blocks which are respectively provided at the side surface of each probe block and has an upper surface fixedly adhibited with the probe contact table of the FPCB; and an extrusion which is used for squeezing the PCB contact platform of the FPCB and the FPCB contact platform of the main PCB. The direct contact type probe card of the invention can simplify the structure and cancel the wiring and welding position for relatively reducing the incidence of undesirable phenomena and shortening the manufacturing time.

Description

technical field [0001] The present invention relates to a direct contact probe card (direct contact probe card), in particular to a flexible printed circuit board (FPCB) respectively forming a needle block (Needle block) and an FBCB formed with a probe contacting the needle block. ) block, which is then combined with a separate board, and a direct-contact probe card that combines the board with a printed circuit board (PCB). Background technique [0002] Probe cards are used in testing operations to confirm the quality of semiconductor devices. Recently, since semiconductor elements are packaged in various forms, probe cards are also designed in various forms according to the packaging forms of semiconductor elements to be tested. [0003] figure 1 A schematic plan view showing a conventional single-board probe card (Needle Probe Card) 10 . Generally, the probe card 10 includes: a probe fixing substrate 12 such as a PCB substrate or an Al substrate; a plurality of probes ...
