Abstract

The invention provides a probe card comprising a printed circuit board, a power supply / signal conductor sheet, a grounding conductor sheet, an insulator, an electronic circuit, a power supply / signal probe and a grounding probe. The power supply / signal conductor sheet is electrically connected with a power supply or a signal. The grounding conductor sheet is electrically connected with a grounding potential. The insulator is arranged between the power supply / signal conductor sheet and the grounding conductor sheet. The electronic circuit is electrically connected with the power supply / signal conductor sheet and the grounding conductor sheet. The power supply / signal probe is electrically connected with the power supply / signal conductor sheet and the power supply / signal probe is directly or indirectly connected with the printed circuit board and is used for in point contact a grounding contact of an object to be measured. The grounding conductor sheet is arranged between the printed circuit board and the grounding probe. The probe card is capable of providing enough space, so that the electronic circuit can be fully installed without limited to the finite space on the printed circuit board.

Description

technical field [0001] The present invention relates to a probe card, and in particular to a cantilever type probe card. Background technique [0002] The main purpose of the probe card is to directly contact the pads or bumps on the object under test (such as a chip) through its probes, and cooperate with the peripheral test machine and software control to achieve the purpose of automatic measurement and further screen To produce defective products, the test signal is usually sent through the test machine, and then sent to the object under test through the probe card, and then the test result signal is sent back by the object under test, and then analyzed by the probe card to the test instrument. [0003] The probe card has a precise contact mechanism to test the circuit on the chip and perform electrical testing operations to ensure that the electrical characteristics and performance of the chip are manufactured according to the design specifications. When testing, it is ...
