Abstract

The embodiment of the invention discloses a flexible connection cable structure, a preparation method and a brain electrode device, the flexible connection cable structure comprises a sacrificial layer, a first insulating layer arranged on the sacrificial layer and comprising a first to-be-wired area, a first metal layer arranged on the first to-be-wired area and a first connection bonding pad, and the first metal layer and the first connection bonding pad are arranged at an interval. The first insulating layer comprises a first to-be-wired area, the second insulating layer is arranged on the first insulating layer and comprises a second to-be-wired area, the second insulating layer covers the first metal layer and the first connecting bonding pad, the second metal layer and the second connecting bonding pad are arranged in the second to-be-wired area and are arranged at intervals, and the third insulating layer is arranged on the second insulating layer. The third insulating layer covers the second metal layer and the second connecting bonding pad, and the third insulating layer is provided with openings in areas corresponding to the first connecting bonding pad and the second connecting bonding pad. Based on the embodiment of the invention, thousand-magnitude brain electrode signal connection can be realized under the processing capability of the flexible electronic circuit.

Description

technical field [0001] The invention relates to the technical field of microelectronic packaging and interconnection, in particular to a structure, a preparation method and a brain electrode device of a flexible connecting cable. Background technique [0002] With the development of brain science and technology, the collection of high-quality and high-density EEG signals has become an indispensable condition for precise interpretation of brain science. In recent years, the number of brain electrode channels has grown from single digits to thousands. Since mice, rats or monkeys are generally selected as experimental objects in the early development of brain electrodes, and the back-end circuits need to be miniaturized, so for the front-end signal acquisition The connection requirements between the device and the back-end circuit are relatively strict, and it is necessary to achieve a small volume while achieving high-channel connection, that is, it is necessary to take into a...
