Title:
CIRCUIT BOARD AND OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2024/051224
Kind Code:
A1
Abstract:
The present disclosure provides a circuit board and an optical module. The circuit board comprises a top layer, a bottom layer, and a plurality of middle layers stacked between the top layer and the bottom layer; the top layer is provided with a data processing chip and first and second rows of golden fingers, and the first row of golden fingers are closer to the edge of the circuit board than the second row of golden fingers; first and second rows of hollowed-out areas corresponding to the first and second rows of golden fingers are provided on the middle layers, first and second high-speed signal line groups are provided on one middle layer, one side of the first high-speed signal line group is connected to the second row of golden fingers, one side of the second high-speed signal line group passes through the first row of hollowed-out areas to be connected to the first row of golden fingers, and the other side of the first high-speed signal line group and the other side of the second high-speed signal line group are connected to the data processing chip by means of a first through hole between the middle layers and the top layer. According to the present disclosure, a plurality of high-speed signal lines are provided on the middle layers of the circuit board, no high-speed signal line is provided on the top layer, and the high-speed signal lines pass through the hollowed-out areas to be connected to the golden fingers, so that the layout space of the top layer is saved, and the high-speed performance of the optical module is improved.
