Abstract

The invention provides a circuit board, which comprises: a circuit stack-up structure comprising a first main body part and a through groove arranged on the first main body part in a penetrating manner; a heat dissipation unit arranged in the through groove, wherein the heat dissipation unit comprises a second main body part and a pin, and the second main body part is clamped with the first main body part through the pin; and a filling unit arranged between the first main body part and the second main body part. The invention further provides a manufacturing method of the circuit board.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board and a manufacturing method thereof. Background technique [0002] Optical fiber connector is an important component to realize the connection between electronic products and optical fiber network. The optical fiber connector includes a circuit board, and the circuit board is used as the carrier of electronic devices to connect electronic components to each other. In the optical fiber connector, the conversion between electrical signals and optical signals is realized through the driver chip. However, a large amount of heat energy will be generated during the conversion process, and the heat will cause the internal temperature of the components to rise rapidly. Requirements, it is necessary to use an additional heat dissipation unit (such as a metal block) to assist heat dissipation. [0003] In order to solve this problem, the industry usually forms an inn...
