Problems solved by technology

With the fine and short design of PCB, the design of this positioning hole can only be realized at the expense of layout utilization, which increases the production cost, and if different products are designed, the position of the positioning hole is inconsistent, resulting in different steel plates for lamination Fixtures, so the production efficiency is low and the cost is high

Abstract

A local hybrid circuit board structure comprises a printed circuit board mother board, the printed circuit board mother board comprises a plurality of circuit substrates, a groove used for containinga printed circuit board daughter board is formed in the printed circuit board mother board, and the width of the groove is gradually reduced in the direction from an opening to the bottom face of thegroove. In addition, the invention also provides a manufacturing method of the local hybrid circuit board structure. Meanwhile, the bottom surface of the groove is matched with the bottom surface of the daughter board in size, so the embedding precision is ensured.

Description

technical field [0001] The invention relates to a circuit board structure and a manufacturing method thereof, in particular to a local mixed voltage circuit board structure and a manufacturing method thereof. Background technique [0002] In the traditional PCB design process, if high-frequency signals are required, it is usually necessary to use high-frequency materials. For example, high-frequency materials are used in all layers of the entire circuit board, high-frequency materials are used in partial layers, or high-frequency materials are used in local areas. Products that use high-frequency materials are often expensive, and the industry usually adopts the production method of embedding high-frequency materials in local areas. Embedding high-frequency materials in local areas usually includes direct embedding and pin positioning. [0003] When using the direct embedding method, the size of the daughter board must be smaller than the opening size of the mother board. ...
