Abstract

The invention relates to a double-sided circuit board structure which comprises a circuit board, a first chip group and a second chip group. The circuit board comprises a partition layer, a first multi-layer structure and a second multi-layer structure, the partition layer comprises a first surface and a second surface opposite to the first surface, the first multi-layer structure forms on the first surface, and the second multi-layer structure forms on the second surface. Each multi-layer structure comprises a first line layer, an intermediate layer and a second line layer, wherein the first line layer is formed on the first surface or the second surface, and the second line layer is formed on the intermediate layer which is formed on the first line layer and comprises a conductive line portion and a grounding portion. The first chip group is arranged on the grounding portion of the first multi-layer structure and electrically connected with the conductive line portion of the first multi-layer structure. The second chip group is arranged on the grounding portion of the second multi-layer structure and electrically connected with the conductive line portion of the second multi-layer structure.

Description

technical field [0001] The invention relates to a double-sided circuit board structure. Background technique [0002] At present, the development of computer technology requires the calculation / processing speed of electronic devices, the data transmission speed between electronic devices to be faster and faster, and / or the electronic devices to integrate more and more functions. Faster computing / processing speed, transmission speed and more functions will inevitably require electronic devices to integrate more electronic components. However, integrating more electronic components will increase the width of the circuit board carrying these electronic components, which is not in line with the current trend of miniaturization of electronic devices. Contents of the invention [0003] In view of this, it is necessary to provide a double-sided circuit board structure that can improve the integration of electronic components without increasing the width of the circuit board, so ...
