AI Technical Summary

Technical Problem

Existing modular PCB boards are prone to compression and wrinkles during high-temperature and high-pressure overlapping, and are difficult to operate, making it difficult to ensure the tight fit and electrical performance of multi-layer PCB boards.

Method used

A modular PCB board structure including a bottom bracket, a plurality of PCB substrates, a pressing plate, a rotating rod and a limiting member is designed. By continuously rotating the rotating rod, the extruder presses the movable rod, so that the multiple rotating rods move downwards one by one and rotate the bonding plate, so that the multiple PCB substrates from bottom to top are closely fitted one by one.

Benefits of technology

It achieves a tight fit between multiple PCB substrates, avoids compression and wrinkle phenomenon, is simple to operate and low cost, is suitable for the needs of multi-layer circuit boards with fast installation and compact structure and excellent electrical performance, and supports the installation, disassembly, replacement and reuse of PCB substrates.

Abstract

The invention discloses a modular PCB convenient for rapid expansion, which comprises a bottom supporting plate, a plurality of PCB substrates, a pressing plate, a rotating rod, a driving rod and a rotating rod, a movable rod is arranged between the rotating rod and the rotating rod through a limiting piece, extrusion pieces for extruding the movable rod are arranged at the top ends of the driving rod and the rotating rod, and the middle part of the movable rod is provided with the pressing plate through a control piece. The pressing plate is matched with the rotating rod in a pressing manner; by continuously rotating the rotating rod, the plurality of PCB substrates from bottom to top move downwards in sequence, so that layer-by-layer tight attachment is achieved, not all the PCB substrates are pressed at the same time, pressing is performed in sequence and gradually extruded from bottom to top, the plurality of PCB substrates are tightly attached in the mode, and the mode is simple and convenient to operate, low in cost and high in efficiency. The multi-layer circuit board is convenient to mount quickly, compact in structure and excellent in electrical performance, one PCB substrate can be mounted, dismounted and replaced, reutilization is facilitated, and sustainable development is realized.
