Description
Technical Field
[0001] The utility model relates to the technical field of circuit board pressing, in particular to a multi-layer circuit board pressing device. Background Art
[0002] A multilayer circuit board has at least three conductive layers, two of which are on the outer surface, and the remaining layer is synthesized in the insulating board. The electrical connection between them is usually achieved through plated through holes on the cross section of the circuit board. Its advantages are: high assembly density, small size, and light weight. Due to the high assembly density, the number of connections between components (including components) is reduced, thereby improving reliability; the number of wiring layers can be increased, thereby increasing design flexibility; a circuit with a certain impedance can be formed; a high-speed transmission circuit can be formed; a circuit and magnetic circuit shielding layer can be set, and a metal core heat dissipation layer can be set to meet the needs of special functions such as shielding and heat dissipation; the installation is simple and the reliability is high. However, the currently used pressing device lacks a fixed structure on both sides, which leads to the problem of circuit board misalignment during the pressing process. At the same time, pressing the pressing plate too deep will also cause damage to the circuit board. For this reason, we propose a multilayer circuit board pressing device. Utility Model Content
