Description
Technical Field
The invention belongs to the technical field of multilayer PCBs, and particularly relates to a multilayer PCB riveting system.
Background
The printed circuit board is a core component of modern electronic equipment and is widely applied to the fields of computers, communication equipment, consumer electronics, automobile electronics and the like. With the continuous development of electronic products and the increase of functional requirements, the number of layers and complexity of PCBs are also increasing. The application of multi-layer PCBs is gradually increasing to meet the demands of high-density wiring, signal transmission stability, compactness, and the like.
Conventional multi-layer PCB connection technologies mainly employ soldering technologies, such as Surface Mount Technology (SMT) or card soldering technologies. However, these conventional connection techniques have some problems in facing high-density wiring and complex circuit structures. First, the high temperature generated during soldering is liable to damage the PCB materials and devices. Second, the solder joints may come loose or crack due to temperature changes, vibration, or mechanical stress, resulting in unstable electrical connections, thereby affecting the performance and lifetime of the device.
In order to solve the problems of the conventional welding technology, the riveting technology gradually attracts a great deal of attention. The staking technique replaces the traditional soldering method by forming a strong mechanical connection at the junction of the multi-layer PCB. The riveting technology is applied to aerospace, military equipment and other high-reliability electronic equipment, has the advantages of high temperature resistance, vibration resistance, high reliability and the like, and enables the multilayer PCB to perform better in a harsh working environment.
However, in existing frames, maintenance of the weld head is often a challenge. The molten rivet head frequently works under high temperature and high pressure and is easy to wear, corrode and deform, so that the service life of the molten rivet head is reduced, and the frequency and cost of equipment maintenance are increased. In addition, once the rivet head fails, the entire rivet head assembly may need to be replaced, further increasing production downtime and maintenance costs.
