Description

PCB board with crooked function Technical Field The utility model relates to the technical field of circuit boards, in particular to a PCB with a bending function. Background The PCB with the bending function has great significance in the field of modern electronic equipment manufacturing, and is widely applied to various fields such as wearable equipment, intelligent home, aerospace and the like. The bending device can bend according to the internal space and functional requirements of the equipment, effectively improves the space utilization rate and optimizes the circuit layout. In the field of aerospace, the space structure of the interior complex of adaptable aircraft, meet the special circuit design requirement, at present, the PCB board with bending function generally needs the following technology in practical application: 1. The substrate material with high flexibility and bendability ensures that the PCB can be bent safely within a certain range without damaging the internal circuit; 2. Advanced circuit wiring and packaging technology, so that the circuit maintains good electrical connection and performance stability in the bending process; 3. A reliable protective coating technology for protecting the bent PCB from being corroded by the external environment; 4. The component shape selection and layout method matched with the bending characteristics ensures that the component can still work normally when the PCB is bent. Currently, various techniques and modes are used to implement the bending function of the PCB board. Some manufacturers produce flexible PCB boards by selecting special flexible substrate materials, such as Polyimide (PI) films, in combination with flexible circuit printing techniques.
