Description

Novel chip flexible interface connector Technical Field The utility model relates to the technical field of connectors, in particular to a novel chip flexible interface connector. Background The memory chip is a chip for storing data, and in some application scenarios in severe environments, the memory chip is placed in a sealed box, and the memory chip and an external circuit board are connected through a circuit board. The golden finger of circuit board is easily led to the fact the damage to the application scenario in adverse circumstances, when the data of chip need be read, can only pull down the chip to adopt the circuit board of same type to weld again and read, waste time and energy, very big increase cost. Accordingly, the prior art has drawbacks and needs improvement. Disclosure of utility model The utility model aims to solve the technical problem of providing the novel chip flexible interface connector which is convenient for reading data when the circuit board is damaged and convenient for application. The technical scheme is that the novel chip flexible interface connector comprises a flexible board, a chip, a main golden finger, a standby golden finger and a chip reinforcing plate, wherein the flexible board comprises a chip welding area and an interface strip connected with the chip welding area, the chip welding area and the interface strip are integrally formed, the chip is welded on the chip welding area, the chip reinforcing plate is adhered to the chip welding area, the chip and the chip reinforcing plate are respectively arranged on two side surfaces of the chip welding area, the main golden finger is arranged at one end of the interface strip far away from the chip welding area, and the standby golden finger is arranged at one end of the interface strip close to the chip welding area. Further, the chip is directly welded on the soft board, so that a special procedure of jointing the hard board and the flexible circuit board is not needed, the production cost can be effectively saved, and the production efficiency can be effectively improved. When the device is normally applied, the main golden finger is used as an input/output port of data, when the main golden finger is burnt out at high temperature, scissors are used for shearing along the edge of the spare golden finger, and the spare golden finger is exposed to be used as a spare interface. In the scheme, the main golden finger and the standby golden finger can be used for the tooling equipment to read and write data, and the standby golden finger can be used when the main golden finger is damaged. Further, the novel flexible interface connector of the chip further comprises a main reinforcing plate adhered to the back of the main golden finger and a standby reinforcing plate adhered to the back of the standby golden finger. The main reinforcing plate is used for reinforcing the strength of the main golden finger and is convenient to plug, and the standby reinforcing plate is used for reinforcing the strength of the standby golden finger and is convenient to plug. Further, the main reinforcing plate and the standby reinforcing plate are made of FR4 plates or PI materials, and the thicknesses of the main reinforcing plate and the standby reinforcing plate are 0.1mm-0.4mm. Further, the novel chip flexible interface connector further comprises a shielding layer attached to the interface strip, wherein the shielding layer is arranged on the back surface of the surface where the main golden finger and the standby golden finger are located. The shielding layer does not extend to the main golden finger and the standby golden finger. The shielding layer is used for shielding interference of external signals and guaranteeing stable and reliable signal transmission. Further, the chip reinforcing plate is made of FR4 plates or PI materials, and the thickness of the chip reinforcing plate is 0.2mm-0.6mm. By adopting the scheme, the novel chip flexible interface connector is provided by the utility model, the chip is directly welded on the flexible board, the main golden finger is used as the data input/output port in normal application, and when the main golden finger is burnt out at high temperature, the scissors are used for shearing along the edge of the spare golden finger, so that the spare golden finger is exposed to serve as a spare interface.
