Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a novel flexible chip interface connector. Background Technology

[0002] Memory chips are used to store data. In harsh environments, they are often placed in a sealed enclosure and connected to an external circuit board via a circuit board. Harsh environments can easily damage the gold fingers of the circuit board. When data needs to be read, the chip must be removed and re-soldered using the same circuit board, which is time-consuming, labor-intensive, and significantly increases costs.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel flexible chip interface connector, which facilitates data reading when the circuit board is damaged and is convenient for application.

[0005] The technical solution of this utility model is as follows: A novel flexible chip interface connector is provided, comprising: a flexible circuit board, a chip, a main gold finger, a spare gold finger, and a chip reinforcement plate; the flexible circuit board includes: a chip soldering area and an interface strip connected to the chip soldering area, the chip soldering area and the interface strip being integrally formed; the chip is soldered onto the chip soldering area, the chip reinforcement plate is adhered to the chip soldering area, and the chip and the chip reinforcement plate are respectively disposed on two sides of the chip soldering area; the main gold finger is disposed at the end of the interface strip away from the chip soldering area, and the spare gold finger is disposed at the end of the interface strip closer to the chip soldering area. Furthermore, the chip is directly soldered onto the flexible circuit board, thus eliminating the need for a dedicated process of joining a rigid board and a flexible circuit board, effectively saving production costs and improving production efficiency. In normal application, the main gold finger serves as the data input / output port. When the main gold finger burns out at high temperature, it is cut along the edge of the spare gold finger with scissors to expose the spare gold finger as a backup interface. In this solution, both the main gold finger and the spare gold finger can be used in tooling equipment for reading and writing data; when the main gold finger is damaged, the spare gold finger can be used.

[0006] Furthermore, the novel flexible interface connector for the chip also includes: a main reinforcing plate adhered to the back of the main gold finger and a spare reinforcing plate adhered to the back of the spare gold finger. The main reinforcing plate is used to strengthen the main gold finger and facilitate insertion; similarly, the spare reinforcing plate is used to strengthen the spare gold finger and facilitate insertion.

[0007] Furthermore, the main reinforcing plate and the spare reinforcing plate are made of FR4 plate or PI material, and the thickness of the main reinforcing plate and the spare reinforcing plate is 0.1mm-0.4mm.

[0008] Furthermore, the novel flexible chip interface connector further includes a shielding layer attached to the interface strip, the shielding layer being disposed on the back side of the surfaces containing the main gold fingers and the spare gold fingers. The shielding layer does not extend to the main gold fingers or the spare gold fingers. The shielding layer is used to shield against interference from external signals, ensuring stable and reliable signal transmission.

[0009] Furthermore, the chip reinforcement plate is made of FR4 board or PI material reinforcement plate, and the thickness of the chip reinforcement plate is 0.2mm-0.6mm.

[0010] Using the above solution, this utility model provides a novel flexible chip interface connector. By directly soldering the chip onto the flexible circuit board, the main gold finger serves as the data input / output port during normal application. When the main gold finger burns out at high temperature, it can be cut along the edge of the spare gold finger with scissors to expose the spare gold finger as a backup interface. In this solution, both the main gold finger and the spare gold finger can be used in tooling equipment for reading and writing data. When the main gold finger is damaged, the spare gold finger can be used. Attached Figure Description
