In order to better understand the circuit information query method and the user terminal disclosed in the embodiments of the present invention, a network architecture suitable for the embodiments of the present invention is described below. Referring to fig. 1, fig. 1 is a schematic structural diagram of a network architecture according to an embodiment of the present invention. As shown in fig. 1, the network architecture diagram may include an IC information server and a UE, where the IC information server may include a server, a service host, a service system, a service platform, and the like, and the UE may be any device with communication and storage functions, such as: the mobile terminal includes intelligent devices with network functions, such as a tablet computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a Personal Digital Assistant (PDA), a notebook computer, and a wearable device. Wherein, the IC information server can be connected with the UE through the internet.
Based on the network architecture shown in fig. 1, the embodiment of the invention discloses a structural schematic diagram of the network architecture. Referring to fig. 2, fig. 2 is a schematic flow chart of a circuit information query method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:
s201, scanning an identification code on a target integrated circuit IC by user equipment UE through a camera of the UE.
S202, the UE acquires the information of the target IC corresponding to the identification code and stored in an IC information server in communication connection with the UE.
As an optional implementation manner, a specific implementation manner of the UE acquiring the information of the target IC corresponding to the identification code stored in an IC information server communicatively connected to the UE may be:
and the UE queries an IC information server in communication connection with an IC query application installed in the UE by taking the identification code as the unique index identifier of the target IC, and acquires the information of the target IC corresponding to the identification code.

As an alternative embodiment, the identification code comprises a two-dimensional barcode or a one-dimensional barcode.
As an optional implementation manner, when the identification code includes a two-dimensional barcode, a direction to which a corner without positioning in the two-dimensional barcode on the target IC belongs matches a chip direction of the target IC.
The two-dimensional code may include a stacked/row two-dimensional code, a matrix two-dimensional code, or the like. The coding principle of the stacked/row-type two-dimensional code is established on the basis of a one-dimensional bar code and is stacked into two or more rows according to needs. For example, Code 16K, Code 49, PDF417, etc. are representative stacked/row two-dimensional codes. The matrix type two-dimensional code is coded in a rectangular space through different distribution of black and white pixels in a matrix. At the corresponding element positions of the matrix, the binary '1' is represented by the appearance of black points (square points, round points), squares or other figures, the binary '0' is represented by the absence of the black points, squares or other figures, and the arrangement combination of the points, the squares or other figures determines the meaning represented by the matrix type two-dimensional code.

As an optional implementation manner, when the identification code includes a two-dimensional barcode, a direction to which a corner without positioning in the two-dimensional barcode on the target IC belongs matches a chip direction of the target IC.
The two-dimensional code may include a stacked/row two-dimensional code, a matrix two-dimensional code, or the like. The coding principle of the stacked/row-type two-dimensional code is established on the basis of a one-dimensional bar code and is stacked into two or more rows according to needs. For example, Code 16K, Code 49, PDF417, etc. are representative stacked/row two-dimensional codes. The matrix type two-dimensional code is coded in a rectangular space through different distribution of black and white pixels in a matrix. At the corresponding element positions of the matrix, the binary '1' is represented by the appearance of black points (square points, round points), squares or other figures, the binary '0' is represented by the absence of the black points, squares or other figures, and the arrangement combination of the points, the squares or other figures determines the meaning represented by the matrix type two-dimensional code. For example, Code One, Maxi Code, QR Code, Data Matrix, and the like are all representative Matrix two-dimensional codes.
As can be appreciated, existing circuit board photoresist layers, insulating layers, and copper foil layers. The insulating layer has opposing first and second surfaces. The first surface is parallel to the second surface. The first surface and the second surface are respectively provided with a copper foil layer, namely the circuit board is a double-layer circuit board. The photoresist layer is on the surface of the copper foil layer on the first surface of the insulating layer. The circuit board may be a single-layer circuit board having only one copper foil layer, or a multilayer circuit board having two or more copper foil layers. The circuit board has a molding region and an edge region surrounding the molding region. That is, the edge region is located outside the molding region. The molding area is an area for finally forming a finished circuit board product, and the edge area is an area which needs to be cut and removed when the finished circuit board product is formed.
Taking the two-dimensional code as an example of a matrix two-dimensional code, the matrix two-dimensional code is formed by arranging black and white pixel squares in a matrix. The two-dimensional code generating device can randomly generate different matrix type two-dimensional codes. The two-dimension code is acquired and displayed by a liquid crystal display device connected with a two-dimension code generating device, then the marking area of the circuit board where the mark is required to be formed is aligned with the liquid crystal display device, an exposure light source is started to expose the photoresist layer 230 of the circuit board, so that the exposure mark is formed in the area of the photoresist layer of the circuit board where the mark is required to be formed, and the exposure light source is preferably an ultraviolet light source. And then developing the position of the exposure mark of the photoresist layer by using the developing solution, thereby removing the unnecessary part of the photoresist in the exposure mark, so that a developed pattern corresponding to the exposure pattern is formed in the photoresist layer. The photoresist area which is removed by development in the development pattern corresponds to the white pixel area in the two-dimensional code exposure pattern. And finally, etching by using an etching device to form the two-dimensional code mark.
