Embodiment 1
[0054] In view of the above problems, the embodiment of the present application provides a method for determining the back-drilling depth of a printed circuit board, which can simply and quickly obtain the drilling depth data of back-drilling holes in different regions.
[0055] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0056] figure 1 It is a schematic flowchart of a method for determining the back-drilling depth of a printed circuit board shown in the embodiment of the present application.
[0057] see figure 1 , the method for determining the back drilling depth of the printed circuit board, comprising:
[0058] 101. Obtain the structural information of the printed circuit board PCB;
[0059] The structural information includes: the actual size of the PCB, the position coordinates of the back-drilled holes, and the initial drilling depth of the back-drilled holes;
...
Embodiment 2
[0093] In practical applications, this embodiment of the present application designs step 102 in the first embodiment above. figure 2 It is a schematic flow chart of the method for obtaining area information of back-drilled holes. For details, see figure 2 , the obtaining area information of the back-drilled hole based on the structural information includes:
[0094] 201. Establish a coordinate system according to the PCB;
[0095] Exemplary:
[0096] A coordinate system is established with one corner of the PCB as the origin, one long side as the x-axis, and the short side connected to the origin as the y-axis.
[0097] It should be noted that the present invention does not have strict limitations on the establishment of the coordinate system. For example, in practical applications, one corner of the PCB can be used as the origin, one short side is the x-axis, and the long side connected to the origin Establish a coordinate system for the y-axis.
[0098] It can be unde...
Embodiment 3
[0111] In practical applications, the embodiment of the present application designs the calculation method of the drilling depth compensation value in step 103 in the first embodiment above. image 3 For the flow diagram of the calculation method of drilling depth compensation value, please refer to image 3 , the calculation method of the drilling depth compensation value, comprising:
[0112] 301. Obtain the thickness difference between the first area and the second area;
[0113] In the embodiment of the present application, the thickness difference between the first region and the second region can be obtained by measuring the thickness of the first region and the thickness of the second region respectively by a PCB thickness measuring instrument.
[0114] It should be noted that, the embodiment of the present application does not strictly limit the acquisition process of the thickness difference, and the computer can acquire it based on the information imported by the us...
