In the related art, test files needed by the flying probe device in the test process are usually generated based on schematic diagrams such as circuit diagrams of the to-be-tested elements, however, the structures of some to-be-tested elements are complex; for example, a three-dimensional connector is a ceramic multilayer three-dimensional circuit substrate, and pad pins on the three-dimensional connector are distributed on planes with different heights, and the pad pins are used for circuit connection between electronic devices. When the three-dimensional connector is used as a component to be tested, the pad pin is the point to be tested; based on the circuit connection function of the three-dimensional connector, the connection relation between the pad pins is determined, and the connection relation between the pad pins can be tested through the flying probe equipment. However, due to the complicated structure of the stereo connector, the test file thereof is difficult to be acquired through the schematic diagram thereof. Based on this, the embodiment of the invention provides a method and a device for generating a test file of a resistor network and electronic equipment, which can be applied to a circuit board or an electronic element with a complex structure.
To facilitate understanding of the present embodiment, first, a method for generating a test file of a resistor network disclosed in the present embodiment is described in detail.
The embodiment of the invention provides a test file generation method of a resistance network, which is applied to electronic equipment, wherein the electronic equipment is connected with flying probe equipment and image acquisition equipment, and the method is shown in a flow chart shown in figure 1; the electronic device may comprise the following steps for a computer:
step S100, obtaining a component to be tested; the element to be tested comprises a set number of points to be tested.
The element to be tested is usually an electronic element or a circuit board with a complex structure and comprises a plurality of points to be tested; the points to be measured may not be in the same plane. The connection relation between the points to be measured of the element to be measured is determined, whether the connection relation between the points to be measured is the same as the preset connection relation or not can be measured through the flying probe device, and therefore whether the resistance network of the element to be measured is normal or not is judged.
And S102, acquiring the geometric coordinate information of the point to be measured through the flying probe equipment and the image acquisition equipment.
Specifically, the image acquisition equipment can be fixed on a measuring probe of the flying probe equipment, and the measuring probe and the image acquisition equipment are driven to move by a motor of the flying probe equipment; aligning the point to be measured through an image acquired by image acquisition equipment, determining the coordinate of the point to be measured in a coordinate system where a measuring pin of the flying pin equipment is located through the step pitch of the motor movement, and taking the coordinate as coordinate information; the coordinates may include parameters for the set X and Y directions. The point to be measured may be a regular geometric figure, such as a rectangle, a circle, etc., and may have a certain area; the center of the image collected by the image collecting device can be aligned to the geometric center of the point to be measured, and the obtained coordinate information is the coordinate of the geometric center of the point to be measured.
At this time, the geometric figure of the point to be measured can also be recorded, for example, when the point to be measured is a circle, the radius of the circle is recorded, or an image of the point to be measured in the image acquisition device is directly drawn as the geometric shape information of the point to be measured.
And step S104, generating a test file of the element to be tested according to the geometric coordinate information and the pre-acquired network relationship of the test points.
The network relation refers to whether each test point belongs to the same network or not, the test points belonging to the same network are mutually conducted, and the test points belonging to different networks are mutually insulated. The purpose of the test is to test whether there is a break between test points in the same network or whether there is a short between test points in different networks.
The test file adopted by the flying probe device in the test usually has a specific format, and the file can be an IPC-D-356A file and the like, wherein the IPC (Industrial Personal computer) is an industrial Personal computer. After each test point of the element to be tested is numbered, the coordinate information, the geometric shape information and the connection relation with other test points are stored as the test file of the element to be tested according to the set format of the test file.
The embodiment of the invention provides a test file generation method of a resistance network, which comprises the steps of obtaining a to-be-tested element, and then obtaining the geometric coordinate information of a to-be-tested point through a flying probe device and an image acquisition device; and generating a test file of the element to be tested according to the coordinate information, the geometric shape information and the pre-acquired network relationship of the test points. The method can obtain the test file of the element to be tested with a complex structure or without a schematic diagram, thereby realizing the test of the resistance network of the element to be tested through the flying probe equipment.
The embodiment of the invention also provides another test file generation method of the resistance network, which is realized on the basis of the method in the embodiment; the embodiment mainly describes the process of acquiring the geometric coordinate information of a point to be measured through the flying probe device and the image acquisition device and generating a test file of the element to be measured when the geometric coordinate information comprises coordinate information and geometric shape information; as shown in fig. 2, the method comprises the steps of:
step S200, obtaining a component to be tested; the element to be tested comprises a set number of points to be tested.
And S202, driving the measuring needle to move through the motor, so that the center of the image acquired by the camera is superposed with the geometric center of the point to be measured.
Specifically, the image capturing Device may be a Charge-coupled Device (CCD) -based camera; the camera is used for collecting images; the flying probe equipment comprises a probe and a motor; the camera is fixed on the measuring needle; the motor can drive the measuring needle and the image equipment to move together.
When the motor drives the measuring needle to move, the motor in the X direction generally controls the measuring needle to move in the X direction, and the motor in the Y direction controls the measuring needle to move in the Y direction; and outputting a pulse at a controller of the motor, and driving the measuring needle to move by the set step pitch by the motor. The center of an image acquired by a motor camera is usually shown on the image through a cross icon, and when the point to be measured is circular and the cross icon coincides with the circle center of the point to be measured, the center of the image acquired by the camera is determined to coincide with the geometric center of the point to be measured.
Step S204, determining coordinate information of the point to be measured through the X-direction moving step distance and the Y-direction moving step distance between the measuring needle and a preset reference point; specifically, the reference point may be a position where the stylus is located at the time of initialization, the reference point is set as a zero point of a coordinate system where the stylus is located, a moving distance of the stylus is known every time the stylus moves by one step, and when a moving step or an actual moving distance of the stylus is taken as a coordinate unit, an X-direction moving step and a Y-direction moving step which are passed in a process where the stylus moves from the reference point to a current point are cumulatively acquired, and coordinates of the point to be measured in the coordinate system where the stylus is located may be determined.
And step S206, recording the geometric image of the point to be measured on the image acquired by the camera.
Specifically, an image acquired by a camera and the geometric shape of the point to be measured can be read, a corresponding graph (circle, square or rectangle) is selected, the radius, side length, width and height of the graph are adjusted through a software slider, the shape is drawn on a CCD image in real time during adjustment, the adjusted shape is completely overlapped with the point to be measured, and therefore the geometric image of the point to be measured on the image is recorded.
And step S208, obtaining the geometric shape information of the point to be measured through the geometric image and the pixel pulse ratio value obtained in advance.
Specifically, the above pixel pulse ratio value can be determined by:
(1) driving a measuring needle and a camera to move by a set step pitch in the X direction and the Y direction through a motor, and recording a pixel value of the movement of the center of an image acquired by the camera; specifically, the X and Y motors moving a certain probe (such as probe No. 1) move by a fixed step distance, and pixel values of the corresponding X and Y directions of the center of the CCD image after the step distance is completed are recorded.
(2) Calculating a pixel pulse ratio according to the pixel value and the step pitch; specifically, in the process, the number of steps is converted into the number of pulses by referring to the proportional relation between the steps and the pulses, and the ratio of the pixel value of the image center movement to the number of pulses is calculated, so that the pixel pulse ratio is obtained.
The parameters of the geometric image, such as radius or side length, can be expressed by pixels, and in order to be unified with the unit of the coordinate information of the point to be measured, the unit of the parameters of the geometric image can be converted into a unit unified with the coordinate information of the point to be measured by pixel pulse ratio, such as the unit of step distance or the unit of millimeter.
Step S210, storing the coordinate information, the geometric shape information, and the connection relationship of each test point of the test points as a test file of the device to be tested according to a preset test file format.
Specifically, the network relationship includes a connection relationship between every two test points in the to-be-tested element; the connection relation comprises conduction or insulation; the preset format can be the format of an IPC-D-356A file.
According to the test file generation method of the resistance network, after an element to be tested is obtained, a motor drives a measuring pin to move, so that the center of an image collected by a camera is coincided with the geometric center of the point to be tested, and the coordinate information of the point to be tested is determined through the X-direction moving step distance and the Y-direction moving step distance between the measuring pin and a preset reference point; after recording a geometric image of the point to be measured on an image acquired by a camera, acquiring geometric shape information of the point to be measured through the geometric image and a pixel pulse ratio acquired in advance; and generating a test file of the element to be tested according to the coordinate information, the geometric shape information and the pre-acquired network relationship of the test points. The method can obtain the test file of the element to be tested with a complex structure or without a schematic diagram, thereby realizing the test of the resistance network of the element to be tested through the flying probe equipment.
The embodiment of the invention also provides an editing method of the on-line test file of the three-dimensional connector, which is realized on the basis of the method in the embodiment.
Due to the particularity of the three-dimensional connector, when the flying probe device is used for testing the on-off relationship of the resistance network, a test file capable of extracting the coordinate information of the test point cannot be provided generally, so that a method capable of directly editing the coordinate information of each test point on the three-dimensional connector is needed. In the method, the test file of the three-dimensional connector is generated by observing the CCD image and matching with the positioning of the motor, as shown in FIG. 3, the method specifically comprises the following steps:
1. and fixing the CCD camera on a first measuring pin for calibration.
2. And moving the X-direction motor and the Y-direction motor of the first measuring pin by a fixed step distance, and simultaneously recording pixel values of the corresponding X-direction and Y-direction movement of the center of the CCD image after the step distance is finished. The pixel pulse ratio of the CCD camera in the whole motion coordinate system (i.e. the pixel pulse ratio of the calibration CCD relative to the direction X, Y) is calculated by the group of data.
3. And moving the center of the CCD image to coincide with the geometric center of the point to be measured.
4. Selecting a graph (circle, square or rectangle) according to the geometric shape of the point to be measured, adjusting the radius, side length, width and height of the graph (namely editing the information of the test point under an image interface) through a software slider, drawing the graph on a CCD image in real time during adjustment, recording the real-time position of the X, Y motor and the geometric shape information (recording coordinates) of the test point when the image is adjusted to be completely coincided with the point to be measured (a cross cursor at the center of the CCD image is aligned with the geometric center of the test point), and writing the information into a file after numbering the graph (namely writing the geometric figure information of the position coordinates of the test point into the file).
5. And repeating the steps of 3-4 to write the information of each point to be measured on the three-dimensional connector into a file.
6. And reading the test point information file, and compiling a test file for testing the device by the flying probe equipment according to the network relation between the test points on the three-dimensional connector.
In the specific implementation process, the method is added into the flying probe industrial control software as a functional module; the method can obtain the test file of the three-dimensional connector, so that the resistance network of the element to be tested can be tested through the flying probe equipment.
