In this embodiment, a method for replacing a component operating in an electronic device is provided, and fig. 2 is a flowchart of a method for replacing a component according to an embodiment of the present application, where as shown in fig. 2, the flowchart includes the following steps:
step S202, selecting a target program from a plurality of preset programs according to the device type of the component to be detected, and detecting the equipment component in a target area by using the target program to obtain a detection result of the equipment component;
step S204, determining at least one target component with the component type being the component type of the component to be detected from the equipment assembly according to the detection result, and acquiring an actual tolerance corresponding to the at least one target component;
and step S206, determining whether the at least one target component needs to be replaced according to the preset tolerance and the actual tolerance of the equipment assembly.
Optionally, the preset tolerance is a maximum tolerance value allowed for packaging different components when the device assembly is packaged. When a plurality of different target components exist in the equipment assembly, the corresponding preset tolerance is a maximum tolerance value list of the plurality of different target components which are correspondingly allowed to be packaged.
It should be noted that the preset tolerance is not constant, and can be flexibly changed based on actual use requirements, and the application is not limited to this.
Through the above-mentioned step, utilize the target form to carry out the tolerance detection to the equipment subassembly in the detection target region, it uses the components and parts of big tolerance part problem to determine to exist among the equipment subassembly, and on the basis and directly replace into the components and parts of corresponding little tolerance with these components and parts, and can replace into suitable tolerance device with other components and parts that exist big tolerance part problem among the equipment subassembly one by one and put, consequently, can solve that the components and parts replacement scheme is complicated, the low scheduling problem of replacement efficiency, reach the detection efficiency who promotes circuit board overall arrangement, improve the effect that detects the degree of accuracy, and further improved the design quality of circuit board overall arrangement.
The executing subject of the above steps may also be a server, a terminal, etc., but is not limited thereto.
It should be noted that the target program is an automatically operating detection program, for example, in the Layout design of PCB Layout, by writing a skip program for automatically checking the pitch specifications of different 0402 packaged devices, the skip program can import the material information (the specification of the material has tolerance information) of each 0402 in the component library, and then put the skip program into a skip menu to load a large tolerance device type, and then execute the skip program to highlight which packaged devices have the problem of using large tolerance parts, and indicate the part coordinates thereof and highlight them, and directly SWAP (replace) the packaged devices with small tolerances, so that the skip program can shorten the checking time of the packaged devices and remove the problem of missing of manual checking, increase the accuracy, and achieve the purpose of improving the efficiency and quality.
In one exemplary embodiment, determining whether at least one target component needs to be replaced based on the preset tolerance and the actual tolerance of the equipment assembly includes: determining that at least one target component needs to be replaced when the actual tolerance is larger than the preset tolerance; and under the condition that the actual tolerance is less than or equal to the preset tolerance, determining that at least one target component does not need to be replaced.
It should be noted that in the layout design of PCB, the 0402 component is most often under a Ball Grid Array (BGA) chip, but due to the unreasonable design of the component pads, there are many defects, and the 0402 tolerance has a large or small tolerance, the maximum tolerance reaches 0.2mm, and the minimum tolerance is 0.05mm. The tolerance is four times worse. The large tolerance 0402 resistor, the size and height of which are significantly larger than the small tolerance, is more prone to bumping and tin bridging problems when using octagonal small packages. And then, a tolerance value can be preset, and under the condition that the actual tolerance is larger than the preset tolerance, the target component is determined to be required to be replaced. And under the condition that the actual tolerance is less than or equal to the preset tolerance, determining that the target component does not need to be replaced.
In addition, when two target components exist, the actual tolerance of one target component is larger than the preset tolerance, and the actual tolerance of the other target component is smaller than the preset tolerance, at the moment, when the replaced components are determined, suitable components with the actual tolerances smaller than the preset tolerance can be ignored, and only the components with the actual tolerances larger than the preset tolerance are marked for replacement.
In an exemplary embodiment, before determining, according to the detection result, that the device type in the equipment assembly is at least one target device of the device type of the device to be detected, the method further includes: acquiring a preset interval specification corresponding to a component to be detected and material information corresponding to the component to be detected, wherein the preset interval specification is a tolerance range of the component to be detected, which is allowed to be packaged on an equipment assembly, and the material information is used for indicating an incoming material error corresponding to the component to be detected; determining a type list corresponding to the component to be detected based on the preset distance specification and the material information, wherein the type list comprises: tolerance values of other components; the types of other components are the same as the components to be detected.
In order to ensure the accuracy of the target program for performing automatic detection on the component to be detected, a preset spacing specification of the component to be detected during packaging in the equipment assembly and a corresponding incoming material error of the component to be detected before actual assembly are required, where the incoming material error is a component delivery error corresponding to a manufacturer providing the component, and a unique type list belonging to the component to be detected is generated, and a reference of a replacement object can be provided when the component to be detected is replaced through the type list, as shown in table 1 below:
table 1:
the large tolerance is a large tolerance device type, the Small tolerance is a Small tolerance device type, the part-number item is a part number corresponding to the component, and the Value item is a tolerance Value corresponding to the component.
In an exemplary embodiment, before determining whether the at least one target component needs to be replaced according to the preset tolerance and the actual tolerance of the equipment assembly, the method further includes: acquiring a labeling result of a first image, wherein the labeling result is used for indicating the position of a component larger than a preset tolerance in the first image, and the first image is used for displaying the distribution state of different components on an equipment assembly; outputting a first replacement data table corresponding to the equipment component based on the labeling result, wherein the first replacement data table comprises: the device type corresponding to the target component and the actual tolerance corresponding to the target component.
It can be understood that, in order to avoid missing replacement of a target component in the equipment assembly, after determining a device type of the target component to be replaced, the distribution state of the same device type on the equipment assembly is identified by acquiring an image corresponding to the equipment assembly, and then the component to be replaced can be marked in the image, and whether the positions of the components meet the DFM specification is measured one by using a display measurement show measure function in an Allegro application, and corresponding measurement data is output as a first replacement data table, so that replacement can be performed based on the position corresponding to the mark in the image during replacement, and after the replacement is completed, whether the replacement operation is successfully performed can be determined by checking actual tolerance information of the corresponding mark position.
In an exemplary embodiment, after outputting the first replacement data table corresponding to the device component based on the annotation result, the method further includes: sending the first replacement data table to the engineering object, and receiving a replacement rule which is confirmed by the engineering object based on the first replacement data table; and adjusting the first replacement data table by using the replacement rule to obtain a second replacement data table.
Briefly, after a first replacement data table of tolerance data corresponding to a component needing to be replaced is determined, in order to guarantee reliability of replacement, the first replacement data table is sent to an engineering object, the engineering object carries out layout evaluation on manufacturability design of the component in an equipment assembly, corresponding evaluation opinions are output, replacement rules are determined according to the evaluation opinions, namely the manufacturability design can be met after the component is changed into any size, the opinions provided by DFM are modified, and the first replacement data table is adjusted to a second replacement data table.
In an exemplary embodiment, adjusting the first replacement data table using the replacement rule to obtain the second replacement data table includes: determining a replacement mode corresponding to the replacement rule, wherein the replacement mode at least comprises the following steps: replacing the large tolerance component with the small tolerance component; and adjusting the part number corresponding to the target component in the first replacement data table from the first number corresponding to the large tolerance component to the second number corresponding to the small tolerance component of the same component type by using a replacement mode so as to obtain a second replacement data table.
In an exemplary embodiment, after the adjusting the first replacement data table by using the replacement rule to obtain the second replacement data table, the method further includes: loading a second replacement data table into a target program including a plurality of programs; and under the condition that the target program finishes loading of the second replacement data table and receives an execution instruction sent by the target object, replacing the target component in the equipment assembly by using the second replacement data table, wherein the execution instruction is used for starting a replacement process of the target component.
In one exemplary embodiment, performing a replacement operation on a target component in a device assembly using a target data table to be executed includes: removing all target components in the equipment assembly; selecting a corresponding replacement component from the component storage space based on a target data table to be executed to set in the equipment assembly, and determining the actual tolerance of the replacement component in the equipment assembly; and determining that the target component is replaced successfully under the condition that the actual tolerance of the replaced component in the equipment assembly is less than or equal to the preset tolerance.
In short, after the target component is replaced by the replacement component corresponding to the second replacement data table, whether the replacement is successful or not can be identified by confirming the actual tolerance of the replaced component in the equipment assembly again, when the actual tolerance of the replaced component in the equipment assembly is smaller than or equal to the preset tolerance, the manufacturability design of the equipment assembly meets the production design requirement at the moment, when the actual tolerance of the replaced component in the equipment assembly is larger than the preset tolerance, the replacement failure is indicated, and the corresponding data needs to be sent to the engineering object for secondary confirmation.
In an exemplary embodiment, selecting a target program from a plurality of preset programs according to a device type of a device to be tested includes: receiving a setting instruction sent by an engineering object, wherein the setting instruction is used for selecting the type of replacing components of the equipment assembly; determining a first type corresponding to the setting instruction, and matching the first type with a second type set corresponding to a plurality of preset programs; and under the condition that the target second type matched with the first type exists in the second type set, determining the program corresponding to the target second type, and selecting the program as the target program.
