Problems solved by technology

Regarding the related technologies mentioned above, the applicant believes that after the MLB is updated and iterated, the distribution of the test points on the MLB will also change, and in order to achieve the same ICT or FCT detection purpose, the fixture supplier needs to target the customer’s product The updated version of MLB on the motherboard needs to redesign the fixture. This redesign process is labor-intensive and time-consuming, and will increase additional material costs. With more and more versions of MLB update iterations, the difficulty of redesign and The cost of manpower and material resources will also increase, resulting in higher maintenance costs for later modification of the fixture, which will affect the developability of the fixture

Embodiment 1

[0101] The embodiment of the present application provides a method for designing a hole position of a printed circuit board inspection jig, and the main process of the method is described as follows.

[0102] refer to figure 2 ,

[0103] S1. Acquire an actual point TPx corresponding to the detection point of the current printed circuit board, generate an actual set including all actual points TPx, and preset a minimum spacing value Dmin.

[0104] Among them, the detection point is a point that MLB needs to detect in ICT detection or FCT detection, and the actual set is a set including all actual points TPx. Since each actual point TPx corresponds to each detection point of the current MLB, the acquisition of the actual set is equivalent to the preset distribution of each detection point on the fixture, and the needle carrier board of the later fixture can be printed according to the distribution of each actual point TPx. The hole positions corresponding to the detection poi...

Embodiment 2

[0271] refer to Figure 13 , in one embodiment, a hole position design device for a printed circuit board inspection jig is provided, which corresponds to the hole position design of the printed circuit board inspection jig in the above-mentioned first embodiment. The modification and maintenance cost of the fixture in the later stage improves the developability of the fixture. The device includes an actual generation module 1, a potential derivative module 2, an interference elimination module 3, a combined new module 4, a final generation module 5 and a hole output module 6. The detailed description of each functional module is as follows:

[0272] The actual generation module 1 is used to obtain the actual point TPx corresponding to the detection point of the current printed circuit board, and generate an actual set containing all the actual points TPx; and,

[0273] The latent derivation module 2 is used for generating a number of potential points Pn based on the coordina...

Embodiment 3

[0279] In one embodiment, an intelligent terminal is provided, which includes a memory, a processor, and a computer program stored on the memory and executable on the processor, wherein the memory stores training data, algorithm formulas, and filtering mechanisms in a training model Wait. The processor is used to provide computing and control capabilities, and the processor implements the following steps when executing a computer program,

[0280] S1. Obtain the actual point TPx corresponding to the detection point of the current printed circuit board, and generate an actual set containing all the actual points TPx;

[0281] S2. According to the potential derivation strategy, several potential points Pn are generated based on the coordinates of each point in the actual set, and an initial set containing all the potential points Pn is generated;

[0282] S3, according to the interference exclusion strategy, based on each point in the actual set and the preset forbidden area mo...

Abstract

The present application relates to a hole position design method, device and system for a fixture for printed circuit board inspection, which includes S1, obtaining actual points corresponding to the inspection points of the current printed circuit board; S2, generating Several potential points; S3. Generate a second reserved set according to the interference exclusion strategy; S4. Generate new points according to the merge new strategy; S5. Generate a final reserved set based on the current second reserved set; S6. Obtain several A reserved hole corresponding to each point in the final reserved set, and several reserved holes corresponding to each actual point are obtained. The application has the effect of reducing the later modification and maintenance cost of the jig and improving the developability of the jig.

Description

technical field [0001] The present application relates to the field of printed circuit board inspection jig design, and in particular to a method, device and system for hole position design of a printed circuit board inspection jig. Background technique [0002] With the development of the electronic industry, the requirements for the reliability of the electronic system are also getting higher and higher. In the mass production of printed circuit boards, in order to ensure that the circuit boards that leave the factory meet the corresponding specifications or parameter requirements, manufacturers usually The end of the printed circuit board inspection equipment is added to ensure the appearance quality of the printed circuit board, especially in the production of MLB (multi-layer printed board). Common printed circuit board inspections include ICT (on-line test) and FCT (functional test). Whether it is ICT inspection equipment or FCT inspection equipment, there will be seve...
