technical field

The invention relates to the technical field of EDA, in particular to a method for resetting device bit numbers in a PCB.

Background technique

With the continuous development of electronic information technology, the complexity of PCB design is increasing, and there are more and more devices on the PCB. In addition to revisions and other reasons, it often causes discontinuous part numbers of board components and some large part numbers. In the principle, it is too troublesome to modify the part numbers one by one, and it will also cause the rework of some PCBs, increase the workload of principle design and PCB design, and delay the development progress. If it is not modified, the silk screen printing with large numbers will occupy the space of the board, which is not conducive to the arrangement of BOM devices, and the board will not be beautiful. How to design PCB with high speed and high quality has also become an issue that layout engineers are more and more concerned about.

detailed description

In order to make the purpose, technical solution and advantages of the present invention clearer, a method for resetting device tag numbers in a PCB according to the present invention will be further described in detail in conjunction with specific embodiments below.

The present invention proposes a method for resetting device tag numbers in PCBs, which can reset device tag numbers without changing the PCB and the principle logic relationship, and can adjust the large and discontinuous tag numbers appearing in the PCB. Save the board space occupied by the silk screen printing of device tag numbers, sort out the sequence of tag numbers, make the device BOM table more intuitive, help device BOM sorting, and help save space on the PCB board, making the PCB board more beautiful and practical.

Example:

This embodiment describes a method for resetting component bit numbers in a PCB. On the premise of not changing the PCB and the principle logic relationship, the component bit numbers in the PCB are sorted, and the large bit numbers and discontinuous numbers appearing in the PCB are sorted. The bit number is adjusted, and the discontinuous bit number and large number bit number in the PCB are removed, so that the device BOM table is more intuitive, the PCB saves space, is more beautiful and meets the design requirements.

The device tag reset method in the PCB described in this embodiment, as shown in Figure 1, the specific steps of the device tag reset method in the PCB include: 1. The components in the PCB are classified according to the tag: resistance class R, Capacitor type C, chip type U, etc.; 2. The resistor type number is checked and adjusted according to the algorithm, the capacitor type number is checked and adjusted according to the algorithm, and all component types that need to be checked and adjusted are adjusted according to the algorithm in turn; 3. Operation of the front label of the schematic diagram , Complete the exact sameness between the PCB and the schematic diagram, and keep all other attributes unchanged; 4. After the adjustment, remove the discontinuous bit numbers and unnecessary big bit numbers in the PCB.

The method for resetting the device tag number in the PCB described in this embodiment is described below with a specific implementation process:

1) The device bit numbers in the PCB are classified according to the category, generally with the initial letter of the bit number, such as resistor R, capacitor C, inductance L, etc.;

2) Check the resistance R components one by one, for example: for the resistance components whose number starts with R, start checking from R1, R1, R2, R3...Ri, Ri+1, Ri+2...Rj , Rj+1, Rj+2...R is the largest, if there is no Ri in the inspection, then Ri+1 is changed to Ri, Ri+2 is changed to Ri+1, Rj is changed to Rj-1, Rj+1 is changed to Rj... ..., and so on, until no discontinuous bit number appears to terminate;

3) Check and adjust other types of devices in the PCB in turn, such as capacitors, inductors, diodes, triodes, magnetic beads, MOS, connectors, chips, etc., each type of device is checked and adjusted according to this algorithm;

4) After the PCB device classification and adjustment are completed, perform the pre-standard operation from the PCB to the schematic diagram, and complete the synchronization between the schematic diagram and the PCB after the pre-standard;

5) During the adjustment process, only the bit number is changed, all connections and other attributes in the PCB will not be changed, and all discontinuous bit numbers and large bit numbers have been adjusted.
