And S4, ending.
More specifically, in step S31, the tolerance of the drilled hole is automatically corrected by a program, specifically, the drilled hole is searched according to the type and the aperture on the PCB board of the design software by a program coding function, the tolerance of the drilled hole is determined, and a corresponding modification is automatically made. Referring to the schematic diagram of the drilling table shown in fig. 2, the implementation process is as follows according to the Type and the platinum aperture in the drilling table:
1) the Type classifies the borehole as circular drill/over slot/explicit hole, the program auto query is for that borehole Type, and then makes corresponding modifications to the tolerances, e.g., All explicit holes size tolerance is +/-5 mil;
2) the platinum aperture is divided into PTH/NPTH, the program automatically queries which aperture is, and then makes corresponding modifications to the tolerances, e.g., NPTH size 198mil or more gan 198mil, the tolerance is +/-5 mil.
Further, in step S32, automatically highlighting and labeling the Press fit part specifically includes:
searching a Press fit part on a PCB of design software according to the part attribute through a program coding function, automatically highlighting the Press fit part and reporting related drilling information, wherein the drilling information report is shown in FIG. 3;
according to the reported drilling information of the Press fit part, the drilling size corresponding to the Press fit part is found in the generated drilling table, and the Press fit labeling is carried out in the generated drilling table, as shown in FIG. 4.
Because the Press Fit mode is suitable for crimping tool parts, generally many PINs, the hole on the PCB is very small, the PIN needs to be directly pressed into the hole through a Press-fitting machine, the angle and the pressure need to be strictly controlled, and the requirements on the PCB are high, the detection is complex and the process manufacturing requirements are strict. By the method, the Press fit part can be highlighted quickly, and the corresponding characters are added into the drilling table, so that the time of a design engineer and the omission of manual searching are greatly reduced.
