[0003] Therefore, in order to meet the above requirements, you can add Route keepout-all area when creating screw holes within the range of screw holes. However, if you create Route keep out-all area, while avoiding non-gnd routing, gnd cannot be connected with The guard hole contact does not meet the relevant requirements of EE and EI

Abstract

The invention discloses an encapsulation mode of a screw hole. According to the encapsulation mode of the screw hole, an antipad and a regular pad are included, wherein the antipad is used for avoiding the contact between power wiring and an NPTH hole; the regular pad includes an outer ring and a second guard hole, wherein the outer ring surrounds first guard holes and the NPTH hole, and the second guard hole is connected with the outer ring; the second guard hole adopts a circular body to be connected with a GND. According to the encapsulation mode of the screw hole, the screw hole is set into the regular pad which is of a structure of which the ring is connected with the second guard hole; when the screw hole is connected to the ground, because the guard holes serve as the regular pad, the guard holes of the screw hole can be connected with the gnd, and the screw hole can also avoid a non-gnd; by the adoption of the antipad, power can be avoided, and the purpose of guard hole grounding is achieved, so that the screw hole avoids the technical problem of non-ground wiring.

Description

technical field [0001] The invention relates to the field of PCB design, and more specifically, relates to a packaging form of screw holes. Background technique [0002] In PCB design, each layer has corresponding requirements for assembly screw holes, especially the inner layer. For example, in order to avoid burning the board caused by the screw hole grinding the surrounding lines when assembling the screw, and to prevent the PCA factory from fooling, it is necessary to ensure that the wiring and power are far away from the screw hole; in addition, in order to meet the requirements of EE and EI, the guard hole of the screw hole must be ensured grounded. [0003] Therefore, in order to meet the above requirements, you can add Route keepout-all area when creating screw holes within the range of screw holes. However, if you create Route keep out-all area, while avoiding non-gnd routing, gnd cannot be connected with The guard hole contact does not meet the relevant requireme...
