Problems solved by technology

[0004] Since the pad spacing between the two crimping holes is fixed, the number of signal lines that can pass through the pad spacing between the two crimping holes is certain. When the wiring density of the PCB is getting higher and higher, obviously, The signal lines that can pass through the pad spacing between the two crimp holes cannot meet the wiring density requirements

Embodiment Construction

[0028] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a PCB manufacturing method, which is used to make crimping holes in the PCB, such as figure 2 As shown, the method includes the following steps:

[0029] Step 201 , at the position of the crimping hole to be processed on the PCB, a through hole as an initial crimping hole is processed, and the diameter of the initial crimping hole is smaller than that of the crimping hole to be processed.

[0030] Wherein, the crimping hole to be processed is the crimping hole that needs to be processed in the prior art. The crimping hole of PCB is divided into crimping side and non-crimping side, such as Figure 3A-Figure 3D As shown, it is a schematic diagram of the processed through hole as the initial crimping hole. The diameter of the initial crimping hole on the crimping side is consistent with the diameter of the initial crimping hole on the non-crimping side, and the initial crim...

Abstract

The invention discloses a method for manufacturing a PCB and a PCB. The method comprises: processing the position of a crimping hole to be processed on the PCB to obtain a through hole as an initial crimping hole, and the diameter of the initial crimping hole is smaller than the to-be-processed hole. The aperture of the crimping hole; on the crimping side of the PCB, the initial crimping hole is expanded and drilled to obtain a crimping hole of a preset depth, and the aperture of the crimping hole of the preset depth is equal to the crimping hole to be processed The aperture of the hole; the metal plating process is performed on the initial crimping hole on the non-crimping side of the PCB and the crimping hole of the preset depth to make the crimping hole in the PCB. In the embodiment of the present invention, the wiring density can be increased, the wiring space of the crimping pins can be increased, and the wiring capability can be enhanced.

Description

technical field [0001] The invention relates to a manufacturing technology of a printed circuit board (PCB), in particular to a PCB manufacturing method and the PCB. Background technique [0002] The technology of connecting the crimping device and PCB (Printed Circuit Board, printed circuit board) by crimping, its working principle is: design crimping pins (ie crimping pins) that can be deformed by force on the crimping device ), when the crimping pin is pressed into the crimping hole of the PCB, the crimping pin is squeezed by the wall of the crimping hole, deformed and attached to the wall of the crimping hole of the PCB, so as to achieve effective connect. [0003] In the existing technology, such as figure 1 As shown, the crimping hole of the PCB is divided into crimping side and non-crimping side. The crimping pin will be pressed into the crimping hole of the crimping side, and the crimping pin will not be pressed into the crimping hole of the non-crimping side. pin...
