Problems solved by technology

In the actual production of PCB crimping holes, the design of the crimping hole is generally a single hole. The design structure of the single hole is relatively simple, without signal shielding function, and gradually cannot meet the requirements of high-speed transmission of signals in the crimping hole, and cannot achieve the effect required by customers.

Abstract

The invention relates to a method for manufacturing a PCB crimping hole. The method comprises the steps: acquiring a PCB, wherein the PCB comprises a first hole center coordinate, and the first hole center coordinate is a hole center position coordinate of a crimping hole; according to the first hole center coordinate, determining a second hole center coordinate, wherein the second hole center coordinate is the hole center coordinate of the shielding hole; according to the second hole center coordinate, carrying out the drilling on the PCB for the first time to obtain a first connecting hole, wherein the first connecting hole is a shielding hole to be processed; preprocessing the first connecting hole to obtain a second connecting hole, wherein the second connecting hole is a signal shielding hole; on the basis of the second connecting hole, carrying out the secondary drilling on the PCB according to the first hole center coordinate, and obtaining a crimping hole, wherein the second connecting hole intersects with the crimping hole. According to the scheme provided by the invention, the shielding hole has a signal shielding function, so that the signal transmission loss of the crimping hole is reduced, and the signal transmission efficiency of the crimping hole is improved.

Description

technical field [0001] The present application relates to the technical field of making crimping holes, in particular to a method for making PCB crimping holes. Background technique [0002] PCB printed circuit board (printed circuit board) is one of the important components of the electronics industry. Almost every electronic device, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, must use printed circuit boards. Board; With the development of various technical equipment, the quality requirements for printed circuit boards are getting higher and higher, especially for the signal transmission quality of PCB lines. [0003] The crimping hole is a special through hole on the PCB. It does not require soldering. It is a hole that can be fixed by inserting components directly. The crimping hole conducts current through the contact between the pin and the hole wall, thereby realizing signal transmission...
