Abstract

The invention discloses a method for processing PTH connecting hole burrs. The method for processing the burr in the PTH connecting hole includes the following steps: drilling at the reserved position of hole A; drilling at the reserved position of hole B, and the intersection of hole B and hole A forms a connecting hole; step S3: Drill again at the same position to form hole C, and the shape and size of hole C are the same as hole A. The method for treating the burr of the PTH connecting hole provided by the invention has a simple process, and the product has no burr phenomenon after being washed with water and electroplating.

Description

technical field

[0001] The invention relates to the technical field of printed circuit board production, in particular to a method for processing PTH connecting hole burrs. Background technique

[0002] PCB (Printed Circuit Board, printed circuit board) is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. PTH (Platating Through Hole, metallized hole) is generally provided on the PCB, and copper is provided inside the hole to realize electrical conduction.

[0003] With the technological development of the electronics industry, in order to meet customer requirements, the PTH holes in PCB boards are often required to be designed as connecting holes. The intersection of holes and holes will produce burrs, which are obvious after electroplating. In order to solve the problem of burrs in PTH connecting holes, in the existing technology, the technical means of reducing the number of stacked p...
