Abstract

The invention provides an efficient treatment method for improving drilling quality. The efficient treatment method comprises the following steps: A, designing a large-hole drilling belt or a long-groove drilling belt; B, controlling a base copper over 1.5 oz plate; and C, setting parameters of the grinding plate. The large hole drilling belt design comprises the steps that: A1, the diameter phi of a drilling hole is set, when the diameter phi is larger than or equal to 1.8 mm and smaller than 3.0 mm, four force unloading holes are formed, the hole distance is larger than or equal to 0.15 mm, and the diameter phi of the force unloading holes is 0.5-1.5 mm; A2, the hole diameter of a drill hole is set as phi, when phi is greater than or equal to 3.0 mm and less than or equal to 6.5 mm,four unloading forces are firstly drilled in the center, and then a large hole is drilled; A3, the hole diameter of the drill hole is set to be phi, and when the hole diameter is larger than 6.5 mm, a small hole reaming mode is adopted; and a G84 format reaming mode is adopted. According to the invention, through the design of the drilling belt, the generation of drilling burrs can be effectively reduced or avoided, and the generation of the drilling burrs is prevented from the source; the bottom copper 1.5 oz plate is managed and controlled in a differentiated manner, so that the process can be simplified and the efficiency can be improved on the premise of ensuring the quality; and through copper deposition plate grinding and setting of grinding plate parameters, hole burrs are obviously improved, and the undesirable condition of burrs is not found.

Description

technical field [0001] The invention belongs to the technical field of PCB processing, and in particular relates to an efficient processing method for improving drilling quality. Background technique [0002] With the rapid development of the information age, the cycle of technology replacement is getting shorter and shorter. At the same time, the application of automation and intelligence is becoming more and more concentrated and extensive. Especially for the manufacturing industry, due to the shortage of labor force and the rise of labor prices, the manufacturing industry needs to reorganize and reform the manpower and equipment. [0003] At present, the PCB board after conventional drilling is affected by the copper thickness of the board and the halogen structure. Usually, the upper part of the panel and the lower part of the bottom plate after drilling are passed through an abrasive belt grinder. The purpose is to clean the hole before copper plating. The batch front...
