Problems solved by technology

[0004] At present, in the process of making circuit boards by drilling substrates, there are often bad situations where the inner holes of the substrates are blocked. One of the main reasons for this problem is that the cutting powder generated during drilling remains in the inner holes. That is, the cutting powder has not been removed in time

Abstract

The invention belongs to the technical field of electronic device manufacturing, and particularly relates to a circuit board processing method. The circuit board processing method comprises the following steps of A, material opening, in which a large copper plate is cut into a plurality of small copper plates; B, inner-layer film formation, in which a dry film is attached onto the copper plate andis exposed by ultraviolet ray; C, internal etching; the exposed copper plate is placed in an alkali solution; D, brownization, composition and plate pressing to obtain a substrate; and E, drilling, in which a drilling device is arranged to drill, wherein the drilling device comprises a rack, a drilling mechanism and a dust removal mechanism, the drilling mechanism comprise a motor, a rotation wheel, a sliding block, a mobile rack, a support block, a sliding rod and a drilling head, and the dust removal mechanism comprises a main oscillating rod, a straight rod, a dust removal piston and a dust removal chamber. With the circuit board processing method disclosed by the technical scheme, cutting powder in holes in the substrate can be effectively removed, and inner hole plugging is prevented.

Description

technical field [0001] The invention belongs to the technical field of electronic device manufacturing, and in particular relates to a circuit board processing method. Background technique [0002] The circuit board (PCB) plays the role of the connection function in the entire electronic product, and when the function of the electronic product fails, the PCB is often the first to be suspected, and because the processing technology of the PCB is relatively complicated, so the PCB Production control is particularly strict and important. [0003] The production process of PCB is mainly divided into eight parts: inner layer circuit, lamination, drilling, hole metallization, outer layer dry film, outer layer circuit, silk screen, surface process and post process. The inner layer circuit specifically includes material cutting, inner layer film, inner etching, browning, typesetting, pressing plate, drilling and copper sinking. [0004] At present, in the process of making circuit...
