Board edge graphical tool manufacturing method preventing electrostatic spraying board from falling off

Abstract

The invention discloses a board edge graphical tool manufacturing method preventing an electrostatic spraying board from falling off. The method comprises the following steps of A, cutting a copper-clad board, forming a multilayer circuit board through manufacturing an internal graph, laminating, drilling and electroplating the copper-clad board, or forming a single-double-sided circuit board through drilling and electroplating the copper-clad board; B, manufacturing an external board graph of the multilayer circuit board or a Film picture which transfers the graph of the single-double-sided circuit board, wherein a circuit graph located at a middle part and a board edge stripe graph located at an external border are on the Film picture; C, pasting a dry film on the external board of the multilayer circuit board or on the upper and lower sides of the single-double-sided circuit board, para-pasting the Film picture on the dry film, performing exposure and development, transferring the circuit graph to the middle region of a circuit board substrate, and transferring the board edge stripe graph to the board edge external border of the circuit board substrate; and D, etching the circuit board substrate to manufacture the circuit board with board edge stripes on the external border. Compared with the prior art, the board edge graphical tool manufacturing method disclosed by the invention prevents the phenomenon of board falling, and simultaneously, the efficiency of electrostatic spraying is improved.

Description

Technical field: [0001] The invention belongs to the technical field of printed circuit board production, and specifically relates to a method for producing a board edge graphic tool to prevent electrostatic spraying from falling off the board. It is mainly used to solve the problem of ensuring the efficiency of electrostatic spraying of circuit boards in the current electrostatic spraying process Avoid the problem of board falling due to the fact that the edge of the circuit board is too smooth, resulting in the clip not being able to clamp and fix it tightly. Background technique: [0002] Printed circuit board is the most important basic electronic component in the electronics industry, and it has a wide range of applications in computer, communication, consumer electronics, industry, medical and military fields. With the development of science and technology and the continuous improvement of circuit board quality requirements, inkjet technology has gradually emerged in t...
