Problems solved by technology

[0005] The embodiment of the present invention provides a circuit board refueling device, which is used to solve the problem in the prior art that the PCB board is in contact with the atmosphere so that the hole contains air, and the gap between the ink inserted during manual refueling and the ink already present in the via hole is solved. Wrapped with air, the fluidity of the ink is poor, and it is difficult to completely fill the via hole due to the obstruction of the air

Abstract

A circuit board oil replenishing device provided by an embodiment of the present invention includes a vacuum cover arranged on the peripheral circuit board of the target hole and an air extraction device communicated with the vacuum cover; The control device for on-off of the oil pipeline, the oil injection pipeline includes an oil injection port arranged in the vacuum cover, and the oil injection port faces the target hole. By covering the peripheral circuit board of the target hole to be filled with ink, a vacuum cover is formed between the vacuum cover and the circuit board to form a sealed cavity connected with the target hole, and the air suction device extracts the air in the sealed cavity, and correspondingly, it also sucks the air in the sealed cavity. Take the air in the target hole, reduce the vacuum in the hole, and the ink will no longer be blocked by the air in the hole when plugging, and it is easier to enter the inside of the target hole and fill the unfilled target hole, which is beneficial to provide circuit board plugging Work efficiency, and improve ink plug hole quality.

Description

technical field [0001] The invention relates to the technical field of printed circuit board manufacturing, in particular to a circuit board oil replenishing device. Background technique [0002] With the development of Printed Circuit Board (PCB) technology and the evolution of product complexity, PCB boards have developed to the design and application of multilayer boards. For connection, there are via holes penetrating the board surface on the PCB, and the hole walls of the via holes are provided with conductive materials such as copper materials, etc., and the circuits on the unit boards of each layer are connected through the conductive materials on the via holes. [0003] Since the circuit board must go through the etching process in the production process, the metal material on the wall of the via hole is eroded and damaged by the etching solution. Therefore, the prior art is to fill the conductive hole with ink for plugging, so that An anti-corrosion material is for...
