Abstract

The invention provides a plugging device which is used for plugging a through hole in a circuit substrate. The circuit substrate has an upper surface and a lower surface which are opposite, and the through hole penetrates through the upper surface and the lower surface. The plugging device comprises a conveying device, a coating device, a gas sucking and ink guiding device and an ink removing device, wherein the conveying device is used for conveying the circuit substrate to enable the circuit substrate to sequentially pass through the coating device, the gas sucking and ink guiding device and the ink removing device; the coating device is positioned above the conveying device and is used for coating a plugging material on the upper surface of the circuit substrate conveyed by the conveying device; the gas sucking and ink guiding device is positioned below the circuit substrate conveyed by the conveying device, is in contact with the lower surface of the circuit substrate, and is used for enabling the plugging material on the upper surface of the circuit substrate to enter the through hole by gas suction; and the ink removing device is positioned near the circuit substrate conveyed by the conveying device, and is used for removing the plugging material on the upper surface of the circuit substrate after plugging. The invention also relates to a method for plugging the circuit substrate by adopting the plugging device.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a plugging device used in the circuit board production process and a method for plugging holes in a circuit substrate using the same. Background technique [0002] With the advancement of science and technology, printed circuit boards have been widely used in the electronic field. For the application of the circuit board, please refer to the literature Takahashi, A.Ooki, N.Nagai, A.Akahoshi, H.Mukoh, A.Wajima, M.Res.Lab, High density multilayer printed circuit board for HITAC M-880, IEEE Trans. on Components, Packaging, and Manufacturing Technology, 1992, 14(4): 418-425. [0003] In the actual production process of the circuit board, a via hole needs to be formed between the two conductive layers of the circuit board, so that the subsequently formed two-layer conductive lines are electrically connected to each other. The via hole is usually formed by the follow...
