Embodiment Construction

[0025] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0026] As mentioned above, in the prior art, after the through-holes are drilled on the epoxy gas-permeable panels, the tiny joints are easy to break and generate debris, which affects the quality of the plug holes and the cleanliness of the purification workshop. After drilling through holes, there will be local voids in the air-permeable board, which will have a great impact on the support of the printed board surface when the holes are plugged, and the force on the board surface will be uneven when the plug holes are scraped (see the profile Figure 5 ), when the resin plugs the hole, there will be some problems that the plug cannot be partially plugged, and too much oil will be emitted locally.

Abstract

The invention provides a printed board open hole printing ink filling method and a hole filling breathable board. The printed board open hole printing ink filling method includes the following steps that the hole filling breathable board is manufactured, a blind hole corresponding to an open hole to be filled in a printed board is formed in a resin base material board, wherein the blind hole does not penetrate through an epoxy base material board, and the aperture of the blind hole in the breathable board is larger than the aperture of the corresponding open hole to be filled in the printed board; the boards are stacked, wherein the resin base material board provided with the blind hole, the printed board provided with the open hole to be filled and a hole filling template provided with an opening corresponding to the open hole to be filled are sequentially arranged on a machine table in an aligning mode; filling of printing ink is performed, wherein the printing ink is pushed to the other side of the open hole to be filled from one side of the open hole to be filled, and therefore the open hole to be filled can be filled with the printing ink.

Description

technical field [0001] The invention relates to the field of integrated circuit manufacturing, and more specifically, the invention relates to a method for filling ink in the holes of a printed board and a plug hole gas-permeable plate used in the method for filling the ink in the holes of the printed board. Background technique [0002] The plug hole manufacturing process is widely used in the printed board industry, such as solder resist ink plug holes, resin plug holes, conductive paste plug holes, etc. The quality of the plug holes is related to the reliability of the printed board. The air-permeable plate is not the main factor affecting the quality of the plug hole, but a good use of it is of great help to improve the quality of the plug hole. [0003] The effect of the plug hole vent plate is that the ink 60 is inserted into the hole of the printed board 30 through the plug hole template 40 to facilitate the removal of the air in the hole (generally scrape the ink 60 ...
