preparation example Construction

[0050] The embodiment of the present invention provides a preparation method of drilling ink, comprising the following steps:

[0051] S1. Provide modified acrylic resin, UV monomer, photoinitiator, color paste, filler, and auxiliary agent according to the above-mentioned drilling ink formula;

[0052] S2. Mix the modified acrylic resin, UV monomer, photoinitiator, color paste, filler and auxiliary agent to obtain the drilling ink.

[0053] Preferably, in the present invention, each component in S2 is added sequentially in the following order: photoinitiator, UV monomer, auxiliary agent, modified acrylic resin, filler, color paste; among the above components, each component should be added before adding Ensure that the aforementioned components are fully dispersed and evenly distributed. The dispersibility of the drilling ink obtained in this way is better, and it is easier to obtain a smooth and flat ink film when applied to the surface of the printed circuit board to be dri...

Embodiment 1

[0066] A kind of drilling ink, its preparation method comprises the steps:

[0067] (1) Stir and dissolve the photoinitiator in the UV monomer, and then evenly disperse the auxiliary agent in it;

Abstract

The invention belongs to the technical field of electronic materials, and particularly relates to drilling ink and application thereof. The drilling ink is prepared from the modified acrylic resin, a UV monomer, a photoinitiator, color paste, a filler and auxiliaries, an ink film formed after the drilling ink is cured has high hardness, the drilling ink can replace a traditional cover plate to be used for drilling in the drilling process of the printed circuit board, the ink film can be simply removed through laser and other methods after drilling is completed, and the drilling efficiency and the drilling precision can be remarkably improved. Meanwhile, due to the fact that traditional aluminum sheets, cold punching plates and the like are not used as cover plates, the production cost can be reduced, and the problems that chippings wind a cutter and the like can be solved.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a drilling ink and an application thereof. Background technique [0002] In the printed circuit board (referred to as PCB) processing and manufacturing process, affected by many factors such as materials, structural design, circuit design, pressing process and equipment, the PCB board processed by the pressing process will have a certain degree of deformation, and it will be placed on a flat surface. There are different degrees of warping deformation on the marble platform. The warping deformation of the PCB board has a great influence on the drilling process. If the PCB board is thin (below 3.0mm), the drilling position of the PCB board can be changed by appropriately increasing the pressure of the pressure foot during drilling. The warping deformation makes the PCB board and the backing board close together, and the drilling will not produce excessive ...
