Abstract

The invention relates to a circuit board and a printing method thereof. The printing method of the circuit board is used for printing the circuit board with a recession in the surface, and comprises the following steps: printing on the recession of the circuit board and the peripheral area of the recession in a manner of ink-jet printing, wherein during printing, the environment temperature is 16-24 DEG C, and the environment humidity is 40-80%; the ink-jet air pressure is 0.3-1.0MPa, the ink-jet thickness of 0.1-10mm, and the ink-jet line width is greater than 50[mu]m. The printing is carried out in the manner of ink-jet printing, and ink can be injected to the bottom of the recession under the action of a pressure at the recession of the circuit board, so that the problem that oil discharge cannot be carried out is solved. Clear printing, high continuity and good printing effect are achieved under the parameter conditions that the environment temperature is 16-24 DEG C, the environment humidity is 40-80%, the ink-jet air pressure is 0.3-1.0MPa, the ink-jet thickness of 0.1-10mm, and the ink-jet line width is greater than 50[mu]m.

Description

technical field [0001] The invention relates to the technical field of circuit board manufacturing, in particular to a circuit board and a printing method thereof. Background technique [0002] Generally, the characters on the circuit board are formed on the circuit board by the traditional printing method, that is, a text screen is set on the circuit board, and the characters are printed by a scraper. [0003] If the circuit board is uneven and has a sunken position, such as a soft-hard board, the soft board is sunken relative to the whole. At this time, the sunken position is not accepted under the screen, and oil cannot be applied, and the printing effect is poor. Contents of the invention [0004] Based on this, it is necessary to provide a circuit board with uniform printing and good effect and a printing method thereof to solve the above problems. [0005] A circuit board printing method, used for printing a circuit board with depressions on the surface, comprising ...
