Embodiment 1
[0048] This example provides a method for printing characters of multiple colors on the same side of a printed board, which is carried out after the solder resist step of the printed board. The process is as follows figure 1 shown, including the following steps:
[0049]S1: Use a text inkjet machine to jet the first color character ink at a designated position on one side of the printed board. Specifically, first retrieve the file that needs inkjet white text, use the CCD to first grab the Mark points at the four corners of the board to position and automatically adjust the position, and then use the PCB text inkjet machine to spray white text ink according to the corresponding position of the file on the printed board Ink, can use model IJR-4000MW300 to carry out.
[0050] S2: pre-curing the character ink of the first color by using UV or the like.
[0051] The pre-curing parameters are: curing at 75°C for 30 minutes, then curing at 90°C for 30 minutes, then curing at 120°C...
Embodiment 2
[0089] This example provides a printing board manufacturing method for printing characters of multiple colors on the same side, including steps:
[0091] According to the requirements of the engineering data MI, the large sheets that meet the requirements are cut into small pieces for production until they become small pieces that meet the customer's requirements. Process: large plate→cutting according to MI requirements→curling plate→beer fillet edge grinding→out the plate.
[0092] (2) Drilling.
[0093] According to the requirements of engineering data, drill the required hole diameter at the corresponding position on the board that meets the required size. Process: Stacking plate pins → upper plate → drilling → lower plate → inspection and repair.
[0096] A thin layer of copper is chemically deposited on the walls of the insulating hol...
Embodiment 3
[0115] A printed board with characters in multiple colors printed on the same side in this example is obtained by the method for making a printed board with characters in multiple colors printed on the same side in Embodiment 2.

Abstract
The invention provides a method for printing characters of various colors on the same surface of a printed board and a printed board manufacturing method. The method for printing the characters of thevarious colors comprises the following steps that S1, first color character ink is jetted at a specified position on one surface of the printed board; S2, the first color character ink is pre-cured;S3, the printed board is aligned with a graphic silk screen by using the graphic silk screen required by the second color characters; S4, second color character ink is poured onto the graphic silk screen, printing and oil returning are started, and the printed surface with the first color characters being pre-cured is made to present the second color character ink; S5, the second color character ink is cured, and the characters of two colors are printed on the same surface of the printed board; And more colors are printed, additive printing of characters of the next color is carried out according to the steps from S3 to S5. The characters of the various colors can be manufactured / printed on the same surface of the printed board, identifications of different types of devices can be distinguished, the finally-obtained printed board has characters / identifications of more than two colors, and the application range is wide.
Description
technical field [0001] The invention relates to the field of circuit boards, in particular to a method for printing characters of multiple colors on the same side of a printed board, a method for manufacturing the printed board and the printed board. Background technique [0002] Printed characters on the printed board are used to identify the position of components and identify the direction of characters. [0003] Existing printed board or circuit board, the character on its surface has only a kind of color, or just only print white, or just only print black or other colors. [0004] With the increase of the wiring density of the printed board, the function becomes more powerful, and the types of electronic components are more and more. In order to reduce the component placement error and visual management of the components on the printed board, it is necessary to pass the same Print different character colors on the positions of different types of devices on the surface,...
