Problems solved by technology

[0004] Due to the matching characteristics of the nozzle and the ink during the printing process and the effectiveness of the maintenance operation of the nozzle, some of the nozzles of the nozzle may be blocked, so that the printed pattern may be disconnected. The printing quality will not be greatly affected, but due to the functional requirements of the printed circuit board itself, the final pattern formed by spray printing cannot have broken lines, and there is no simple and easy way to print the printed circuit board at present. method can solve this technical problem

Embodiment 1

[0022] see figure 1 , the nozzles are arranged with 6 nozzles in 360dpi (that is, there are 360 ​​nozzles in 1 inch length) physical resolution, that is, the nozzle hole distance d is 1 / (360-1) inches.

[0023] The trajectory of the nozzle movement is shown by the arrow line:

[0024] Step1: Print one inch along the positive direction of scanning, and scan out 360×6 matrix points;

[0025] Step2: Move along the stepping direction D=(6-1)×d / 2 or 2.5d;

[0026] Step3: Print one inch along the opposite direction of scanning, and scan through dot insertion, the resolution of the stepping direction of the cross section reaches 720dpi;

[0027] Step4: Move the nozzle along the stepping direction D;

[0028] Repeat the above process, that is, the uniform stepping of the insertion point and the bidirectional scanning mode, to complete the printing process of the printed circuit board.

Embodiment 2

[0030] The same nozzle, the difference is that each step distance D=(6-1)×d / 3, and finally realized the step direction resolution of 1080dpi.

Abstract

Relating to the technical field of printed circuit board jet printing, the invention provides a printed circuit board jet printing motion scanning method, which adopts an insertion point type uniform stepping mode. The technical scheme does not add any cost or extra jet printing process on the basis of current printed circuit board jet printing equipment. In other words, under the premise of ensuring both the cost and the efficiency, by means of simple parameter adjustment, an obvious disconnection problem caused by clogging of a part of nozzles can be effectively avoided. At the same time, the resolution of a jet printing pattern can be improved manyfold according to needs conveniently. The method has a simple principle, is easy to popularize, and can obtain smooth graphics with consistent jet printing quality.

Description

technical field [0001] The invention relates to a printed circuit board jet printing technology, in particular to a printed circuit board jet printing movement scanning method. Background technique [0002] The printing core component of a printed circuit board inkjet printer is called a nozzle. There are many extremely small holes on the nozzle, called nozzles, and the ink is ejected at high speed from the nozzles during printing, forming an image on the circuit board. [0003] The movement of the nozzle includes a scanning direction and a stepping direction, the scanning direction is perpendicular to the nozzle arrangement direction, and the stepping direction is parallel to the nozzle arrangement direction. If the nozzle prints in both forward and reverse scanning directions, it is called bi-directional scanning mode, and if the nozzle moves the same distance each time in the step direction, it is called uniform stepping mode. The movement mode and distance in the step ...
