Problems solved by technology
[0004] It is worth noting that in the prior art, since the method of removing solder paste is usually manual work, and the removal process is relatively troublesome, it is easy to cause the problem that the solder paste on the circuit board is not completely removed due to human error
When electronic components are bonded to these circuit boards, it will cause a short circuit on the circuit board or poor bonding between the electronic components and the circuit board.

Embodiment Construction
[0037] FIG. 1 is a schematic structural diagram of a cleaning device according to an embodiment of the present invention. Please refer to FIG. 1 , the cleaning device 100 can be used to remove a printed pattern 210 on a circuit board 200 . Wherein, the circuit board 200 is, for example, a printed circuit board (printed circuit board) with a plurality of pins (not shown), and the material of the printed pattern 210 is, for example, composed of particle metal (solder particle) and flux (flux). solder paste, but also includes conductive layer, photoresist layer, barrier layer or organic / inorganic solderability preservative layer printed on the circuit board and other materials. Furthermore, the printed pattern 210 is not correctly corresponding to these pins, for example. Therefore, the printed pattern 210 must be removed from a surface 220 of the circuit board 200 in order to reprint the correct printed pattern 210 .

The invention relates to a clearing device and a clearing method which are suitable for clearing a printing pattern on a circuit board. The clearing device comprises a platform, a vacuum type cleaning mechanism and a roller type cleaning mechanism. The platform is suitable for bearing the circuit board. The vacuum type cleaning mechanism is provided with a suction nozzle; and the suction nozzle is suitable for clearing partial printing patterns along a first direction. The roller type cleaning mechanism is provided with a cleaning roller, and the cleaning roller is suitable for clearing the residual printing patterns along the second direction. The clearing method or the clearing device can automatize the steps of clearing the printing patterns.
Description
technical field [0001] The present invention relates to a cleaning equipment (cleaning equipment) and a cleaning method using the cleaning equipment, and in particular to a printing pattern (printed pattern) suitable for cleaning a circuit board (print circuit board, PCB). ) removal equipment and the removal method using the removal equipment. Background technique [0002] At present, electronic elements are usually assembled on the circuit board by surface mount technology (SMT), so as to be electrically connected with the circuit board. The first step of the surface mount technology is to apply an appropriate amount of solder paste to the pins of the circuit board by printing. Moreover, the electronic components can be bonded to the circuit board only after confirming that the position and printing amount of the solder paste are correct, so as to avoid short circuit caused by the wrong position of the solder paste or too much or too little printing amount. [0003] In th...
