The first step in the surface adhesion technique is to apply an appropriate amount of solder paste to the pins of the board in a printed manner. Moreover, it is necessary to confirm that the position and the amount of the solder paste are all in the same state. The electronic components can be transferred to the circuit board to avoid the problem of tin (four) position error or the amount of printing (four) or too little. If a small amount of tin enamel is printed incorrectly by equipment or a person, it is usually manually removed by hand to remove the zipper θ by hand, and if there is a large amount of teeth or small scratches, it is judged that there are more The tin paste is printed on the poor of Wu. However, when the board is used to clear the circuit, it usually cleans the entire board and reprints the solder paste. And then, after cleaning, it is worth noting that m-one industry clears '200922390 _. - '-^ltwf.doc/n Easy to cause human error due to human error and electronic components are connected to these circuits (4), , 贞] / 3 in addition to the complete problem.

The above described features and advantages of the present invention will be more apparent from the following description. [Embodiment] FIG. 1 is a schematic structural view of a cleaning device according to an embodiment of the present invention. Referring to FIG. 1, the cleaning device 100 can be used to erase one of the printed patterns 210 on a circuit board 200. The circuit board 2 is, for example, a printed circuit board (printed circuit b〇ar(j) having a plurality of pins (not shown), and the material of the printed pattern 210 is, for example, a particulate metal (s〇ider partjcie). And solder paste composed of flux, but also includes a conductive layer, a photoresist layer, a barrier layer or an organic layer printed on a circuit board. Further, the printed pattern 210 is, for example, incorrectly corresponding to the pins. Therefore, the printed pattern 210 must be on the surface 220 of one of the circuit boards 2 Cleared to facilitate reprinting of the correct printed pattern 210. The cleaning apparatus 100 has a vacuum cleaning mechanism 140 and a roller cleaning mechanism 150, and the vacuum cleaning mechanism 140 moves, for example, with a suction nozzle 142 along a first direction X. Or driving the circuit board 200 relative to the suction nozzle 142 in the first direction X by a platform 110 to remove the printed pattern 210 on the first direction 。. Further, the 'roller cleaning mechanism 15 〇 One (71 twf.doc/n 200922390 cleaning wheel 152 is rolled in the second direction, or is a printed pattern in the second direction y of the platform (10) road board 200 relative to the cleaning wheel 152 along the 笫 士In the embodiment, the platform 100 is, for example, a χγ γ-axis guide, and can be used to carry the circuit board 200. The ten-m lead screw 112 is rotated to drive the Hi120. The driving mechanism 110 is moved along a first vacuum cleaning mechanism 140. The driving mechanism 130: is adapted to rotate the other lead screw 1H of the movable platform 110 to drive the platform i to reduce the second square center The roller type cleaning mechanism i5G moves. The first direction X is substantially perpendicular to the second direction y. /, 丫 14), and the vacuum cleaning mechanism has, for example, a long strip of nozzles for the second person to suck in the first - the printed pattern 120' in the direction X and the wheeled cleaning rhyme 15G has, for example, a long strip (four) clear 152 ^ = a print pattern 12 ( ) that is sexually adsorbed in the second direction y. The cleaning wheel (5) 2 = one One of the directions x rotates the shaft 154, and the roller cleaner l ^ is placed on the surface of the cleaning 152 - (9) Attachment material ^. wherein the suction layer is, for example, a non-woven fabric, and the solvent for removing the solder paste is not woven. The manner of using the cleaning device/month to remove the printed pattern 21 on the surface 220 of the circuit board 200 will be described below. The circuit board 200 is disposed on the platform 11 = = 20 to drive the flat vacuum along the first direction: the structure 140 is moved so that the nozzle 142 is along the first direction = face =. At this time, the suction nozzle 142 can remove the printed pattern 210 on the surface of the board by suction. Then, the drive mechanism 13 is turned on. The driving stage 200922390 71 twf.doc/n stage 110 is moved relative to the roller type cleaning mechanism 150 in the second direction y to move the cleaning wheel 152 in the opposite direction of the second direction. At this time, the month λ "the wheel 152 can leave the brush pattern 210 by the cleaning of the adsorbing material layer on the surface 156 and the surface 22G of the solvent/month removing circuit board 2GG due to the cleaning of the nozzle 142. Then, the driving mechanism 13 is further driven to move relative to the roller cleaning mechanism 15 in the opposite direction of the second direction 7 to repeat the surface 22 of the circuit board 2 to the printed pattern 21 〇 Completely cleared. 〃 ζ\ As can be seen from the above embodiments, the present invention can automate the step of removing the printed pattern to avoid the problem of incomplete removal of the printed pattern caused by human error in the prior art, thereby preventing the electronic component from being bonded to the circuit board. Causes a short circuit on the board or a problem of poor connection between the electronic components and the board. In addition, in other embodiments, the platform 11A can also be a fixed flat 2. At this time, the vacuum cleaning mechanism 140 moves the suction nozzle 142 along the first direction by a driving mechanism (not shown), and the *roller cleaning machine (^50 is driven by another driving mechanism (not shown) The cleaning wheel 152 is rolled along the direction y. The driving mechanism is, for example, a suspension drive linear drive pulley, a gear set or a pneumatic/hydraulic controller, which are coupled to the suction nozzle 142 and the cleaning wheel 152, respectively. The shaft 154 is rotated to remove the large-area poor printing pattern from the nozzles 42 and the cleaning wheel 152. In summary, the present invention allows the step of clearing the printed pattern to automatically avoid the artifacts of the prior art (4). The problem of the shed case is not clear. Therefore, the present invention can prevent the electronic component from being bonded to the above-mentioned electric device. The circuit is unique, and the mosquito electronic component and the (four) plate are poorly bonded. The preferred embodiment is disclosed above, but it is not intended to be limiting, and the invention is not limited to the scope of the invention, and may be modified and retouched without departing from the spirit and scope of the invention.
