Description

Technical Field

[0001] The utility model relates to the technical field of spray swing racks, in particular to a PCB board spray swing rack. Background Art

[0002] During PCB production, the PCB boards need to be sprayed by spraying equipment. The main functions of spraying PCB boards are as follows:

[0003] 1. Cleaning function: remove dust, oil, oxide and other pollutants on the surface of PCB board to make the board clean and prepare for subsequent processing or use.

[0004] 2. Etching: Under the spraying of specific etching liquid, the unnecessary copper foil part can be etched away to form the required circuit pattern.

[0005] In PCB spray equipment, the swing frame is the core component of the spray. It is used to mount and fix nozzles to spray liquid. At the same time, the swing frame can also swing back and forth through the equipment's connecting rod swing mechanism to ensure that the spray liquid can fully contact the PCB board. However, current spray swing frames mostly adopt a single-channel structure, with multiple nozzles supplied with liquid through the same liquid pipe. When this structure is in use, due to the different distances between each nozzle and the water source, it is easy to cause the water flow sprayed from the nozzle to be uneven, thus affecting the spraying effect.

[0006] Therefore, those skilled in the art provide a PCB board spray swing rack to solve the problems raised in the above background technology. Utility Model Content
