Abstract

The invention relates to a PCB (Printed Circuit Board) lift etching machine and a using method thereof. The lift etching machine comprises a base, wherein an etching tank, a bubble generator and a heating temperature control device are arranged on the base; the bubble generator is communicated with the etching tank through an air pipe; an upper cover is arranged on the etching tank, a lifting device is arranged above the upper cover, and a vibration device is arranged on the upper cover; the lifting device comprises a top plate, a lift control box and a transmission device; a supporting column is arranged on the base and is used for supporting the top plate; the transmission device comprises a lifting motor, a driving gear, a transmission gear, an output gear, a guide rod and a screw rod; the upper end of the screw rod penetrates through the lower end of the top plate and the upper cover, and the lower end of the screw rod is connected with the upper cover in a threaded manner; the upper end of the guide rod is fixed on the lower surface of the top plate, and the lower end of the guide rod runs through a guide sleeve; the guide sleeve is arranged on the upper cover in a penetrating manner; the driving gear is arranged on the output shaft of the lifting motor; the output gear is arranged at the upper end of the screw rod; and the transmission gear is in meshed transmission with the driving gear and the output gear. The PCB lift etching machine has the advantages of simple structure, convenience in operation and popularization and high etching efficiency.

Description

technical field [0001] The invention relates to a pcb board lifting corrosion machine and a using method. Background technique [0002] With the development of society, smart electronic products are widely used in life, and pcb circuit boards are also widely used in smart electronic products. However, many enterprises and their developers, as well as electronic innovation laboratories in colleges and universities, mainly produce circuit boards by thermal transfer printing. In this process, the corrosion of circuit boards is one of the most important procedures. The corrosion of circuit boards in many innovative laboratories is still at the stage of manual corrosion, that is, by shaking the corrosion box to make the corrosion solution wash away the PCB circuit board, thereby accelerating the corrosion of the PCB circuit board. However, manual etching will waste a lot of time for laboratory developers, greatly reduce work efficiency, and virtually increase the cost of the ent...

However, manual etching will waste a lot of time for laboratory developers, greatly reduce work efficiency, and virtually increase the cost of the enterprise.

[0003] Some corrosion chambers on the market today use air pumps to generate air bubbles, which stir the corrosion liquid in the corrosion chamber to speed up the contact rate between the corrosion liquid and the surface of the PCB board. At the same time, the temperature of the corrosion liquid is heated by the heating rod, and the two promote each other. This will speed up the corrosion of the PCB board, but this method still takes a long time to corrode
