Description

Pickling device for PCB production Technical Field The utility model relates to the technical field of PCB production and processing, in particular to a pickling device for PCB production. Background The pickling device for producing the PCB is one of the indispensable devices in the production process of the Printed Circuit Board (PCB), and the PCB is totally called the printed circuit board, also called the printed circuit board, is a supporting body of an electronic component and is a carrier for electric connection of the electronic component. It is called a printed circuit board because it is made using electronic printing. The PCB is an indispensable component in modern electronic equipment, is widely applied to the fields of computers, communication equipment, consumer electronics, automotive electronics, aerospace and the like, and plays a vital role in the pickling process in the production and manufacturing process of the PCB. The method is mainly used for removing oxides, stains and residues on the surface of the PCB so as to ensure the conductivity and the surface quality of the PCB. Since PCBs undergo multiple processes and treatments during production, some oxides, stains and impurities are inevitably left on their surfaces. These residues, if not removed in time, can affect the conductive properties and reliability of the PCB. Therefore, an acid washing process is indispensable. Through searching, a patent document (the authorized publication number is CN 214046195U) is a pickling device for PCB production. The pickling device for PCB production comprises a bottom plate, four supporting rods and a pickling mechanism, wherein the four supporting rods are fixedly arranged on the bottom plate and distributed in a rectangular array, the pickling mechanism is arranged on the bottom plate and comprises a pickling tank, the pickling tank is fixedly arranged on the bottom plate, two first motors are fixedly arranged on one side of the pickling tank, two rotating shafts are arranged in the pickling tank, and the two rotating shafts are both in rotary connection with the pickling tank.
