TECHNICAL FIELD

[0001] The present application relates to the technical field of PCB copper plating mother basket, and particularly to a mother basket with an inclined loading structure. BACKGROUND

[0002] In the PTH (chemical copper plating) process of PCB (printed circuit board), especially when a gantry production line is used, the PCB to be processed, such as an inner layer board, needs to be loaded into a special mother basket (also known as a hanging basket or carrier), and the mother basket is moved by a lifting device on the production line to sequentially pass through various chemical liquid tanks for cleaning, micro-etching, activation, copper plating and other processing procedures. The mother basket is a key carrier connecting the automatic transmission system of the production line and the PCB, and its performance directly affects the efficiency, stability of production and the quality of the PCB.

[0003] At present, when the mother basket is used for loading in the PCB copper plating process, the frame in the mother basket is in a 90-degree vertical state with the mother basket, which makes it difficult to discharge the air bubbles in the small holes during copper plating production, and easily causes the copper defect in the holes, affecting the product quality. In addition, although the current PCB copper plating mother basket is equipped with an adjustable limiting structure for limiting the printed circuit boards of different widths, the adjustment relies on bolt fixing, and multiple bolts need to be screwed, which makes the limiting structure adjustment process more complicated and not convenient to operate.
