Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a dispensing machine for PCB board production. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, printed circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin printed circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. Circuit boards can be called printed wiring boards or printed circuit boards. The English names are... FPC circuit boards (FPC circuit boards, also known as flexible circuit boards, are printed circuit boards made of polyimide or polyester films as substrates, with high reliability and excellent flexibility. They have the characteristics of high wiring density, light weight, thin thickness, and good bendability). The birth and development of FPC and PCB have given rise to a new product, the rigid-flex circuit board. Therefore, a rigid-flex circuit board is a circuit board formed by combining a flexible circuit board and a rigid circuit board through processes such as lamination and combining them together according to relevant process requirements, with the characteristics of both FPC and PCB.

[0003] When processing a PCB board, after the PCB board is produced, it will be temporarily stacked beside, and then transported for dispensing. During transportation and stacking, dust in the air will float onto the surface of the PCB board. When dispensing, the glue will be added onto the dust, resulting in insufficient firm connection between the glue and the PCB board, affecting the quality of the PCB board and the dispensing effect.
