Problems solved by technology
[0002] As the size of electronic products shrinks, the thickness becomes thinner, miniaturized, and integrated; printed circuit boards must have more dense wires and thinner boards; circuit board lines gradually change from conventional 50um to 40um, 30um The direction of development, the thickness of the circuit board gradually develops from 0.05mm to 0.03mm; as the circuit becomes smaller and more dense, the traditional developing or etching machine can no longer meet the development of the direction of smaller, denser and thinner , can only satisfy 40um small lines, and has reached a bottleneck period; the main performance is the pool effect on the circuit board
Conventional swing development or etching cannot eliminate the pool effect on the upper surface, which leads to different reaction rates at the edge and the middle, and cannot be developed and etched to finer lines

The invention discloses a high-efficiency circuit board production system, which comprises a circuit board conveyor line, a liquid medicine container, a spray system and water absorption knifes. The circuit board conveyor line is arranged above the liquid medicine container; the spray system sprays in the direction of the circuit board conveyor line; and the water absorption knifes are arranged above the circuit board conveyor line. The system also comprises vacuum generators and fans. An air outlet of each fan is communicated with a compressed air inlet of the corresponding vacuum generator, and an adsorption chamber inlet of each vacuum generator is communicated with an absorption through hole of the corresponding water absorption knife. The system adopts wind to drive the vacuum generators to generate negative pressure for the water absorption knifes, so that the system is simple and reliable in structure; and through a "one-to-one" mode, one vacuum generator provides suction force for one water absorption knife separately, thereby avoiding a conventional gas internal circulation method, reducing requirements for and corrosion to the fans, reducing cost and improving production efficiency.
