Description

Lifting immersion type copper precipitation device, circuit board production equipment and system thereof

Technical Field

The utility model relates to an immersion type copper deposition device, in particular to a lifting immersion type copper deposition device, circuit board production equipment and a system thereof.

Background

The current horizontal production line for circuit board hole metallization technology treatment (such as copper deposition, hole metallization) is provided with a horizontal continuous conveying structure, because after horizontal spreading, the circuit board needs to be soaked in liquid medicine for enough time, so that the occupied area of the whole horizontal production line is large. In order to improve the working efficiency, a plurality of stations are needed in some production lines, for example, ultrasonic soaking treatment and other working procedures are adopted, and the occupied area of equipment is further large. Under the condition that the factory rents are more and more expensive, the production cost of a production enterprise can be increased. When used for hole metallization, structures such as a water jet (the treatment fluid is sprayed through a high-pressure spray pipe to penetrate through the holes of a circuit board) high-pressure spray nozzle and the like are added to improve the speed and effect of metallization. Because the horizontal production line continuously and synchronously moves, the time for soaking the circuit board in the treatment liquid cannot be increased by adding auxiliary devices such as a water knife, ultrasonic waves and the like. The soaking time of the circuit board in the treatment liquid is increased, so that the treatment effect and the working efficiency are effectively improved. The existing structure is then flat-laid, requiring an increase in soak time, with only two methods, one to reduce the horizontal transfer speed and the other to increase the length of the horizontal line. Both of these methods increase the production costs of the manufacturing enterprises for a long period of time.

Therefore, there is a need to develop a small footprint production arrangement that can be used for immersion production of board-like workpieces such as circuit boards.
