Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production devices, in particular to a circuit board immersion gold device. Background Art

[0002] Immersion gold is a method of depositing a gold layer of chemical nickel-gold by chemical oxidation-reduction. It can achieve a thicker gold layer. As the integration of electronic products becomes higher and higher, the pins are becoming more and more dense. The traditional gold plating method can no longer meet the needs of circuit board production, and the surface immersion gold technology has solved the problems that gold plating cannot solve. However, the existing immersion gold device usually immerses the circuit board into the immersion gold solution, and increases the reaction rate between the circuit board and the solution by vibrating the circuit board in the solution tank.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN215420991U discloses a surface gold deposition device for circuit board production, which uses a bracket to fix the circuit board to be surface gold deposited, and then, by connecting a vibrating part to the bracket, the vibrating part generates vibration, so that the bracket vibrates, and then the circuit board on the bracket vibrates in the medicine in the medicine tank, thereby increasing the reaction rate between the circuit board and the medicine, thereby improving the gold deposition efficiency, and by providing a circulating filter part, the solid particle debris in the medicine tank is filtered and removed by the circulating filter part, so as to avoid the solid debris affecting the gold deposition of the circuit board and ensure the quality of the gold deposition of the circuit board.

[0005] However, the above patent still has some problems that need to be improved during actual use. The most obvious one is that when cleaning the solid particles in the filter, the filter needs to be removed from the filter tank. At this time, the filter cannot continue to filter the medicine, and the filtering of the medicine needs to be stopped, which affects the filtering efficiency of the medicine.

[0006] To this end, we proposed a circuit board immersion gold device to solve the above-mentioned drawbacks. Utility Model Content
