[0003] The traditional defoaming method is to regularly add defoaming agent to the defoaming device through the pipeline. However, since the defoaming agent is injected from a corner of the defoaming device, the contact between the defoaming agent and the foam is not sufficient, and the foam cannot be eliminated in time. On the one hand, the foam will overflow to the ground, which will affect the production environment of the production line; The amount of artificial addition is not easy to control

The invention discloses a printed wiring board antifoaming agent automatic adding device which comprises an antifoaming groove and a liquid medicine pipeline. A liquid medicine inlet is formed in the antifoaming groove. One end of the liquid medicine pipeline is connected with a container of liquid medicine, and the other end of the liquid medicine pipeline is provided with a water outlet pipe. A plurality of water outlet holes are formed in the outer circumstance of the water outlet pipe. The water outlet pipe is arranged on the liquid medicine inlet. According to the printed wiring board antifoaming agent automatic adding device, a water outlet part of the liquid medicine pipeline is designed into a shape of the water outlet pipe, and the water outlet holes are formed in the water outlet pipe so that antifoaming liquid medicine can enter into the antifoaming groove through the water outlet holes, contact area of the antifoaming liquid medicine and foams in the antifoaming groove is large, and therefore the antifoaming efficiency is high and antifoaming effect is good.
Description
technical field [0001] The invention relates to a device for eliminating foam, in particular to a printed circuit board defoamer automatic adding device which can make the defoamer have a larger range of action and better defoaming effect, and belongs to the technical field of circuit board processing. Background technique [0002] In the production process of the circuit board, the circuit part needs to be filmed, exposed for image transfer, and then produced through the processes of development, etching and film removal; in the film removal section, a large amount of foam will be generated due to the reaction between sodium hydroxide and the dry film , these foams must be discharged in time, so as not to affect the contact and reaction between the sodium hydroxide solution in the film-removing tank and the dry film on the PCB surface, otherwise it will cause the surface of the film to be decontaminated, affect the quality of the PCB board and cause The post-process cannot ...
