Description

Circuit board water-soluble film pressing water supply device Technical Field The application relates to the technical field of circuit board film pressing, in particular to a water supply device for a water-soluble film pressing of a circuit board. Background The circuit is more and more dense, interval, pad are smaller and smaller, therefore need to realize with the multilayer circuit, and the multiple electroplating/multiple pressfitting is needed when the multilayer circuit, the more complicated the flow, the greater the probability of forming the dent/scratch of the face, its dent of face, scratch dent etc. directly influence the quality yield of circuit board open circuit/breach etc. in the circuit figure transfer process, the press film as important step, traditional press film method is unsettled in the dent/scratch position easily, forms open circuit, breach when leading to the later process etching, the present wet film pasting technology is unstable because of supplying water. The current water-soluble film pressing water supply device is, and the commercial water directly supplies the mode, receives other equipment water consumption and front end water supply pressure to influence, and the fluctuation is very big, if supply water is too little, causes to scribble the water yield not enough, can not reach the filling effect with the replacement of dry film, if supply water is too big, the water yield increases, influences the film pressing effect, and unnecessary water is likely to overflow to equipment simultaneously, causes the damage of equipment, can also further make the improvement. In order to solve the problems, the application provides a water-soluble film-pressing water supply device for a circuit board. Disclosure of utility model The application provides a water-soluble film-pressing water supply device for a circuit board, which adopts the following technical scheme: The utility model provides a circuit board water-solubility press mold water supply installation, includes supply tank and pump box, supply tank one end fixed mounting has the pump box, and pump box internally mounted has the constant pressure water pump to constant pressure water pump input is through the bottom link up with the supply tank in through the drinking-water pipe, constant pressure water pump output link up and is connected with the outlet pipe, and the outlet pipe other end link up and be connected with the shunt tubes to the shunt tubes other end link up and be connected with the quick-operation joint, the supply tank other end link up and be connected with the inlet tube, and inlet tube surface mounting has the solenoid valve to supply tank internally mounted has liquid level switch.
