Abstract
The utility model relates to an etching machine, in particular to a spraying type etching machine for making a printed circuit board. The spraying type etching machine comprises an etching cylinder, wherein microwave heating tubes made of gallium nitride are arranged in the etching cylinder; magnetrons and waveguides are arranged in the heating tubes; a control box is arranged above the etching cylinder; a high-voltage transformer and a protection component are arranged in the control box; and a microwave heating device consists of the high-voltage transformer, the protection component, the magnetrons and the waveguides. A microwave heating mode is adopted, so that the heating speed is high, and heating is uniform; a chemical group is activated, so that the etching speed is increased, the yield is increased, and the production efficiency is improved; the etching rate is up to 71Hz; and the yield is more than 5,500 m<2>/d. The whole etching machine is shortened (namely an etching section is shortened), so that the etching machine is developed towards minimization direction as much as possible; the standby time is shortened, so that energy is saved; and by adopting the pumping mode of the conventional air pump, the problem that a nozzle is plugged because the Cu<+> content in etching liquid is overhigh, the reaction speed is extremely low, and the Cu<+> cannot be dissolved in the etching liquid is solved.
Description
Technical field
The utility model relates to a kind of etching machine, specifically relates to a kind of spray-type etching machine for preparing printed circuit board.
Background technology
Existing spray-type etching machine all is direct-fired with the titanium steel electric heating tube, and etching section speed is 30～40Hz, production capacity 3000m
2About/sky, and striping section speed can cause etching section speed and striping section speed not to match very much up to 80 Hz, is restricting the production capacity of etching machine.
Summary of the invention
Therefore, the purpose of the utility model be to provide a kind of can significantly improve etching section speed, improve the spray-type etching machine of the preparation printed circuit board of production capacity greatly.
The purpose of the utility model is to realize like this.
A kind of spray-type etching machine for preparing printed circuit board; Comprise the etching cylinder; Be provided with nitrogenize in the said etching cylinder and transfer the microwave heating pipe of material, be provided with magnetron and wave guide in the heating tube, said etching cylinder top is provided with controlling box; Be provided with high-tension transformer, Arming Assembly in the controlling box, high-tension transformer, Arming Assembly, magnetron and wave guide constitute microwave heating installation.
Said controlling box housing is provided with radiator fan.
Adopt microwave heating, rate of heating is fast, is heated evenly; The activation group is accelerated etching speed, increases production capacity, enhances productivity, and etch-rate can reach 71 Hz, production capacity 5500m now
2/ d is above.Shorten complete machine length (length that refers to the etching section), develop to miniaturization as far as possible.Shorten standby time, save energy.Cooperate traditional air pump to inflate mode, solved Cu in the etching solution
+Too high levels reacted slow, Cu
+Be insoluble to etching solution and cause the difficult problem of plug nozzle.
Description of drawings
Accompanying drawing is the partial schematic diagram of etching machine, mainly reflects etching cylinder improvement part.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
A kind of spray-type etching machine for preparing printed circuit board; Comprise etching cylinder 1, be provided with the microwave heating pipe 2 that material is transferred in nitrogenize in the said etching cylinder 1, be provided with magnetron and wave guide in the heating tube 2; Said etching cylinder 1 top is provided with controlling box 3; Be provided with high-tension transformer, Arming Assembly and other accessory (because these all belong to prior art, no longer tired stating executed in this practicality) in the controlling box 3, high-tension transformer, Arming Assembly, magnetron and wave guide constitute microwave heating installation.Said controlling box 3 housings are provided with radiator fan.
