Abstract
The invention discloses a minitype fast corrosion tank of a printed circuit board (PCB), comprising a rectangular box made of transparent materials, wherein a first side of the box is externally provided with a control box; the control box is internally provided with a temperature sensor, a control circuit board and an air pump; the temperature sensor is tightly adhered to the first side of the box and is electrically connected with the control circuit board; a second side of the box is internally provided with a liquid level sensor and a vertical glass heating pipe; the lower end of the glass heating pipe is sealed, and the power line of the glass heating pipe is lead out from the upper end of the glass heating pipe and is connected to the control circuit panel; the liquid level sensor is electrically connected with the control circuit board; an elastic micropore rubber tube is arranged above the baseplate of the box; the two ends of a transparent air tube are respectively connected to the elastic micropore rubber tube and the air pump; a plurality of cover fillets are arranged above the box, and the two ends of each cover fillet are respectively provided with a groove which is matched with the box; and the cover fillets are provided with a plurality of third through holes. The corrosion tank provided by the invention has the advantage that air flow is adopted to disturb a corrosive liquid in the box, thus the corrosion speed of the PCB is quickened.
Description
Technical field
The present invention relates to corrosion device, relate in particular to a kind of small-sized PCB and corrode the pond fast.
Background technology
In recent years, a lot of electrical type Creative Labs have been created by domestic each colleges and universities, in the corrosion link of PCB; Quite a few all still adopts manual caustic solution; Promptly be placed on the copper clad plate of the good line of cloth in the container that corrosive liquid is housed, manually rock copper clad plate then, to accelerate corrosion rate.
Existing a kind of small-sized etching apparatus, its casing are divided into two parts up and down, adopt a little water pump that corrosive liquid is being circulated in two parts up and down.But this small-sized etching apparatus exists water pump fragile, and corrosion rate waits defective slowly.
Summary of the invention
The present invention is directed to the deficiency of prior art, provide a kind of small-sized PCB to corrode the pond fast.
Technical scheme of the present invention is following:
A kind of small-sized PCB corrodes the pond fast, it is characterized in that comprising the rectangular casing of processing with transparent material, and the floor below of casing is provided with four rubber mats; The outside, first side of casing is provided with control cabinet, is provided with temperature inductor, control circuit board and air pump in the control cabinet, and temperature inductor is close to first side of casing; Temperature inductor is electrically connected with control circuit board, and the inboard of first side and the outside are equipped with several convexities, is provided with first through hole of up/down perforation in the convexity; Also be provided with second through hole on first side, the height of second through hole is greater than all protruding height, and the inboard of second side of casing is provided with level sensor and vertical glass heats pipe; The lower end of glass heats pipe is sealed, and control circuit board drawn and be connected to by its power line from the upper end, and level sensor also is electrically connected to control circuit board; The top of the base plate of casing is provided with elasticity micropore sebific duct; Transparent tracheae passes first through hole and second through hole successively, and the two ends of transparent tracheae are connected to elasticity micropore sebific duct and air pump respectively, and the top of casing is provided with several cover fillets; The two ends of cover fillet are provided with the groove that cooperates with casing, and cover fillet is provided with some third through-holes.
Compared with prior art, the present invention has following advantage:
(1) the present invention adopts the corrosive liquid in the flow perturbation casing, blows out bubble disturbance corrosive liquid by the numerous micropores in the elasticity micropore sebific duct, accelerates the corrosion rate of PCB;
(2) air pump does not contact with corrosive liquid, and is therefore more reliable than water pump in the corrosive liquid, not fragile;
(3) the present invention adopts corrosion resistant glass heats pipe heating corrosive liquid, can accelerate the PCB corrosion rate, the glass heats pipe lower end closed of vertically placing, and integrally formed with glass, there is not problem in the dead of night;
(4) temperature inductor of the present invention is attached to the side of casing, and control circuit board is according to the operating state of the temperature signal control glass heats pipe of temperature inductor, and the temperature maintenance that makes corrosive liquid is about 60 ℃;
(5) among the present invention, when corrosive liquid was lower than a certain boundary, the existence of level sensor can make control circuit board report to the police automatically.
