Official abstract text for this publication.
A semi-automatic corrosion box of a copper clad laminate is disclosed. The corrosion device comprises a box body which has no cover; a baffle plate which divides the corrosion box into an upper part and a lower part, wherein a copper clad laminate circuit board is placed on the baffle plate, and a temperature detection module, water pumps and a heating rod are placed on a lower part; and a thermal imaging camera which is placed on a pressing plate through a bracket. Modules in corrosive liquid are connected with an external single chip microcomputer control module through corrosion-resistant wires. The working mode of the present invention is that time and temperature are set with a key matrix at first, and the control module can automatically stop working and enter a low power consumption mode.

The invention claimed is: 1. A semi-automatic corrosion device of a copper clad laminate, comprising a corrosion box, a water pump flushing part, a heating part, a temperature display part, a control part and a processing part, wherein the corrosion box comprises a box body, a baffle plate and a pressing plate; the box body is divided by the baffle plate into an upper part and a lower part; and the lower part has a small volume for storing a heating rod, a temperature detection module and corrosive liquid; a copper clad laminate is placed on the baffle plate; one end of the baffle plate is a protruding one-piece uncovered rectangular container, and is connected with three water pumps; the water pumps face upwards, and the function of uniformly flushing the copper clad laminate with the corrosive liquid is realized by control; a flushing part is defined by the lower part of the corrosion box, the water pumps and the upper part of the corrosion box; and the pressing plate is located above the uncovered rectangular container, and can be folded on the corrosion box to prevent the corrosive liquid from being sprayed out of the corrosion box; the water pump flushing part is divided into three relays and three water pumps; the three relays are placed outside the corrosion box, and is connected with the three water pumps at the lower part of the corrosion box through lines to achieve uniform flushing of the corrosive liquid, and the corrosive liquid covers the copper clad laminate to a certain height; the heating part is a DC 24V, 100 w etch-resistant heating rod; the heating rod is placed on the lower part of the corrosion box; and the activity of the heated corrosive liquid is increased, and the corrosion efficiency is greatly increased; the temperature display part is mainly composed of an ink screen, a thermal imaging camera and a waterproof temperature sensor; the ink screen and a processor of the processing part are placed together; the waterproof temperature sensor is placed below the corrosion box, and connected with the processor through a corrosion-resistant wire; the thermal imaging camera is placed on the pressing plate; the temperature is detected by the non-contact thermal imaging camera and the contact temperature sensor; the processor provides a temperature signal to the ink screen; and the temperature display is used to confirm whether the temperature is increased to a set value, and control the heating part; the control part is mainly composed of a key matrix and a display ink screen; and the display screen displays the content, and keys are used to select states to realize the function of controlling the temperature and the heating time; the processing part is composed of the processor, an LED display, a buzzer and a corresponding bottom plate; the bottom plate provides sockets for the processor, the ink screen and the relays for convenient control; the processing part is placed outside the corrosion box and controls the water pump flushing part, the heating part, the temperature display part, the control part; the LED and the buzzer are used for indicating corrosion states.
