Automatic PCB board corrosion chamber

Abstract

The invention discloses an automatic PCB board corrosion chamber. The automatic PCB board corrosion chamber comprises a central control module, a frequency modulation vibration module, a mechanical transmission module, a temperature detection and feedback module, a heating module, a liquid-level sensor module, a stroke control module, an alarm reminding module, an OLED liquid crystal display module, a button module, a drive module and a power supply module. According to the working mode of the automatic PCB board corrosion chamber, the temperature detection and feedback module and the heating module form a closed loop so that the temperature of a corrosion solution is maintained at optimum corrosion temperature range; the PCB board is driven to be vibrated by the vibration of a vibration motor so as to greatly speed up the contact rate of PCB board and effective ions in the corrosion solution; the corrosion solution inside the corrosion chamber is stirred through the gas generated from a gas pump so that the effective ions inside the corrosion chamber are uniformly distributed in the corrosion solution, the corrosion rate is accelerated, the corrosion quality is improved, the erosion waiting time is reduced, the manpower is released through automatic control and the corrosion quality is improved by setting and establishing a delay control mechanism. The automatic PCB board corrosion chamber is simple in operation and is convenient to popularize.

Description

technical field [0001] The invention relates to a PCB circuit board corrosion device, in particular to a fully automatic PCB board corrosion box. Background technique [0002] For companies, enterprise laboratory developers and electronic innovation laboratories of major universities, in the production of circuit boards, mainly through the thermal transfer method, the corrosion of circuit boards is one of the very important procedures. At present, the corrosion of circuit boards in most electronic innovation laboratories in China is still at the stage of manual corrosion. By shaking the corrosion box, the corrosion liquid washes the PCB circuit boards regularly, and then corrodes the PCB circuit boards. A lot of lab developers' time was wasted by manual etching. [0003] Some corrosion devices on the market improve the mechanical structure and shake the corrosion box regularly, so that the corrosion liquid can wash the PCB board regularly. During the shaking process, due ...

AI Technical Summary

Problems solved by technology

During the shaking process, the inertia of the water will maintain the original state, hindering the flow of water, the efficiency is relatively low and a lot of power resources are wasted

[0004] Some corrosion tanks on the market use water pumps to extract corrosive liquid to wash the PCB circuit board in the corrosion tank. Since the internal part of the water pump is in contact with the corrosion liquid for a long time, the water pump is easily damaged, and the PCB circuit board will be corroded by the water pump. Uneven, prone to excessive corrosion in places with high water pressure and insufficient corrosion in places with low water pressure

[0005] Some corrosion chambers on the market use air pumps to generate air bubbles, which agitate the corrosion liquid in the corrosion chamber, thereby speeding up the contact rate between the corrosion liquid and the PCB board, thereby accelerating the corrosion of the PCB board, but this method takes a long time and has low corrosion efficiency
