Problems solved by technology

[0003] The existing liquid medicine addition is divided into two types: one is to manually analyze the sampling components of the liquid medicine at regular intervals, and add the liquid medicine. This method is inefficient and may easily cause intermittent product failure; Analysis, this kind of analysis and control method can only carry out specific gravity analysis on the concentration of electroless nickel plating liquid, but cannot fully analyze the content of each component in the chemical liquid, and the relative control accuracy is low, so it is difficult to ensure the content of each component in the chemical nickel plating liquid , PH value and bath temperature and other parameters are stable

Embodiment Construction

[0015] In order to describe in detail the technical characteristics of the present invention, the achieved purpose and effect, ideal parameter values ​​during normal production: the nickel concentration is 5 ± 0.2g / L, the pH value is 5 ± 0.2g / L, and the temperature is 85 ± 2°C As an example, detailed description will be given in conjunction with the accompanying drawings.

[0016] When performing electroless nickel plating production, use the control input unit 12 in the controller 1 to input parameters: the nickel concentration is 5±0.2g / L, the pH value is 5±0.2g / L, and the temperature is 85±2°C. After parameter input, data analysis unit 13 can record this data, and data analysis unit 13 can gather the temperature value of current chemical nickel plating tank 4 by thermometer 6 simultaneously, gather the pH value of current chemical nickel plating tank 4 by pH meter 3, pass The atomic absorption spectrophotometer 5 collects and analyzes the current content of nickel ions in t...

Description

technical field [0001] The invention relates to an automatic chemical liquid addition system, in particular to an automatic analysis and addition system for electroless nickel plating chemical liquid. Background technique [0002] Compared with electroless nickel plating technology, although the development of electroless nickel plating starts late, the electroless plating layer shows superiority in uniformity, corrosion resistance, hardness, weldability, magnetism, and decoration, and is used by more and more people. applications in various industrial fields. Electroless nickel plating is the most widely used in the electronics and computer industries, involving almost every electroless nickel plating technology and process. Many new electroless nickel plating processes and materials are developed according to the needs of the development of electronics and computer industries. In terms of technical performance, in addition to requiring corrosion and wear resistance, it a...
