Description

Foolproof method for MTO of gold cylinder

Technical Field

The invention relates to the technical field of PCB processing, in particular to a gold cylinder MTO foolproof method.

Background

The chemical concentration is basically analyzed at the current stage of the surface treatment to determine whether the chemical needs to be added. On-line liquid medicine analysis is synchronously introduced, a concentration range is set, and liquid medicine is automatically added according to the concentration ratio beyond the limit. For example: controlling (4.6-5.2) g/L of nickel ion concentration in the nickel tank; the control value of the analysis content of the actual liquid medicine is influenced by various elements, and only the concentration of the liquid medicine is simply analyzed to be inaccurate. The automatic adding of the liquid medicine at the present stage only increases the frequency of the concentration of the liquid medicine to be tested, for example, the manual sampling analysis is adopted before, and is generally defined as once per shift, the automatic adding at the present stage can automatically analyze the fixed important parameter concentration of the liquid medicine once per hour, and then the liquid medicine is automatically added according to the concentration. The amount is automatically added based on the original concentration conversion volume of the liquid medicine. The pollution of impurities to liquid medicine caused by the internal and external environments in the actual production process and the board production process cannot be considered, and the quality of products can be influenced synchronously. Therefore, the time when the immersion gold surface needs to be replaced to treat the medicine water tank is always not determined, and factors of the influence of external influence are relatively large, for example: the density of product production, the area of the surface of the product to be deposited with gold, centralized production, etc. The situation that the tank liquor is polluted and is not suitable for production and production continues to be carried out, so that bad plates are produced, the plates are produced in the output stage, the batchability is abnormal, and then a wire body is removed for inspection, so that cylinder replacement is possibly needed.
