Plating failure: new plating application and plating failure

<

With the development of electroplating clean production, when researching and developing new electroplating processes, people must gradually carry out small test, pilot test, production line assessment from the results of the laboratory, and finally carry out mass production. In these processes, the experience of plating troubleshooting can be gradually accumulated. Because such a plating failure in mass production is inevitable, but the probability of failure is less, the technicians can handle it because of the previous experience, which is relatively easy.

For a new plating process or a new plating solution, is it often said that the new process and plating solution are stable? Obviously unstable plating solution is very easy to fail, and it is impossible to carry out normal plating processing parts. As a technician who develops this new plating process, it is necessary to put the stability of the new plating solution developed (the skin is good) and the stability of the plating process conditions (temperature, current density, pH, etc.) to be the first place.

This requires the researcher to record in detail in the laboratory or in the small test process the various faults that occurred during the test and the adjustment methods for the fault. Even if the small test and the pilot test are very successful, there may be such a failure problem in the big test or trial production process. Because in the laboratory and small test process, the consumption change of the plating liquid component is very different from the actual large groove, the geometric difference between the test piece and the actual part will lead to the failure problem that does not occur in the small test. Therefore, the details It is very important to record and analyze the failure phenomena in the pilot and production line assessment process.

In fact, the new electroplating process has passed the production test for a certain period of time, and has met the requirements of industrial production. In the subsequent production process, such failures may occur due to the imbalance of solution components, the accumulation of impurities, new matrix materials, etc. Therefore, the researchers of the new electroplating process should keep track of the use of new processes, keep recording and accumulating information in this area, and lay a solid foundation for the technical services of the new formulation of electroplating new processes.

For electroplating processes that have been used for many years, electroplating failures require electroplating technicians to find out the cause of electroplating failures as soon as possible. "The right medicine" cures the problem of electroplating failure, otherwise it will affect electroplating production. Some electroplating technicians, especially those with many years of work experience, know how to analyze plating failures and troubleshooting methods, can quickly find out the cause of failure in electroplating production, and then "prescribe the right medicine" to promptly eliminate the failure in electroplating production. . However, there are also some technicians who have no production experience and do not understand the method of analyzing plating faults. It is difficult to quickly find out the cause of the plating failure. Under the pressure of normal production, blindly handling the fault, it may be that the fault is not removed, but instead Production has a greater impact. Sometimes the technicians sent by the electroplating syrup supplier do not understand the faults before and after the scene, and it is difficult to quickly eliminate the faults. Therefore, technicians who develop and research new formulas for electroplating new technologies should frequently track and accumulate plating faults. The phenomenon, the analysis of the cause of the failure, the troubleshooting method, etc., to accumulate the experience of on-site troubleshooting for the normal use of new users and less failure.
