AI Technical Summary

Technical Problem

Existing testing methods cannot meet the electroplating performance testing requirements of a 500mL Hull bath. The lack of unified testing standards and evaluation systems results in time-consuming and material-intensive testing processes, which cannot meet the needs of actual production applications.

Method used

A method for testing and evaluating electroplating performance based on a 500mL Hull cell is provided. By locating near-focal point B, high point H, low point L, and far-deep point D on the cathode sample, the coating thickness is measured and the dispersion ratio T is calculated. Combined with the movement l of the cathode sample, multiple indicators can be tested simultaneously.

Benefits of technology

Quantitative analysis in a 500mL Hull cell was achieved, improving testing efficiency and accuracy. It can obtain multi-dimensional performance indicators such as dispersion ability, high and low zone deposition rate, deep plating ability and appearance quality in a single test, solving the problem of insufficient sample volume in traditional methods and has broad application prospects.

Abstract

This invention relates to the field of electroplating performance evaluation technology, and particularly to a method for testing and evaluating electroplating performance based on a 500mL Hull bath. The steps are as follows: S1, Pour the electroplating solution to be tested into a 500mL Hull bath, place the anode and cathode test pieces, and maintain the temperature of the plating solution at a set temperature; S2, Apply a direct current and electroplat for a set time at a set current magnitude; S3, After electroplating, remove the cathode test piece, clean and dry it, and then sequentially locate the near-focal point B, high point H, low point L, and far-depth point D on the central axis of the cathode test piece. Measure the coating thickness and record it as δ. B δ H δ L and δ D Simultaneously, record the farthest distance from the near end of the cathode sample to obtain a qualified bright coating, as the travel distance l; S4, calculate the dispersion ratio T based on the measured data. The electroplating performance testing and evaluation method provided by this invention can obtain multiple key performance indicators at once, is suitable for the rapid screening and evaluation of scarce intermediates, and has good application value.
