Problems solved by technology

However, the test of additives for deep plating ability is currently judged by the bright position of the additive, and the test verification is also carried out with test pieces, which cannot meet the deep plating ability verification of through holes.
Multiple test strip tests have verified that its positioning is good, but the effect of deep-plated samples is not good

Abstract

The invention discloses a test device for deep plating capacity of through holes, which comprises a cathode conductive rod (1), the two ends of the cathode conductive rod (1) are connected to a conductive hook (2), and the bottom of the conductive hook (2) is connected to a wire (3). . The use of the device for testing speeds up the matching between the test and the actual production, and improves the ability to transform the test results into production and application.

Description

technical field [0001] The invention relates to a test device and a test method for deep plating ability of through holes, in particular to a test device and test method for deep plating ability of through holes with good effect of deep plating samples. Background technique [0002] The electroplating industry often encounters the electroplating of workpieces with long through holes. Generally, electroless nickel plating is used for apertures smaller than Ф6×30. However, with the strict implementation of environmental protection requirements, the wastewater treatment of electroless nickel plating solution has become a bottleneck in the production of enterprises. Enterprises urgently need electroplating nickel instead of electroless nickel plating under the condition of quality assurance. First, the wastewater treatment is solved, and second, the cost is greatly reduced. With the Hull cell test of the test piece, all the additives that increase the deep plating ability meet t...
