Problems solved by technology

[0005] After the ceramic plate is copper-plated, during the pull-off bonding force test, the ceramic is often broken before the film is pulled off due to the fragile characteristics of the ceramic, and the ceramic copper-plated plate is tested by traditional methods such as exposure, development, and etching. The method of copper-plating squares on ceramic plates is time-consuming and labor-intensive. In addition, the existing detection methods can only qualitatively or semi-qualitatively measure the bonding force of the coating, but cannot quantitatively measure the bonding force between the substrate and the coating. Therefore, it is necessary to explore a method that can both qualitatively and quantitatively detect the bonding force of the ceramic copper-clad plate coating.

Embodiment 1

[0027]The method for testing the adhesion pull-off of the ceramic plate described in Example 1 consists of the following steps:

[0028](1) Cut squares of a certain size on the ceramic copper-plated plate, and ensure that each cut square can be cut to the ceramic substrate to obtain a ceramic copper-plated plate test sample;

[0029](2) Brush the copper layer on the other side of the ceramic copper-plated test sample with solder paste, and then press the entire surface of the ceramic copper-plated test sample with the copper foil;

[0030](3) Heat the pressed ceramic copper-plated plate test sample and copper foil at a constant temperature of 240°C. After the solder paste is melted, take the pressed ceramic copper-plated plate test sample and copper foil to lower the temperature. The ceramic copper-plated plate test sample and the copper foil are completely bonded together to prepare test sample A;
