Chemical tin plating thickness measurementinstrumentUtilize continuous voltage electricityFlow,The tin plating layer on the sample test piece can be electrolyzed shellget rid of.When the pure tin layer is completely removedafter，The voltage and current required to remove the copper tin alloy layer, It will suddenly Greater than the removal value of pure tin layer. This value suddenly changes,Can make this machine sense and stop the electrolysis action,And automatically calculate the thickness.Pure? The removal time of the layer will be proportional to the thickness of pure tin. The machine screen will display The thickness of the pure tin layer can be selected in units of thickness,One millionth of a meter microns Or one millionth of an English?micro inches.
