4 Thickness of the unalloyed tin coating
4.1 General
This document refers to two different methods to measure the thickness of the tin coating layers on
copper wires, the first one is based on the electrolytic dissolution of the tin layer. The second one is
based on the direct measure of the tin layer on the wires by means of the reflection of an X-ray beam on
its surface.
4.2 Principle of the method based on the electrolytic dissolution of the tin coating
4.2.1 General
Anodic dissolution of a well-defined area of the unalloyed coating using a suitable electrolyte, followed
by detection of the virtually complete dissolution of the unalloyed coating by a rapid change in cell
voltage. Calculation of the unalloyed coating thickness from the quantity of electricity (in coulombs)
used, which can in turn be calculated from:
a) the time interval between the start of the test and the first rapid change of cell voltage, if it is
conducted at constant current density; or
b) the integrated quantity of electricity used in dissolving the unalloyed coating.
4.2.2 Reagents and materials
4.2.2.1 Electrolyte, either a hydrochloric acid electrolyte or an electrolyte recommended by the
instrument manufacturer.
