    • The present invention relates to a method of producing a electrical contact element, in which a multilayer structure is formed by applying a diffusion barrier layer to a base material and at least one metallic layer made of a metal to the diffusion barrier layer, at least one layer formed of tin being applied as the metallic layer. The present invention further relates to an electrical contact element with an electrically conductive base material and a coating which is formed on at least one portion of the electrically conductive base material, the coating having a diffusion barrier layer formed on the base material and the outer layer containing tin. To prevent whisker formation when using the electrical connector element, the present invention proposes, as a solution to the method-related problem, to subject the multilayer structure to a heat treatment such that at least one element of the layer located under the outer layer of the multilayer structure diffuses into said outer layer and the heat-treated outer layer comprises tin. To solve the device-related problem of the invention, it is proposed that the outer layer of the coating be a layer thoroughly alloyed by the diffusion of tin and at least one further metallic element.
    • 本发明涉及一种电接触元件的制造方法,其中通过向扩散阻挡层向基材施加扩散阻挡层和至少一个由金属制成的金属层,形成多层结构,至少一个 由锡作为金属层施加的层。 本发明还涉及一种具有导电基材的电接触元件和形成在导电基材的至少一部分上的涂层,该涂层具有形成在基材和外层上的扩散阻挡层 含锡。 为了防止在使用电连接器元件时形成晶须,本发明提出了作为方法相关问题的解决方案,以使多层结构进行热处理,使得位于下层的层的至少一个元件 多层结构扩散到所述外层中,并且经热处理的外层包含锡。 为了解决本发明的装置相关问题,提出涂层的外层是通过锡和至少一种其它金属元素的扩散而完全合金化的层。
