The surface of the article is cleaned as pre-plating basis metal, pre- and post-coating treatment is given to reduce the risk of hydrogen embrittlement.
Dewetting is a condition that results when molten solder coats a surface and then recedes, leaving irregularly shaped mound(s) of solder separated by areas that are recovered with a thin film of solder and with the basis metal unexposed.
* In the case of the 42MoCr11 steel, analysing the combination layer microstructure it was noticed the emersion of the continuous combination layer with limit of separation towards the basis metal. The depth of this layer varies between 1 [micro]m (1h / 450 [degrees]C) and 12 [micro]m (16h / 550 [degrees]C); the metal structure remained unchanged, with globular carbides.
The IPC-T-50 Terms and Definitions document defines solder wetting as "the formation of a relatively uniform, smooth, unbroken and adherent film of solder to a basis metal."
