WebAccording to the IPC standard, non-wetting is defined as the inability of molten solder to form a metallic bond with the base metal. This results in the PCB pads or the component’s terminals not catching the solder during the reflow process. Dewetting is a condition that results when molten solder coats a surface and then recedes leaving ...

WebMar 17, 2024 · Eq. 1 underlies an elementary description of delamination as a generalization of the standard dewetting transition (which occurs as Γ → 0 + ), to “curvature-induced dewetting” (which occurs as Γ* → 0 + ). In this generalization, the sheet’s elastic energy is simply viewed as an addition to the sheet–substrate adhesion energy.
