Abstract: A non-contact, step-wise method for automatically positioning a sensing probe, having a vibrating cantilever and tip, above a target surface utilizing acoustic and Van der Waals interactions respectively during an approach method. The sensing probe is lowered to a substantially optimized tip to target surface distance. The system utilizes the interaction of forces between the vibrating cantilever and target surface to automatically position the sensing probe above the target surface.

Abstract: A method of tinning tinnable areas of an electronic component package, the method comprising a first step during which additional metal is applied in the liquid state to said tinnable areas, and a following step during which at least one cycle of oscillations about an equilibrium position is applied to the package while said metal thus applied is still in the liquid state, for the purpose of setting up successive and opposite displacements of masses of said metal along said areas in order to obtain a uniform distribution of said metal over said areas.
