A method for depositing a material to join two surfaces of an electronic assembly includes determining, using dimensions of a pad area of a substrate, a deposition pattern for the material that extends across the pad area of the substrate. The method further includes creating a tool to deposit the material in the deposition pattern that extends across the pad area of the substrate.

Drawing device for drawing a tool (T), comprising: a support (2), provided with rests (21), structured to be slidably arranged in contact with an inner wall of a tube, and an attachment (22) for a tool (T); a cursor (3), movable along a longitudinal direction (Y) between at least a starting position and a return position; magnetic means (4), predisposed to magnetically constrain the support (2) and the cursor (3) with respect to the displacement along the longitudinal direction (Y).

A manufacturing method for a plate comprising channels in which the method includes a step of superposing the two strips, a step of welding the two strips along the weld seams, a step of blocking the zones between the weld seams on one side of the strips, a pressurization step with a compressed fluid, where the zones between the weld seams open out along another side, to expand the strips, and a step of opening the zones blocked during the blocking step. This manufacturing method enables the titanium strips to be welded together and shaped by pressurization.

An electromagnetic apparatus for active intervention to a shape of a molten pool is provided. In the present invention, a workpiece is placed on stepped surfaces of a test bench. Upon power on, a metal rod rotates to generate a toroidal magnetic field centered on the metal rod, and the toroidal magnetic field acts on the molten pool to generate an induced current. The induced current generates Lorentz force under the action of the magnetic field, which acts perpendicularly on an outer surface of the molten pool, thereby changing the height, depth and width of the molten pool, and finally realizing the active intervention to the molten pool shape.
