    Abstract: A method for mounting a component (100) on a workpiece (106), the method comprising obtaining information regarding a surface topography of at least one of a mounting surface (102) of the component and a local surface (108) of the workpiece onto which the component is to be mounted. The method further comprises forming a plurality of deposits (110) of a viscous medium on at least one of the mounting and local surfaces, wherein each of the plurality of deposits has a height (/½, /½, h3) based on the obtained information, and is formed by individually applying at least one droplet (234) of the viscous medium (232) using non-contact dispensing. The method further comprises placing the component on the substrate, such that the plurality of deposits of viscous medium forms a connection between the component and the workpiece.

    Abstract: An object of the invention is to provide a printed wiring board which is less likely to cause foaming even after a reflow step and in which a metal reinforcing plate is less likely to be peeled off, a manufacturing method thereof, and an electronic device. A printed wiring board (1) according to the present invention includes a wiring circuit board (6), a conductive adhesive layer (3), and a metal reinforcing plate (2). The conductive adhesive layer (3) is bonded to each of the wiring circuit board (6) and the metal reinforcing plate (2). The metal reinforcing plate (2) includes a nickel layer (2b) formed on a surface of a metal plate (2a). A ratio of a surface area of nickel hydroxide to nickel present in a surface of the nickel layer (2b) is more than 3 and equal to or less than 20.
