PURPOSE: An apparatus for inspecting coating quality of an electronic part and a solder is provided to rapidly and precisely carry out an inspection process by generating a Moire pattern using a prismatic beam splitter. CONSTITUTION: An apparatus for inspecting coating quality of an electronic part and a solder includes at least one light source(10), at least one diffuser(20) for evenly diffusing light radiated from the light source(10) and at least one fixing lattice(30) for generating a lattice pattern. A beam splitter(40) is provided to allow light passing through the fixing lattice(30) to be projected on an object(1). A collimating lens(50) is provided to collect light passing through the beam splitter(40). A projection lens(60) is provided to form a Moire pattern of the object(1). The Moire pattern is converted into an image by a CCD camera(80). A signal processing section(90) makes 3-dimensional image information by processing an image signal of a control section(70).
