Abstract:
1. A method of inspecting a printed circuit board comprising the steps of: placing said printed circuit board on a flat uncharged support surface of an adsorption platform; after placing said printed circuit board on said support surface, placing a pressing member on said printed circuit board placed on said support surface such that an entire upper surface of said printed circuit board is pressed by a flat insulating pressing surface of said pressing member while said support surface is uncharged, and while said printed circuit board is not adsorbed on said support surface, wherein said pressing surface of said pressing member is configured to come into contact with the entire upper surface of said printed circuit board; after placing said pressing member on said printed circuit board, adsorbing said printed circuit board on said support surface by an electrostatic force by charging said support surface while said printed circuit board and said pressing member are placed on said support surface; after adsorbing said printed circuit board on said support surface, removing said pressing member placed on said printed circuit board while said support surface is charged; and after removing said pressing member, performing automatic appearance inspection on said printed circuit board adsorbed on said support surface.
