A circuit pattern is quickly created or changed by exposing the circuit pattern on a board without using a photo mask on which the circuit pattern is formed. There is provided a circuit pattern manufacturing apparatus including a forming unit that forms a circuit pattern by irradiating, with a light beam, a circuit pattern forming sheet including an insulating sheet base material layer and a mixture layer made of a mixture containing a conductive material and a photo-curing resin. The forming unit includes, as an optical engine, a housing, a laser diode, a prism mirror, an inclined mirror, a bottom mirror, and a driving mirror.

An object of this invention to perform positioning between the obverse surface and the reverse surface of a sheet and shape a pattern on each of the two surfaces of the sheet. A pattern manufacturing apparatus includes a shaping base, a light beam irradiation window, an optical engine, a lifting head, a head feed mechanism, and a stepping motor. A pattern forming sheet is a sheet in which an admixture containing a conductive material and a photo-curing resin is applied to both of the obverse surface and the reverse surface. The pattern forming sheet is provided with at least one positioning reference hole.

Pattern forming sheet, pattern manufacturing apparatus, and pattern manufacturing method

It is possible to implement pattern formation and pattern manufacturing that eliminate the necessity of high-cost accurate positioning. A pattern manufacturing apparatus () includes a controller () and a laser projector (). The controller () controls the laser projector () to form a pattern on a pattern forming sheet () placed on a stage (). The laser projector () further includes an optical engine (). The optical engine () irradiates the pattern forming sheet () with a light beam (). The stage () has a hollow structure not to obstruct the optical path of the light beam (). The pattern forming sheet () includes a light-transmitting sheet material layer and a photo-curing layer applied to the sheet material layer.
