Abstract: The invention relates to a device for generating a plurality of laser beams. The device comprises: a laser source emitting an initial beam at P wavelengths; a wavelength splitter assembly for splitting the initial beam into N intermediate beams where N≦P, each intermediate beam containing a group of wavelengths comprising at least one wavelength; and N′ energy splitter assemblies where N′≦N for splitting an intermediate beam into ni divisional beams, each of the ni divisional beams having substantially the same energy, whereby K divisional beams are obtained with K = N - N ′ + ∑ i = 1 i = N ′ ⁢ n i .

Abstract: The invention relates to a punch machine for punching a panel in which the position of each hole to be made is identified by a mark. The machine comprises a structure for receiving said panel, said structure presenting X and Y directions; means for holding said panel relative to the structure; at least four punch blocks secured to a support, each punch block having at least one punch carrier tool and at least one matrix carrier assembly; means for displacing each punch block separately in the X and Y directions and in rotation; optical means for comparing the position of each punch block with said mark; and means for separately controlling the displacement means in response to position error information.

Abstract: The invention relates to a machine for exposing a panel to laser radiation, said panel having a working length L in a first direction Y, and being subdivided into N successive segments. The machine has a fixed structure; a horizontal panel support that is movable relative to the structure; device for generating and modulating N laser beams; and N optical units which are fixed relative to the structure. Each optical unit has deflector device for generating a continuously deflected beam, and a mirror for directing the deflected beam towards the panel, the length l1 of the mirror being greater than L/N.

Abstract: The invention relates to a light exposure installation of a double-sided printed circuit plate through a first and a second artwork equipped with a location mark. It includes a first (10) and a second fixed supporting structure in a horizontal plane, a first and a second support of the first and second artworks (12), optical means for detecting the positioning errors between said circuit and said first and second supports, means for moving perpendicularly to its plane, one of said supports towards the other support, means (26, 28) arranged outside the unit made up of said supports and said circuit to maintain said circuit fixed in its plane with respect to said supporting structure; and means (20, 22) for moving independently said first support (12) with respect to said circuit and said second support with respect to said circuit depending on the detected positioning errors.

Abstract: The invention relates to a machine for punching a printed circuit plate. The machine comprises a plurality of punch blocks that are movable relative to the structure. Each block comprises a frame that is movable relative to the structure, displacement means for positioning each frame relative to the structure as a function of instructions received, a non-removable punch die secured to the moving frame and located beneath the plane corresponding to said plate, a punch tool support secured to said frame and disposed above the plane of said plate and positioned relative to the die, said support including means for removably receiving one of a plurality of punch tools adapted to the characteristics of said plate and for positioning said tool relative to the support, and means for controlling vertical displacement of said tool in said support.

Abstract: The invention relates to a device for aligning and supporting an artwork for a light exposure installation of a printed circuit board, whereby the device includes a fixed horizontal supporting structure. The device also includes an artwork support constituted by a rectangular frame and a glass that is integral with the rectangular frame and suitable for receiving an artwork. The device is capable of supporting and lifting the artwork support suitable for maintaining the artwork support horizontal in a given plane and for producing a co-operation which is substantially without any friction between the artwork support and the supporting structure, temporarily securing the supporting structure to the frame of the artwork support, and aligning the artwork support with respect to the supporting structure in a horizontal plane in two orthogonal directions.
