Abstract: A holder for exposing both faces of a panel to light in order to make a double-sided printed circuit using first and second flexible artworks. The holder has a first frame with no transparent plane support member for receiving the first flexible artwork, and a second frame with no transparent plane support member for receiving the second flexible artwork. The holder includes a system for positioning and fixing the peripheries of the artworks to their respective frames. The holder further includes a mechanism for positioning and holding the panel between the frames. There is an approach mechanism for causing the frames to move towards the faces of the panel. There is also a system for establishing suction in the volume defined between the frames having the panel therebetween.

Abstract: An apparatus for exposing a light sensitive surface (e.g., a printed circuit board) to light. An optical processor subsystem, which includes a reflector and an integrator-collimator assembly, processes light from a light source to produce a uniform and collimated light beam having a mean angle of incidence relative to the light sensitive surface of less than or equal to 2° and having illumination uniformity that departs by less than ±10% from a mean value. An optical light shaper subsystem transforms the uniform and collimated light beam into a uniform and collimated light strip. A displacement mechanism provides relative movement between the light strip and the light sensitive surface. A speed matching mechanism matches the speed of relative displacement to the brightness of the light strip and to the sensitivity of the light sensitive surface. The light source remains stationary in one construction and moves relative to the light sensitive panel in another construction.

Abstract: A device is provided for holding a printed circuit panel having two substantially parallel margins. The device has a frame and employs two grasping jaws to hold the first and second margins of the panel, respectively. An actuator coupled to one of the grasping jaws provides a force that tends to move away one grasping jaw with respect to the other grasping jaw and thereby provides a tension to keep the printed circuit panel plane. Since the printed circuit panel is grapsed by and traction is exerted on the two parallel margins, the panel is held with highly accurate planeness regardless of its dimensions and of its thickness. In This manner, the device for holding a printed circuit panel may accommodate panels with a wide variety of sizes.

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.

Abstract: A first tool assembly includes a punch holder assembly and a circuit board clamp and a second tool assembly includes a die for receiving punches held and driven by the punch holder assembly. A circuit board has holes formed by the punches and is clamped by the clamp to the die. The circuit board and die are aligned to the punch assembly by an alignment pin secured to the punch assembly operated independently of the operation of the punch assembly. The punch assembly and the clamp are independently controlled by actuators with a convex distortion of the punch assembly and clamp during punching to provide an improved clamping and punching action.

The antenna is provided with two systems of lines (1) whose ends (3, 30) form probes emerging into wave-guides (2). The probes of one system (3) are perpendicular to those of the other system (30). Between the two systems of lines there is placed only a thin sheet (150) bored with cross-shaped cut-outs (6), and provided with separating studs made from a silk-screen-printed insulating material.

Abstract: The invention relates to a data bus connector or a connector for another complex high-speed electronic application. In accordance with the invention, the connector comprises a plurality of substrates (4, 5, 6) which are arranged at a plurality of mutually substantially parallel levels. Active circuits (10) are mounted on the substrates (4, 5, 6) and are connected between input pins (2) to be connected to an external connector and pins (1) which are to be soldered to a printed circuit card (28). The connector pins (2) are straight and secured flat against the edge of the substrates (4, 5, 6) carrying the active circuits (10); the spacing between two substrates thus corresponds to that between two rows of pins. The pins (1) to be soldered extend perpendicularly to the pins (2) of the connector and are also secured to the substrates.

Abstract: Stackable modules for electronic subsystems, which are all mechanically identical, but functionally different, which can be disassembled and rearranged. Each module has a housing of two parts, in which an electronic circuit is fixed and which has openings, through which the electronic circuit is electrically accessible. It has recesses for fixing a rod provided with metallic wires, which ensure contacts with the electric circuit and project beyond the exterior of the housing. When several housings are assembled, the wires, which project beyond the exterior of each housing, are in contact with the electronic circuit of the adjacent housing via the openings of the latter.

Abstract: Electronic components are mounted on a substrate from thin-walled magazines which are arranged in a configuration corresponding to a desired implantation of the components. Stacks of components are pushed upwards in the magazines by a pulse of compressed gas in order to press the components against the substrate which has been arranged over the magazines with conductor tracks facing downwards. Local application of an adhesive solder paste to the substrate causes the component on the top of each stack to adhere to and be lifted simultaneously with the substrate.
