Abstract:
To improve electronic part packaging efficiency without sacrificing the transmission distance of a radio IC tag, a recess is formed in the front side surface of a printed wiring board. An IC chip is placed in the recess so that the IC chip does not protrude from the front side surface, a first major surface 1a and a second major surface of the printed wiring board. Antenna elements of an antenna are formed on the front side surface on the opposite sides, respectively, of the IC chip, and the antenna is connected to the IC chip. The antenna is a dipole antenna of a length equal to half the wavelength of radio waves to be radiated by the antenna.

Abstract:
An opto-electronic element (1) is mounted on a substrate (2) comprising an electric circuit (3, 3′) with an electrically conducting layer (4, 4′). The opto-electronic element (1) has a body (5) for emitting light in a pre-selected wavelength range and is provided with current conductors (7, 7′) which contact the conducting layer (4, 4′). According to the invention, an adhesive material (8) is used to mount the opto-electronic element (1) on the substrate (2) with clearance with respect to the substrate (2), the body (5) contacting the substrate (2) via the adhesive material (8). Preferably, the adhesive material (8) is a heat-conducting material which serves to cool the body (5) during operation. In order to make a reliable interconnection, the geometry of the current conductors (7, 7′) is optimized in such a way that a small tensile force (order of magnitude 1 N) is present in a weld between the current conductors (7, 7′) and the conducting layer (4, 4′). The tensile force ensures that the opto-electronic element (1) is pressed into the adhesive material (8). The small tensile force is obtained by calibrating the current conductor (7, 7′) during a “press” step in the laser-welding process.
Abstract:
A method and a device for producing an aspiration surface on an object, preferably an electrical component intended for the SMD mounting technique. The planar aspiration surface is formed on the surface located opposite the mounting side of the component by applying an adhesive mass onto the component and molding the mass through cover band arranged above the component with a die to shape the adhesive mass into a planar surface. Following curing of the adhesive mass, the cover band is separated from the mass, resulting in a component with a planar aspiration surface for reliable and unproblematic aspiration, pick-up and transport. The adhesive mass may consist of a liquefiable or volatilizable material such as wax, colophonium or plastic.

A system for detecting certain improperly soldered electrical component connections to a printed circuit board includes methods and apparatus providing an automated means for detecting unsoldered component leads is disclosed. A connection pad divided into two portions, or land areas is bridged by the component lead when soldered. A test pad connected to one of the land areas provides a test point for detecting the presence or absence of an open circuit condition through the lead of an electrical component to a point in the circuit to which it is to be electrically connected.
Abstract:
A built-on control device has a multicomponent housing (15) which is open on one side and is fitted onto the housing block (10) of a hydraulic unit. Arranged in the housing (16) of the built-on control device (15) is a printed circuit board (29) for an electronic circuit with a plurality of electronic components (33). The printed circuit board (29) comprises a plurality of rigid regions (30, 25), one rigid region being formed by the lid (25) of the housing (16). A looplike flexible region (36), which comprises only the conductor foil (31), is located between the two rigid regions (25, 30). In addition, the conductor foil (31) projects beyond the rigid region (30) of the printed circuit board (29) and in this region (28) it is placed in contact with the connection pins (27) of the loads (12) of the hydraulic unit. Since the contact is made directly with the conductor foil (31) in the flexible region of the printed circuit board (29), tolerances can be easily compensated so that contact can be made easily and thus the built-on control device on the housing block (10) can be manufactured easily.
