Patent DE-3231056-A1 (DE)
Title: Method for fitting unwired components on to printed circuit boards
Inventor: ZEILBECK RUDOLF
IPC: H05K3/30
Filed: 1982-08-20
Abstract: While fitting planar components having flat connections on to a printed circuit board, the problem arises that these components should not be subjected to the liquid solder and therefore cannot be fitted on the solder side of the printed circuit board. According to the invention, holes are therefore produced in the printed circuit board, and the planar components are bonded on to the component side of the printed circuit board before being soldered on. Contact is made with the components by means of solder which rises through the holes and connects the flat connections of the planar components to the metallised walls of the holes and to solder surfaces. The invention is used especially in the production of complete printed circuit boards which, in addition to planar components having flat connections, also include components having wire connections. <IMAGE>

Title: Device for optical distance measurement, in particular for measuring profiles of workpieces or cutting edges of tools
Inventor: BREITMEIER ULRICH DIPL PHYS DR
IPC: G01B11/24
Filed: 1983-04-29
Abstract: An optical device for measuring profiles and, in particular, cutting edges of tools has a laser whose light is focused onto the profile to be determined. The light spot produced in this way is projected by means of projecting optics onto an optoelectronic receiving device to which there is connected an electronic evaluating device for producing an electrical distance signal which depends on the light of the light spot on the optoelectronic receiving device. Arranged in the beam path of the light emitted by the laser and in that of the projecting optics are tiltable or rotatable mirrors which can be moved in the same sense and synchronously, e.g. oscillate, in such a way that the location of the light spot moves on the profile to be measured and in this case the location of the light spot is situated on the optoelectronic receiving device in all deflecting positions of the laser beam on the optoelectronic receiving device. The device facilitates simple, rapid and accurate scanning of fine profiles such as, e.g., cutting edges of tools, there even being the possibility of representation on a screen. <IMAGE>
