Patent DE-4129835-A1 (DE)
Inventor: KRUEGER GUENTHER DR
IPC: H05K1/18
Filed: 1991-09-07
Abstract: The proposal is for a power electronics substrate (1) with a metal plate (3) forming a heat sink and a metal coating (7 to 13) separated therefrom by an insulating layer (5), in which an electrically conductive connection (15) is formed between the metal coating forming a first signal plane and the metal plate (3) forming a ground layer. Several signal planes consisting of insulating layers (5, 19) with appropriate conductive tracks (7 to 13; 21 to 29) can advantageously be formed above the metal plate (3) forming the base. Electronic components (39) are connected to the appropriate conductive tracks only in the uppermost signal plane. The lower signal planes are used solely to make electric connections without crossings. It is thus possible to make very compact substrates even with complex conductive tracks.

Title: Method of removing the surface layers of glass components with laser radiation and apparatus for carrying out the method
Inventor: BARKHAUSEN WINFRIED DIPL PHYS
IPC: B23K26/12
Filed: 1993-06-21
Abstract: The invention relates to a method of removing the surface layers of glass components with laser radiation and an apparatus for carrying out the method. In the method according to the invention, the surface layer is acted upon by this radiation in such a way that it is vaporised (completely or partly). At the same time, the machining point is acted upon by measuring radiation, in particular of a probe laser, and the transmission factor is measured. The removing operation is then controlled as a function of the transmission measurement. The invention is especially suitable for removing weathered layers on historico-cultural stained-glass paintings, such as, for example, in churches.
