Abstract:
The invention relates to a lighting device for a motor vehicle. Said lighting device comprises a gas discharge lamp (1; 96) for emitting light, a starting device for providing a starting voltage for starting the gas discharge lamp (1; 96) and a control device for providing an input voltage for the starting device and an operating voltage for operation of the gas discharge lamp (1; 96). The control device is an integral part of the starting device. In order to come to grips with the problems associated with space and temperature with such lighting devices, the invention proposes that the combined starting and control device (5; 80) has a plug element (6) for connecting a vehicle power supply system voltage (7), the plug element (6) being in the form of a printed circuit board plug, which is formed by conductor tracks (21; 23) guided at an edge of a printed circuit board (20) of the starting and control device (5; 80).
Abstract:
The invention relates to a printed circuit board (60) having an insulating support layer (61) and a layer (62) of conductive material applied thereto. In order to increase the flexibility of the printed circuit board (60), it is proposed that material from the support layer (61) have been removed at least one point on the printed circuit board (60) on a side of the support layer (61) which is opposite the layer (62) of conductive material in order to form a straight groove (63) which extends from one side of the printed circuit board (60) to another side of the printed circuit board (60), so that the printed circuit board (60) can be bent along the groove (63), wherein the material of the support layer (61) which has remained in the region of the groove (63) and/or the layer (62) of conductive material in the region of the groove (63) form(s) a bending edge (64).
Abstract:
There is provided a laser processing apparatus, a multilayer printed wiring board manufacturing apparatus, and a manufacturing method to form via holes of ultra-fine diameter. The laser beam from the CO2 laser oscillator (60) is converted to the shortened wavelength beam by a tellurium crystal (94) to control diffraction of the laser beam. Simultaneously, when the laser beam is condensed, a limit value of the condensation limit is reduced. Thereby, the spot diameter of laser beam is reduced and a hole for via hole is bored on the interlayer insulation resin on a substrate (10). Therefore, even when the laser beam output is raised to form a deeper hole, the hole diameter is not widened and thereby a hole for a small diameter via hole can be formed.
