摘要:
A solder resist coating for a rigid-flex circuit board contains one or more conductor tracks and at least one flex area. The solder resist coating has one or more movement gaps in the flex area of the circuit board. In addition, an electronic module is formed having at least one rigid-flex circuit board with a solder resist coating.

摘要:
A constructional unit has a frame and a cover. The frame and the cover are formed of materials with different coefficients of thermal expansion. A plurality of spacers is arranged between the frame and the cover and defines a gap therebetween. An adhesive is provided in the gap to attach the frame to the cover and simultaneously seal the gap.
摘要:
A housing (1) with at least one electrical connection (7) through a housing wall (4) can be manufactured especially economically and can facilitate an especially economical lacing of electronic components (2, 13) present on the interior and on the exterior of the housing (1). The electrical connection (7) is enclosed by a housing material and additionally sealed by a sealing material (6). The sealing material (6) also advantageously serves to seal a top (3) and a bottom (5) to the housing wall (4). Through the combination of the casing of the electrical connection (7) of the housing (1) and the sealing material (6), this arrangement is, moreover, especially impervious to oil or other aggressive media.
