Abstract
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.
