Title: ELECTRONIC UNIT AND METHOD FOR DESIGNING AN ELECTRONIC UNIT
Abstract:
The invention relates to an electronic unit (100, 100') comprising at least one printed circuit board (10, 10', 20) which is populated with a plurality of electric and/or electronic components (50, 50.1, 50.2) on one side or on both sides and which is incorporated into at least one protective housing (90) made of a solidified potting compound (80'). In the process, the electronic unit overall forms a volume body (200) in which the solidified potting compound takes up a filling volume (70). In order to minimize the filling volume, the electronic unit additionally comprises a separate insert molding part (60) which is arranged at least adjacently to a populated side of the at least one printed circuit board and which takes up a spatially closed displacement volume in the volume body with respect to a flowable potting compound for forming the protective housing in a solidified state (80').
