Arrangement, e.g. for LCD control in a motor vehicle board computer, for electrically connecting the terminal tabs of two boards with a printed-circuit film

摘要

An arrangement, for example for reliable, vibration-resistant LCD control, in a long term stable manner, in a motor vehicle on-board computer, for the electrically conductive connection (Z) between a large number, for example 20 or 200, of different terminal tabs (A) of a first board (L), for example of a printed-circuit board or of an LCD panel (L), on the one hand, and an equal number of individually allocated terminal tabs (A) of a second board (P), for example of a printed-circuit board (P) which is furnished with electronics, on the other hand, wherein: - the large number of terminal tabs (A) of both boards (L, P) are in each case fitted in a long row, closely adjacent to one another (e.g., along the edges K) on the relevant board (L, P), - a flexible printed-circuit film (F) carries at least the same number (in general without crossings) of intermediate lines (Z), fitted in the form of a layer adjacent to one another, which (Z) in each case produces the connection between the terminal tabs (A) of the first board (L) and the individually allocated terminal tabs (A) of the second board (P), - each intermediate line (Z) contains an adhesive (B), which can be bonded by means of heat and additionally includes metal bodies as a conductor material, at least before the connection of the terminal tabs (A) in those two sections (B) in which they are to be connected in each case to terminal tabs (A) of the boards (L, P), which adhesive (B), for its part, is heated during production of the connections, ("deposition") and is pressed to a greater or lesser extent on to the relevant terminal tabs (A), and - one or more elastic bodies (S) are pressed by means of one or more holders (H) on to the printed-circuit film (F), at least in the region (B) of the already deposited connections (A, B) to the terminal tabs (A).
