Abstract:
Method for casting around an electronic circuit, of the type used in distance-measuring systems in motor vehicles, comprising the steps of:placing the electric circuit on a centering holder arranged movably inside a casting mold shell and inserting the electric circuit into a casting mold,supporting the electric circuit with a spreader that is insertable into the casting mold wherein the spreader projects with at least one distance finger into the casting mold to support the electric circuit;closing the casting mold and filling the casting mold with a slow-setting plastic, wherein the plastic partially sets during filling,withdrawing the centering holder during setting but prior to solidification from the casting mold;withdrawing the distance finger from the casting mold during setting at a different time than withdrawing the centering holder but prior to solidification; andremoving after solidification the cast-around electric circuit from the casting mold.
