Abstract

Printed circuit board arrangement (10) for a motor vehicle headlight, comprising a printed circuit board (50) and a heat sink (60), which are spaced apart from one another by a distance (X) at least in some areas in such a way that a gap (70) is formed between the printed circuit board (50) and the heat sink (60), wherein the printed circuit board (50) is attached to the heat sink (60) with at least one attachment device (80) while maintaining the gap (70), wherein the at least one attachment device (80) comprises the following:

an attachment opening (100), which attachment opening (100) completely passes through the printed circuit board (50),a recess (200), which is arranged on the heat sink (70), and which has an insertion opening (210),an attachment element (300) with a longitudinal axis (A), whereinthrough exertion of a force (F) on an engagement section (310) and an opposing force on a contact section (320), the attachment element (300) is deformed in such a way that the attachment element (300) is clamped in the recess (200) in a form-fitting manner and a first and a second widening section (330a, 330b) of the attachment element (300) is formed, wherein the first widening section (330a) extends into the gap (70) and beyond the opening size of the attachment opening (100) such that the first widening section (330a) supports the printed circuit board (50), wherein the second widening section (330b) extends radially to the longitudinal axis (A) beyond the opening size.
