Patent attributes
A camera for a vehicular vision system includes a circuit board having a first side and a second side opposite the first side. The circuit board has a first coefficient of thermal expansion (CTE). An imager is disposed at the first side of the circuit board, and a lens assembly is optically aligned with the imager. A bend-countering element is disposed at the first side or the second side of the circuit board. The bend-countering element has a second CTE that is different from the first CTE of the circuit board. The bend-countering element counters temperature-induced bending of the circuit board. With the camera disposed at the vehicle, temperature-induced bending of the bend-countering element is in an opposite direction from temperature-induced bending of the circuit board.
