A system for assembling a camera for a vision system of a vehicle includes a circuit board having an imaging array sensor disposed thereat, with the circuit board having connector circuitry at a side thereof. A lens barrel is provided and the circuit board is attached at the lens barrel. Solder pads are provided at the connector circuitry. A coaxial connector is provided and the coaxial connector is aligned with the connector circuitry at the circuit board. The system includes determining when the coaxial connector is aligned with the connector circuitry at the circuit board. When the coaxial connector is determined to be aligned with the connector circuitry, the coaxial connector is attached at the connector circuitry, with attaching the coaxial connector at the connector circuitry including soldering the coaxial connector at the connector circuitry via the solder pads.
