Abstract

A method for assembling a camera suitable for use for a vision system of a vehicle includes providing a circuit board having first and second sides separated by a thickness of the circuit board. An imager is disposed at the first side of the circuit board and connecting circuitry is disposed at the second side of the circuit board. Solder pads are provided at the connecting circuitry at the second side of the circuit board. A coaxial connector is aligned at the solder pads at the connecting circuitry. The coaxial connector is soldered at the connecting circuitry via the solder pads. The solder pads may include a plurality of outer solder pads and at least one inner solder pad for connecting to respective contact portions of the coaxial connector.

Claims

1. A method for assembling a camera suitable for use for a vision system of a vehicle, said system comprising:

providing a circuit board having first and second sides separated by a thickness of said circuit board, wherein an imager is disposed at said first side of said circuit board and wherein connecting circuitry is disposed at said second side of said circuit board;

providing solder pads at said connecting circuitry at said second side of said circuit board;

aligning a coaxial connector at said solder pads at said connecting circuitry;

determining when said coaxial connector is aligned with said solder pads at said connecting circuitry; and

responsive to determination that said coaxial connector is aligned with said solder pads, soldering said coaxial connector at said connecting circuitry via said solder pads.

2. The method of claim 1, comprising providing a camera front housing and aligning a lens of said camera front housing with said imager and attaching said circuit board at said camera front housing.

3. The method of claim 1, comprising providing a camera front housing and a camera rear housing, and attaching said camera rear housing at said camera front housing to encase said circuit board, wherein said coaxial connector extends at least partially through a connector portion of said camera rear housing when said camera rear housing is attached at said camera front housing.

4. The method of claim 3, wherein said coaxial connector has a cable connecting end opposite the end of said coaxial connector that is soldered at said connecting circuitry, and wherein, when said camera rear housing is attached at said camera front housing, said cable connecting end of said coaxial connector is substantially aligned with and received in said connector portion of said camera rear housing, and wherein said connector portion is configured to attach to a connector of a cable.

5. The method of claim 4, wherein said coaxial connector comprises a metallic material and wherein said camera rear housing comprises a polymeric material.

6. A method for assembling a camera suitable for use for a vision system of a vehicle, said system comprising:

providing a circuit board having first and second sides separated by a thickness of said circuit board, wherein an imager is disposed at said first side of said circuit board and wherein connecting circuitry is disposed at said second side of said circuit board;

providing solder pads at said connecting circuitry at said second side of said circuit board;

aligning a coaxial connector at said solder pads at said connecting circuitry;

determining when said coaxial connector is aligned with said solder pads at said connecting circuitry;

responsive to determination that said coaxial connector is aligned with said solder pads, soldering said coaxial connector at said connecting circuitry via said solder pads;

providing a camera front housing and aligning a lens of said camera front housing with said imager; and

attaching a camera rear housing at said camera front housing to encase said circuit board, wherein said coaxial connector extends at least partially through a connector portion of said camera rear housing when said camera rear housing is attached at said camera front housing.

7. The method of claim 6, wherein said coaxial connector has a cable connecting end opposite the end of said coaxial connector that is soldered at said connecting circuitry, and wherein, when said camera rear housing is attached at said camera front housing, said cable connecting end of said coaxial connector is substantially aligned with and received in said connector portion of said camera rear housing, and wherein said connector portion is configured to attach to a connector of a cable.

8. The method of claim 7, wherein said coaxial connector comprises a metallic material and wherein said camera rear housing comprises a polymeric material.

9. The method of claim 6, wherein the step of determining when said coaxial connector is aligned with said connecting circuitry comprises determining when said coaxial connector is aligned with said connecting circuitry via a contactless measuring system.
