iphone camera dissection

From DealExtreme, I got these tiny iPhone camera modules (sku.16945) and was hoping to get the specs, but no luck. So I thought, why not sacrifice one.

The heat gun melted off the lens in no time. Scratching off the last bits of plastic dirt reveals, as the rumours suggested:

  • It’s a SOC2020 or MT9D112 sensor (Aptina), respectively SpecTek WXMK15A in a special package
  • The sensor is protected by a glass layer
  • The bond wires are connected to a ceramic carrier
  • The ceramic carrier is directly soldered onto the flex

Unfortunately, the sensor pinout is still a secret, and I still don’t have an iPhone myself to probe. Perhaps it’s time for some good guessing?

Opening this beast, reveals some more details as shown in the pictures below. Also, we find out more about the sensor:

K14L die
K14L die, bonded to flex
  • It’s seems to be identical with the SpecTek part #WXMK15L
  • It’s bonded directly on the flex cable without protection. The bond wires can be damaged very easily when trying to buzz through the connections
  • The autofocus is a piezo spiral, driven by high voltage which is generated on the camera module by a DC/DC converter
