Active Align
Process
SUT : Z
3rd SFR thru-focus scan > Cps check & SFR check (BeforeOC)
If CPS > Criteria
3rd Tilt Adjustment
If SFR < Criteria
Throwing Lens
SUT : X Y
Final OC/DOC adjustment > SFR check (AfterOC or BeforeGlue)
Gripper θx, θy
2nd Tilt Adjustment
SUT : Z / X Y
Moving out > Dispensing > Moving back > SFR check (AfterGlue)
SUT : Z
2nd SFR thru-focus scan & CPS/Tilt Calculation
SUT : Z
Glue shrinkage compensation > SFR check (AfterOffset)
Gripper θx, θy
1st Tilt Adjustment
UV Curing > SFR check (AfterUV)
SUT : Z
1st SFR thru-focus scan & CPS/Tilt Calculation
Final SFR check (FinalCheck)
SUT : X Y
1st OC/DOC Alignment
Unload camera module
Load lens & sensor PCB
3 axis rotation on lens gripper
Gripper θx & θy (Pitch & Yaw)
Adjust the inclination of the Lens so that the optical axis of the Lens is as perpendicular to the Sensor as possible to achieve the average SFR of the four corners.
Adjust the Lens inclination
Corner's Peak Align
Gripper θz (Roll)
Holder AA, make sure that the four sides of the Holder and the four sides of the Sensor are as parallel as possible.
Automotive no need
3 axis movement on SUT
SUT X&Y axis
Adjust Sensor that the center is aligned with the Lens optical axis
OC/DOC Alignment
SUT Z axis
Sweep SFR through focus curve to calculate the inclination angle of the Lens.
Adjust the focus distance between Sensor and Lens to get the best SFR value
Sweep SFR through focus curve& curve fitting
CPS Corner Peak Spread/ Tilt Calcuation
θ=atan(CPS/d)
Adjust Sensor Z with Lens height
Best Z Position for Center
Best Z Position for Corners
