  11. Check that dowel pins touch groove and the left one is roughly centered.
  12. Open vacuum valve (2), pushing hybrid towards dowel pins.*
  13. Check rotation of the hybrid using the crosshairs and the notches on the top edge of the hybrid.
  14. Check that vacuum valves (5) & (6) are off.*
  15. Bring platform home (towards you until it stops).
  16. Check vacuum pen and take first sensor.
  17. Check sensor serial number (make sure it’s Type 5). POSITION #0:
  18. Place sensor on left jig.
  19. Align edge of sensor with hybrid. Move the sensor back very slightly before putting on vacuum.*
  20. Add safety plug and open valve (5) to turn on vacuum.
  21. Tap sensor very gently with dental tool to verify vacuum is holding.
  22. Correct sensor rotation.*
  23. Position sensor left/right using hole in hybrid.*
  24. Adjust distance of sensor from hybrid.*
  25. Place second sensor on right jig, checking serial number and type is 3. POSITION #2:
  26. Add safety plug and open valve (6) to turn on vacuum. Tap to verify that it is on.
  27. Repeat steps 22 to 24 to correct rotation and position of right sensor.
  28. Recheck position of both sensors left/right and front/back.
  29. Slowly release glass pieces, watching the glue flow into the hybrid-sensor gap.*
  30. Check the positioning of the glass pieces and the glue joint.*
  31. Recheck sensor position left/right and front/back. One option is to measure relative to notches.*
  32. Move stage all the way back so module is protected under microscope.
  33. Let glue cure (keep samples and check …12 hours minimum).
  34. Switch vacuum valves (5) & (6) off and remove safety plugs.
  35. Stop vacuum for hybrid by closing valve (2).
  36. Remove module from gluing station.*
  37. Reinforce glass glue joints.*
  38. Move sensor jig to right position, raise it and roughly center it both left/right and front/back.
  39. Check if glass piece holder is in the DOWN position, held by clamps on top of platform.
  40. Verify stage rotation using dowel pins.
  41. Prepare HIGH glass piece (GPH), keeping glue sample.
  42. Put glass piece on the holder with the high side towards the sensor. Check that it is flat.
  43. Place module back on the station. Switch on hybrid vacuum using valve (2). Check that dowel pins touch notches and verify hybrid rotation using notch alignment.
  44. Verify that sensor jig vacuum (5) is off, removing safety plug.
  45. Check vacuum pen and take sensor (checking number and Type 5). POSITION #1:
  46. Add safety plug and turn vacuum on using valve (5).
  47. Follow steps 22 to 24 to correct sensor rotation and position.
  48. Slowly release glass pieces, watching the glue flow into the hybrid-sensor gap
  49. Check glass piece positioning and glue joint.
  50. Recheck sensor position left/right and front/back. One option is to measure relative to notches.
  51. Let glue cure. (At least 12 hours)
  52. Stop vacuum (valves 2&5), remove safety plugs.
  53. Remove completed module.
  54. Reinforce glass glue joints.

 

Notes on individual steps

3) Adjust stage rotation with knob R1 (on the cylinder underneath gluing jig and above motorized platform). Trust the left/right motion of the stage. Do not use the counter, it drifts.

5) Use knob R4 (black knobs on sides) to raise/lower sensor jigs. It is pushed left/right by hand.

6) See separate instruction sheet. When changing hybrid type, check glass piece fit (especially height) first.

9) Glass pieces must sit flat and all the way down in the groove in the holders.

10) Lower back of hybrid first, then front so you don’t hit the glue.

12) Follow vacuum tubes to check which valve connects to which part of the jig.

14) To ensure vacuum is off, remove and replace safety plug.

19) You can use front/back movement screw on the sensor jig to push sensor against hybrid.

22) Use the guard trace along the top edge of the sensor (some have cross-hairs at the corners) to check rotation. Use R2 (silver knob under front of sensor jig) to correct sensor rotation.

23) Set distance from center of hole in hybrid to center of flanking bonding pads on sensor to be 1.6000 mm. Use the hole slightly to the left of the sensor center for this positioning. Use S2 (black knob under and to the outside of the sensor jig) to move it left/right.

24) Set distance from center of hole in hybrid to top edge of inner guard trace equal to 1.450 mm. Use the hole slightly to the left of the sensor center for this positioning. Use S1 (black knob under front of sensor jig) to move it front/back.

29) Use the wide field on the microscope. Be prepared to move the glass piece back if glue overflows.

30) Using the microscope, you can see glue in the gap between the sensor and hybrid. Looking from the side and below, you can see how the glass piece is positioned.

31) From the edge of the notch on top of the hybrid to the top edge of the inner guard trace is 22.750 mm. From the edge of the notch on the left side of the hybrid to the left edge of the inner guard trace is 8.570, 50.590, and 92.620 for positions 0, 1, and 2, respectively.

36) You should rotate the module up to remove it. You may need to lift corner with a razor blade.

37) See separate gluing instruction sheet.
