a positioner configured to move the electronic device from the first receptacle, along the second direction, into the second receptacle to a position where the conductive signal pad is in electrical contact with the conductive signal terminal.
2. The apparatus of claim 1 wherein:
the first receptacle is larger than the electronic device; and
the second receptacle is smaller than the first receptacle.
3. The apparatus of claim 1 wherein the first receptacle includes a side wall having a first portion that extends from and is substantially perpendicular to the bottom, and a second portion that extends from the first portion and tapers outward, wherein the second portion is configured to guide the electronic device into the first portion using gravity.
4. The apparatus of claim 1 wherein the holder includes a cover disposed over the second receptacle.
5. The apparatus of claim 1 wherein the holder includes a removable cover disposed over the second receptacle.
6. The apparatus of claim 1 wherein:
the second receptacle includes an end wall having an opening; and
the positioner is configured to generate, within the second receptacle via the opening, a pressure that is different from a pressure outside of the second receptacle.
7. The apparatus of claim 1 wherein:
the second receptacle includes an end wall having an opening; and
the positioner is configured to generate, within the second receptacle via the opening, a vacuum that holds the electronic device in a position in which the conductive signal pad contacts the conductive signal terminal.
8. The apparatus of claim 1 wherein:
the second receptacle includes an end wall having an opening; and
the positioner is configured to generate, within the second receptacle via the opening, a pressure sufficient to eject the electronic device from the second receptacle into the first receptacle along a direction opposite to the second direction.
9. The apparatus of claim 1 wherein the holder includes a sensor configured to indicate whether the electronic device is positioned within the second receptacle such that the conductive signal pad contacts the conductive signal terminal.
10. The apparatus of claim 1 wherein the positioner is configured to move the electronic device from the first receptacle into the second receptacle by moving the holder back and forth.
11. The apparatus of claim 1 , further comprising a tester coupled to the conductive signal terminal and configured to test the electronic device while the electronic device is disposed in the second receptacle.
12. The apparatus of claim 1 , further comprising the electronic device.
13. A method, comprising:
moving an electronic device having a conductive signal pad in a first linear direction to place the electronic device into a first receptacle of a holder, the first receptacle having a bottom and a side wall having a first portion that extends from and is substantially perpendicular to the bottom; and
causing the electronic device to move in a second linear direction substantially perpendicular to the first linear direction from the first receptacle into a second receptacle of the holder so as to place the conductive signal pad into contact with a conductive signal terminal disposed in said second receptacle of the holder, wherein the second receptacle shares the bottom and the side wall with the first receptacle.
14. The method of claim 13 , wherein moving the electronic device includes placing the electronic device into the first receptacle with a pick-and-place machine.
15. The method of claim 13 , wherein causing includes:
moving the holder in a first vibration direction according to a first velocity profile; and
moving the holder in a second vibration direction opposite to the first direction according to a second velocity profile.
16. The method of claim 13 , wherein causing includes:
moving the holder in a first vibration direction according to a first acceleration profile; and
moving the holder in a second vibration direction opposite to the first direction according to a second acceleration profile.
17. The method of claim 13 , wherein causing includes:
moving the holder in a first vibration direction such that the electronic device moves toward the second receptacle; and
moving the holder in a second vibration direction opposite to the first direction such that the electronic device does not move away from the second receptacle.
18. The method of claim 13 , wherein causing includes:
moving the holder in a first vibration direction such that the electronic device moves a first distance toward the second receptacle; and
moving the holder in a second vibration direction opposite to the first direction such that the electronic device moves a second distance away from the second receptacle, the second distance less than the first distance.
19. The method of claim 13 , wherein causing includes:
moving the holder in a first vibration direction such that the electronic device moves toward the second receptacle; and
moving the holder in a second vibration direction opposite to the first direction such that the electronic device does not move.
20. The method of claim 13 , wherein causing includes moving the holder back and forth multiple times.
21. The method of claim 13 , wherein causing comprises:
reducing a pressure in the second receptacle;
creating a pressure differential between the first receptacle and the second receptacle; and
overcoming a friction between the electronic device and the holder using the pressure differential until the conductive signal pad is in contact with the conductive signal terminal.
22. The method of claim 21 , further comprising:
increasing the pressure in the second receptacle after the conductive signal pad is in contact with the conductive signal terminal;
creating a negative pressure differential between the first receptacle and the second receptacle; and
ejecting the electronic device from the second receptacle into the first receptacle using the negative pressure differential.
23. The apparatus of claim 1 , wherein the first direction is vertical and the second direction is horizontal.
