Abstract

A system and method for testing a wireless earpiece which provides improved efficiencies in manufacturing. Automated testing of one or more printed circuit boards of the wireless earpiece is initiated. The semi-assembled wireless earpiece is tested. End-of-line functional testing is performed. Final acoustic testing of the wireless earpiece is performed.

Claims

1. A method for testing a wireless earpiece, the method comprising:

initiating an automated production panel testing, wherein a plurality of PCB (printed circuit boards) are produced on the automated production panel;

conveying the production panel to a first rework station if a failure occurs with the production panel during testing;

correcting the failure and returning the production panel back for automated production panel testing; and

rejecting the production panel if the failure cannot be corrected.

2. The method according to claim 1, further comprising the steps of:

performing semi-assembly testing of the wireless earpiece;

conveying the semi-assembly to a second rework station if a failure occurs with the semi-assembly during testing;

correcting the failure and returning the semi-assembly back for semi-assembly testing; and

rejecting the semi-assembly if the failure cannot be corrected.

3. The method according to claim 2, further comprising the step of performing end-of-line functional testing.

4. The method according to claim 3, further comprising the step of rejecting the wireless earpiece if a failure is detected during end-of-line functional testing.

5. The method according to claim 4, further comprising the step of performing final acoustic testing on the wireless earpiece.

6. The method according to claim 5, further comprising the step of rejecting the wireless earpiece if a failure is detected during final acoustic testing.

7. The method according to claim 6, further comprising the step of packaging the wireless earpiece.

8. A system for testing a wireless earpiece, the system comprising:

a computing device operably coupled to a production panel for automated testing, wherein a plurality of PCB (printed circuit boards) are produced on the production panel, wherein the PCBs are components of the wireless earpiece;

a first rework station for receiving a failed production panel from the computing device; and

a first monitor operably coupled to the first rework station providing data regarding the reason for the production panel failing;

wherein the failed production panel is rejected if the first rework station cannot repair the failed production panel and the failed production panel is returned to the computing device for production panel automated testing if the failed production panel can be repaired or defective components can be removed to prevent integration into a semi-assembly.

9. The system according to claim 8, further comprising a second rework station for receiving a failed semi-assembly from the computing device;

and

a second monitor operably coupled to the second rework station providing data regarding the reason for the semi-assembly failing;

wherein the failed semi-assembly is rejected if the second rework station cannot repair the failed semi-assembly and the failed semi-assembly is returned to the computing device for semi-assembly testing if the failed semi-assembly can be repaired.

10. The system according to claim 9, wherein the computing device performs end-of-line functional testing.

11. The system according to claim 10, wherein the wireless earpiece is rejected if a failure is detected during end-of-line functional testing.

12. The system according to claim 11, wherein the computing device performs final acoustic testing of the wireless earpiece and rejects any failed wireless earpiece.

13. The system according to claim 11, wherein the wireless earpiece is packaged.

14. A method for testing a wireless earpiece, the method comprising:

initiating an automated production panel testing, wherein a plurality of PCB (printed circuit boards) are produced on the automated production panel;

conveying the production panel to a first rework station if a failure occurs with the production panel during testing;

correcting the failure and returning the production panel back for automated production panel testing;

rejecting the production panel if the failure cannot be corrected, wherein defective components are removed before being integrated into a semi-assembly;

performing semi-assembly testing of the wireless earpiece;

conveying the semi-assembly to a second rework station if a failure occurs with the semi-assembly during testing;

correcting the failure and returning the semi-assembly back for semi-assembly testing; and

rejecting the semi-assembly if the failure cannot be corrected.

15. The method according to claim 14, further comprising the step of performing end-of-line functional testing.

16. The method according to claim 15, further comprising the step of rejecting the wireless earpiece if a failure is detected during end-of-line functional testing.

17. The method according to claim 16, further comprising the step of performing final acoustic testing on the wireless earpiece.

18. The method according to claim 17, further comprising the step of rejecting the wireless earpiece if a failure is detected during final acoustic testing.

19. The method according to claim 18, further comprising the step of packaging the wireless earpiece.

20. The method according to claim 19, further comprising the step of testing component sets of a PCB for energy consumption.
