Pilot Run & Test Fixtures
As we mentioned last time, we have encountered the outer case problems. We are still working hard in solving the problems. The good news is that all the problems have been identified with solutions, but the bad news that we need more time for the fixes, and the delivery time will be delayed for another month.
During the past few weeks, we have been testing with pilot runs in our production line, and fixing problems up and down. To automate the production tests at assembly line, we have put together a home-grown test fixture to accommodate the needs of JackPair’s hardware testing.
With the hardware test fixture and our automatic test suites software in place, we are able to identify more production issues. For example, we were able to identify the source of audio noises on some of the boards under certain circumstances. We are also conducting more functional tests to make sure the audio quality is good. This full test fixture automation allows us to test every board before it goes out of our door and into your hands.
During our pilot production run, we’ve encountered another surprise on the outer case; after electroplating, the outer case of JackPair cannot fit into the holding fixture of our Ultrasonic welding machine. We didn’t take into consideration the increased thickness of outer case caused by its electroplating. The increased delta is only less than 0.04 millimeter, which is thinner than human hair, but yet our toolings and fixtures have such high-precision that the slightly increased delta can cause fitness problems here.
Overall, we’re tying up all the loose end, and building up the testing framework to ensure high quality products. To make sure there’s enough time to get everything done in the right way, we’re moving the delivery date to end of August now. Thank you for your patience and support.
