2718 series digital silicon microphone chip test socket (microphone test socket)
1.Package: crystal oscillator type package
2.Pin number: 3-4Pin
3. Number of grounding connections: 0pin
4. Chip type: 2718 series digital silicon microphone (mainly used in TWS headsets)
5. Test requirements: chip aging test and programming and debugging purposes
3. Demand analysis: The chip size of the 2178 series is 2.75*1.85*0.9mm. The small size of the chip places high requirements on the limit design of the test socket. Depending on the sound input conditions of the chip, the connection pads have 3Pin and 4Pin. The mainstream sound input It is divided into upward sound, downward sound, and side sound; the test requirement is to increase the introduction of air and conduct the corresponding functional aging test while the normal chip is turned on and acoustically tested; thereby cooperating with its aging test
4. Production: Flip-top test seat head, add an M8 air connector to match the input gas, small-volume chip limit design; openings on the top and bottom of the chip to match the chip's radio function; other electrical connection requirements are not required High, it can be turned on and ensure the transmission of mathematical signals;
5. After production is completed, the air holes and sound-receiving holes need to be tested, and the matching can be done with the customer;
