QFN56-0.4 positioning receiver ATE test socket
1. Actual requirements:
1.Package: VFQFPN56 package
2. Number of Pins: 56
3. Number of grounds: 4pin
4. Chip type: positioning receiver chip
5. Test requirements: Product firmware burning purpose
3. Demand analysis: Since the chip spacing is 0.4mm, its spacing and chip size are also relatively special. In addition, the chip functions as a positioning receiver and is very sensitive to frequency and received signals. It needs to adapt to the frequency, contact The impedance requirements are very high, but according to the actual information provided by users, their actual application is mainly for burning firmware. In this regard, the requirements for the test socket are not that high, so the actual function is limited to burning firmware. Just record.
4. Production: It is not difficult, mainly the matching work of 0.4mm spacing, and the structural design of the ATE pressure test socket, which facilitates pick-and-place and chip contact.
5. After the production is completed, quality inspection will be conducted on all sizes of the test socket, and a power-on test will be conducted to confirm whether the product is OK. After the power-on shooting and adaptation are sent to the user for confirmation, the product can be shipped.
