QFN28-0.5-AS01PGL aging seat

 Actual requirements:

1. Package QFN

2. Number of Pins: 28

3. Number of grounding connections: 3pin

4.Chip size:6*3*0.75mm

5. Test requirements: HAST test 150℃*72 hours in 85% relative humidity;

3. Requirements analysis: Mainly for aging testing, the electrical requirements are not high. The main thing is that the contact impedance needs to be controlled to ok; the test seat structure and all materials need to meet the requirements of testing 150℃*72 hours at 85% relative humidity. Require.

4. Production: Due to the structure of the product, the currently molded shrapnel and its corresponding test seat structure cannot be used, so the more expensive alloy probe structure, that is, the pogo pin structure, can only be used;

5. After production is completed, quality inspection will be conducted on all dimensions of the aging seat, and each dimension marked on the drawing will be strictly inspected. Once it is confirmed, it can be assembled; while assembling, the processing materials of the aging seat need to be placed in the aging furnace for sampling and testing. ;At the same time, after assembly, it also needs to be tested in the same way. Once all the test passes are passed, it can be shipped into the warehouse.
