Key points for purchasing QFN burn-in socket: How to ensure the accuracy of IC burn-in test?

QFN burn-in socket is an important equipment for IC burn-in test, so correctly purchasing QFN burn-in socket is crucial to ensure the accuracy of IC burn-in test. This article will introduce the key points for purchasing QFN burn-in socket from six perspectives:

1. Size requirements: The size of the QFN burn-in socket is related to the IC package size. Therefore, users must first consider the IC chip package size that they need to burn in to test to determine the required QFN burn-in socket size.

2. Thermal model requirements: The thermal model of the QFN burn-in socket should be determined based on the IC package type and thermal demand, which will have an important impact on the accuracy of the test.

3. Temperature control requirements: The temperature control requirements of the QFN burn-in seat must be precise and stable to ensure the accuracy of the test results.

4. Power supply requirements: The power supply requirements of the QFN burn-in socket are also related to the packburn-in of the IC chip. If you understand the chip packburn-in information, you can choose the appropriate QFN burn-in socket based on voltage and other parameters.

5. Safety requirements: The QFN burn-in socket must provide sufficient security to ensure the safety of the chip during the burn-in test process.

6. Compatibility requirements: In order to ensure the compatibility of the QFN burn-in stand with other equipment, users need to consider its compatibility with the test system to ensure the smooth progress of the test process.

The above is a basic introduction to the key points for purchasing QFN burn-in socket, but there are other aspects that need to be considered, such as the material requirements of QFN burn-in socket, and users need to consider the cost performance and service life of QFN burn-in socket, etc. In addition, when purchasing QFN burn-in sockets, users also need to consider the supplier’s reliability, after-sales service and technical support, etc. Only by considering many aspects can we ensure that the purchased QFN burn-in socket can meet the needs of users, thereby ensuring the accuracy of IC burn-in testing.
