Hi,
Recently we bought & recived components (MPN LIS2DH12TR) from distributor (Mxxxxx) are over two years old date code, which exceeds the threshold for our internal testing policy.
As you know, there's a potential risk of pad oxidation affecting solderability over time.
For our validation process, we conduct solderability tests on:
- Active components that have exceeded 2 years of storage. (Apply to this component)
- Passive components that have exceeded 5 years of storage.
Does STMicroelectronics has any official statement confirming that the shelf life of these LCA leadless pads ? We would want to confirm the product recived direct from distributor (Mxxxxx) which more then xx period are still useable or not direct into our production.
Best regards,
Mr. Weng
