Qualification certificate for reliability testing

Other Parts Discussed in Thread: LMZ14202EXT

Hello, I don't know if this is the right place to ask this but I wanted it to be as generic as possible. Please redirect me if needed.

I'm Gabriel from TEKEVER, I would like to know if you have any kind of certificate or standard of testing that ensures the environmental tests you perform are representative of every batch or somehow ensure batch to batch repeatability.

Another aspect we would like to confirm is if the component reels have parts from the same batch / lot or is there any possibility that parts from different batches are in the same reel?

Among the components from Texas Instruments we have the following: LMZ14202EXT, MSP430F438AIPZR, RM48L952DPGET, CDCLVC1104PW and ADS62P15IRGC25, however I believe this inquiry may apply to the full spectrum of your components.

This has been recently requested by our customer in order to assure reliability and proceed with our components' qualification.

Thank you very much and best regards,
