EPM240T100I5N Architecture Variation !

[BtsMalta2022]

Good morning,

I require assistance to understand the difference in the architecture between two batched of the same product, namely EPM240T100I5N.  

The pictures below show the x-ray image & its corresponding marking the of batch with "holes": 

The following pictures, similarly show the x-ray image & its corresponding marking the of batch with " NO holes":

Our difficulty lays in understanding the difference between the two product architectures, the reason for the "holes" in the first batch and why they are not present in the second batch with "NO holes".

Please evaluate my query and kindly let me know your clarifications for this case.

Kind regards

Hi BtsMalta2022,

We are pending for a response from subcon. Will get back to you by today or tmr.

BTW, on the 2nd x-ray photo, the x-ray image seems too dark. Can you lower the contrast so that it looks the same as 1st x-ray photo?

Hi BtsMalta2022,

Just got feedback from the internal. Both designs are normal. The “holes” below are not holes, but dimples on bottom of die pad. It is to enhance mold to die pad adhesion. This is a newer design.
