Hi Keyur,

Could I have some clarification on where these batch codes came from? Are they written on the topside of each chip package?

Also, what is the purpose of your inquiry of the significance of these markings?

Thanks!

Hi Chad,

Yes, these batch codes are written on the topside of each IC.

The purpose behind this inquiry is to understand the meaning of batch code, to check date code.

For any query please revert back.

Awaiting reply.

Hi Keyur,

The first two numbers written on the top of each IC represents the year and month respectively.

For example, your first batch code would signify May 2018 (8 -> 2018 & 5 -> May).

It seems that you're missing a number on the second batch code, however I would guess they were made the same year & month (85).

Thanks!
