How to Identify Components and ICs with Foreign Codes ????

[FPTEC]

Hello,

It is increasingly common to find components with strange codes that have no results on google.

This makes identification difficult. What to do to identify in these cases? 

Thank you.

Sometimes the first letters are omitted, so it is hard to find it if you don't know the full name. Can you post a picture? Maybe we can identify it. Apart from that, those could also be custom-made ICs.

It is not a specific case, the goal is to know methods that can be used in front of all this.

Yes, I usually know many ASICs in my area of expertise ...

Only the majority is not ...

And they are often identified by sites of destruction, as I do not know, but are identified.
