Dear Technos,

 

I need to serialize about 200 BGAs (simply write on them sequential
numbers 1-200). The BGAs will be assembled, SnPb process with water
soluble flux, then washed in plain water in our in-line washer.

 

In case the customer will not accept us scratching the numbers onto the
top of the components, what kind of permanent ink can I use?

 

And would you see any issue with scratching the top of the components?

 

Thanks,

 

Ioan
