IPC,


I am using IPC - CH - 65 Guide for cleaning PCB's.

I am using an Ionograph Contaminometer to check contamination levels
on populated boards.
Is there a standard max level for the surface area of a board, such
as 1.5ug / SQ CM.

The Ionograph does not quote a standard max level.
I will be greateful for any help you can give.

Best Regards,

Dave,   Quality  Control  Technician.
