Hi, is just that i have a circuit board that i designed, but i would like to hide one of the Integrated Circuits that is in the board for it not to be known by anyone, and i've seen that in some boards there are some integrated circuits covered with a black paste, and i would like to know what is that paste and where could i get it. thanks in advanced.
 

The easiest is to use very fine sandpaper and remove the number. You can also use a dremel tool with abrasive tip attachment.

Putting a dark color resin mix over the parts is another option, but can be removed by some chemicals. The most secure would be the abrasive techniques.

The one you are talking is called COB. COB itself is MCU. The best way is simple remove the part number.
