Step 3Grinding
After you cut the RAM or any other PCB with the hack saw, you will want to smooth off the edges. To do this, start up the rotary tool with the grinding attachment of your choice.
To get a nice finish, glide the tool head over the rough edges of the RAM. I rounded off the bottom edges, but it is not necessary to do this. Slide your fingers across the newly ground edge and continue until it is satisfactory smooth to the touch. The edge probably will not look very uniform, but it isn't very large, and does not detract too much from the final product.
Let me remind you, PCB dust is nasty, so wear a mask. When grinding, you will produce the most dust, so make sure you are not breathing it in. Also, whenever using a rotary tool, use eye protection. You may encounter a loose resistor or something of the type while you are grinding the RAM, which could potentially become a projectile flying at your eye.
