How to properly ground myself?
- Thread starter ricas123

I rest 1 hand on the case at all times.
When I pick up a component I pause for a moment, and if at all possible I touch my other arm/hand to the case as I am placing the part into the case.
I've never damaged a part as far as I know. Also don't touch any exposed traces of connection points or contacts. Handle the edges of the boards when you can.

Depends on how perfect you want the ground to be, which depends on how much risk you are willing to take with your components. Working with a new component on your desk on a dry day, you ideally want the component, the desktop, the case, and you to be at the same potential. What's described above is good enough for working inside the case, but poses a theoretical risk to a new component.
A reasonable extreme is a conductive mat connected through appropriate resistors to your wrist and your case. I think these are 1 to 10 megaohm resistors, but it's a safety issue so be sure if you go this path. A professional workstation would have the above tied to a grounding mat to stand on, tied to a good earth, with appropriate resistors to limit current flow.
The wrist band should be grounded to the mat. The case should be grounded to the mat, or on the mat. Components should be kept on the mat. Here's a homemade solution AS AN EXAMPLE; I do not endorse its safety: http://www.instructables.com/id/Grounding-an-ESD-mat-and-wrist-band-at-home/ .
I personally use a grounding mat on my table for components, tied to the case and separately tied through a resistor to my wrist strap.
