Anti-static measures when repairing in a car?

The problem with a wrist strap is it has to be grounded to something. The OP will have to find a point that is connected to chassis. Just don't waste money on a wireless wrist strap.

I can't imagine fixing phones in my car...just the though of dropping something like a screw or those d@mn mini flexes etc that Apple loves to include in their devices.

Shudder!

Hopefully the OP has a minivan or larger vehicle.

Yes, that is exactly my question - how do I ground myself in a car? And is it even necessary when sitting in a car?

I have a larger vehicle ;)

Well, the real danger, from a static perspective, is the potential voltage differential between you before you walk in the car and when you sit in the car.

The car is not really earth-grounded (some say certain tire types are conductive) but you should connect to the chassis ground. I would also use an ESD mat so that you , the mat and the DUT (device under test) are all at the same potential.

You could easily attach the wristband to the steering column, or bolts holding the seat into the car frame. I really don't think esd would be that big of a deal. And a magnetic mat would help you keep all those small pieces in place

@theimedic - Hold that thought! ESD is a big problem. I'm with Minho here.

The real issue is the difference between you, tools, parts and the device. Also make sure your seat and carpet is not a static source!

Using a mat & strap which is tied to your cars bare metal body should do it.
