Static electricity.

I'm in a bit of a bind. I'm tinkering with the new motherboard and at present it's sat in a cardboard box for easy access (that and i've not found a case yet lol).

 

I have me an antistatic wristband, wire and the mains plug it attaches to however I've noticed that even when wearing it with it connected to the mains, my trousers are still full of static. Even if i touch my trousers against an exposed radiator pipe (eg holding the trousers against it with my hand) the static still doesn't seem to discharge.

Worse i keep feeling it on my shirt too and obviously i don't want to fry a motherboard.

What am I doing wrong here / what can I do? Please don't say work on it in the nuddy lol.

I need a new signature... i'm bored of the old one!

Re: Static electricity.

Is the carpet your standing on the the clothes you are wearing nylon? If they are then stand on a rubber mat if you have such a thing or maybe even a bit of cardboard under your feet to help prevent the build up.

Re: Static electricity.

Your motherboard should be placed on a conductive mat and your wrist band connected to that and also to earth. If you have a large enough antistatic bag they are ideal to rest the motherboard on. You can earth it with a croc clip and lead, else just make sure that you touch it with you bonded hand as much as possible. If you do this then you should be OK, providing of course that you don't sit on the motherboard!

The other thing of course is to do your utmost to not touch tracks or especially open circuit connection pins.

Re: Static electricity.

What is the position if you were wearing those disposable surgeons gloves whilst doing this type of work ?

Would that work or not ?

Re: Static electricity.

Not unless they're electrically conductive and earthed, so no.

Re: Static electricity.

I think glen is meaning the gloves would stop the static travelling across to the motherboard - insulating like they do normal electricity.

Re: Static electricity.

If they're insulated then they can build up static. What you need is to prevent the static from being able to build up by having as much as possible earthed, not insulated.

Re: Static electricity.

So there you have it, don't wear nylons..ooops..that doesn't look right, but you know what I mean.  

A float tip is pleasing in its appearance and even more pleasing in its disappearance.
Growing old is inevitable...But growing up is optional.
