16x BDR-209 and electrostatic charges

:crackup:


When I mount the new laser I will put ground screws everywhere, even on the mouse.

Make sure you do!
Also don't forget to ground your pack of ground screws.

You might use another ground screw for that.

Exactly, Radim you are a genius! :crackup:

I know, Oliver. :crackup:

try to use a antistatic wrist strap when wirking directly with the diodes...maybe you have a floating ground on the pc or a ground loop on your house, i've had similar problems and had some grould loops on my house, i fixed that and was enough

Ground loops should not be able to generate magnetic fields that induce fatal currents into typical laser diodes. And by ground i'll just include mains neutral since that is only connected to actual ground at one point typically, but only swings up to a few dozen volts if drawing maximum current from sockets.

Static electricity is something entirely different, it is a charge that can build up if you wear insulating footwear or have well insulating ground surface, mostly if you have both (slide around the nylon carpet in wool socks and such).

It is very manageable though. If you have problems with static electricty (mostly in dry climates and such) you should do you work on a somewhat conductive mat. Some people prefer to use a wrist-wrap connected to that mat to keep static from building up, but that's mostly not required: just put your hands on the mat before handing anything and it's fine.

There are some caveats to it though, if you use for example a chair on nylon wheels riding along a laminated floor you could build up some charge by just moving about.

Often you'll notice this static buildup though. If conditions are just right you'll probably notice getting little shocks from many things, such as touching your car or even a shopping trolley, faucet or door handle. If that happens you need to take more serious precautions.

Same goes for when you get a zap from touching other people - it can be fun for sure but is also an indicator to be extra cafeful with electronics that will not appreciate the romance at all.

Why are people responding to this 2 1/2 month old thread today? Someone necro post here and get the ball rolling?

coz August is Static month.. time to be careful..

btw while you guys are already here.
Is this OKay
I remove the 'blades' of a HD cord (PC) leaving the round G ground.
so when I 'plug' it in.. its only that one --I attached the Green wire on the other end to my wrist band.
any reason that's bad .. side from doing it during a thunder Storm..

(did anyone mention a ESD protected soldering station?? some have a place on side to attach ESD wrist band or workmat. IIRC)

I have a Weller solder station that has a ground attachment where I ground my mat and wrist strap. I hardly ever use that station any more as I have a temperature controlled one I use all the time now. The Weller stays plugged in though.
