Dear all,
I am about to install my subreceiver and would like to finish before the weekend but I have no ESD work place. How can I best protect the parts? Or do I have to wait until I can get the needed ESD equipment?

Wear cotton clothing rather than nylon or highly static material; avoid
walking around on static-prone carpets. Wrap a length of bare copper wire around your wrist and solder a 2 megohm resistor to it. Connect that to a nearby ground connection. Just ensure that the K3 is always at the same potential as yourself by touching its frame regularly. You should be okay at that. 73 de David G4DMP In a recent message, Kjeld Holm <[hidden email]> writes >I am about to install my subreceiver and would like to finish before the >weekend but I have no ESD work place.

Kjeld,
I used a table away from electrical appliances and covered it with tin or aluminum foil. I had an antistatic wrist strap which I connected to this large piece of foil and worked in this manner. Ideally you would connect the foil to a ground through a 1 MegOhm resistor. Note I did not power the K3 or any test equipment up while working atop this foil otherwise one would possibly cause a short or worse electrocute oneself. Generally the larger the area of conductor the less the difficulty with ESD, at component level the risk of ESD damage is greatest, at board level it is considerably reduced and at assembly level it is further reduced. You do the above at your own risk but it worked for me. Wear cotton avoid synthetic clothing and stay away from rugs or carpets. Safety first and I suppose this means we should both purchase an anti-static mat. Good luck and please thinks safety first. 73 Doug EI2CN -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Kjeld Holm Sent: 17 December 2010 09:18 To: 'elecraft' Subject: [Elecraft] K3 ESD Dear all, I am about to install my subreceiver and would like to finish before the weekend but I have no ESD work place.

Wrap a length of bare copper >wire around your wrist and solder a 2 megohm resistor to it. Well, maybe do the soldering first... The resistor can be 1 megohm or anything else in that region. It purpose is to limit any ESD current surge, and also to limit any accidental shock current in your body. For both of those reasons, the resistor should be at least 250V rated, and the wrist band must be insulated from any accidental contact (except to yourself). >Connect >that to a nearby ground connection. Just ensure that the K3 is always >at the same potential as yourself by touching its frame regularly. > NO - that is completely the wrong way around! A "ground" connection to the Mother Planet will NOT ensure ESD protection. If done without proper understanding, it is more likely to *increase* the risks to both the equipment and yourself. The whole purpose of ESD protection is to minimize all voltage differences and current surges between your body and the electronic components, so connect your home-made wrist strap directly to the K3. Since you do not have a proper ESD mat, place the K3 and KRX3 on a sheet of aluminium foil. Before opening the anti-static bag containing the KRX3, leave the bag on the foil for a short time to allow any static potentials to equalize. You will then be working with a reasonable level of ESD protection. As it isn't necessary to connect any other mains-powered equipment or use a soldering iron while installing K3 option boards, grounding of the K3 and the sheet of foil is purely optional. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I also put *everything* on a metal tea tray which has the Mohm resistor to
earth. My wrist strap connects to the tea tray. Equi-potential is the secret. Put the unwrapped packets on the tray with the K3 and unwrap them onto the tray.

Hello, Kjeld...
I have done lots of work with electrostatic-sensitive components for a number of years, and have never had anything wrt ESD other than a wrist-strap (and its IMPORTANT series resistor). I rarely use the wrist-strap, but instead try to use common sense wrt grounding... I use a grounded soldering station, which in your case of the K3+subreceiver is irrelevant, and am careful to discharge myself on one or more grounded devices AFTER seating myself to work on the electronics. I habitually to wear cotton or wool clothing, not plastic (synthetic) cloth. Even if the devices on which you "ground" yourself are not physically grounded, if they are large enough their capacitance will accept enough charge to equalize potential differences in the surroundings and render you non-dangerous wrt ESD. (After all, a "ground" is really a connection to a rather large conducting sphere called "the earth.") In the USA most devices such as computers, some lamps, etc. have a 3rd wire connection to ground and make good discharge devices. One simply wants to minimize the potential difference between you, your work object, your soldering iron, and your coffee cup. Great anxiety is not necessary.

Kjeld,
Go to the store and purchase a spray can of Static Guard - or by whatever name it is in your country. It is the product that the ladies would use to keep their static charged garments from clinging. Spray that on your clothing, chair and work area. The improvised wrist strap that others have suggested is also a good idea - be certain to add the resistor for your safety. 73, Don W3FPR On 12/17/2010 4:18 AM, Kjeld Holm wrote: > Dear all, > > I am about to install my subreceiver and would like to finish before the > weekend but I have no ESD work place.

I've mentioned this idea before but I like it so much I'll repeat it:
I attached a metal yardstick (meter stick) to the front of my workbench and connected it to ground through a 1 meg resistor. My arms naturally fall on it, and it is invaluable when building kits and cutting wire to length. I have an aluminum muffin tin for holding parts which is also connected to ground via a resistor. I use a wrist strap and mat too, but I suspect the ruler would be enough by itself.

NO no no ... you don't want to connect yourself to ground. You want to connect yourself to whatever semi-conducting surface you are working on (the one that the K3 and it's components are resting on). Connecting yourself to ground merely increases the chance that there will be a potential between you and the rig. I simply laid out a large enough amount of aluminum foil to hold everything, wrapped a bare wire around my arm just above my elbow, and used a clip lead to connect the bare wire to the aluminum foil. I know everyone recommends a large value resistor be placed in series with the bare wire for safety reasons, but I did all this on a large wooden table several feet away from anything else and skin resistance here in dry Arizona is fairly high anyway.

I was 12 years old... I think it was a Heathkit HW ???
I woke up early ready to sling solder. My bed was next to my "shack/workbench". The parents and sister were all sleeping... Then it happened... A large blob of solder slipped off the iron onto Mr Happy! (My new best friend) Shrieking and shouting... the blob "stuck". The noise from my room awakened Sister and her sleepover friend. (The one I had the sweets for.) They stormed into my room followed by Mom and Dad. Sisters friend was first into the room causing her to squeal as she tried to turn around and run out of the door she just came into. Thereby running into Sis and parents. The solder was still stuck and still hot. By parents wanted to call the Doctor...but I had enough humiliation for one day so my Mom gave me the ointment and that was that. Durring breakfast no one said anything about the early morning "event". ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Proper electrostatic mats are cheap and readily available. A local
electronics shop in Seattle sells 3x4 foot sheets of the material for about $30, and they tend to charge higher prices since they are the only local source for electronic components. Also, Radio Shack sells a folding plastic model complete with wrist strap, resistor and clip. Although some on the reflector question whether the Radio Shack model is sufficiently competent for the task, I have had mine for many years and built a K2 and K3 on it with no problems, and for some of it I was working over carpet. Why pay so much for a high quality radio and then scrimp on the anti static mat? -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Vic K2VCO Sent: Friday, December 17, 2010 8:51 AM To: [hidden email] Subject: Re: [Elecraft] K3 ESD I've mentioned this idea before but I like it so much I'll repeat it: I attached a metal yardstick (meter stick) to the front of my workbench and connected it to ground through a 1 meg resistor.
