UCLAN..

Another possible solution is after describing exactly what you wish to
be asked, let someone ELSE make the phone call for you.. It would
probably be much more productive than e-mail or a news group combined.
This solution is all based on how important or not this information is
to you..

Good luck!

Cheers,
Mr. Mentor

Honetly I doubt anyone at the support phone number knows or cares if this
VCR has SQPB if Sony support is like every other company.

Wish I could help you, but I don't have that model.

The safer practice nowadays is to use high resistance materials,
and NOT aluminum foil, or metal film covered plastics, or that black
conductive foam. The low resistance materials allow fast and high
charge/discharge currents that can vapourize small tracks or
microcircuitry.

Please show me where this is documented and what family of semi conductors
to which it applies.

My calculations show that the probability of
producing excessive current flow inside a CMOS chip by use of aluminum
foil,
without already having exceeded the voltage limits of the chip, is very
small.

Depending on what you mean by 'correct ip information', yes.

You need to understand what the header of the e-mail message gives you.
The only information that is 'completely trustworthy' is the LAST information
added by YOUR mail server when it is contacted by the server that sends it
the e-mail message.
Older header information could be forged [but is often correct].

A program/service such as samspade can be used to find more information on
the server that sent the e-mail to your mail server.

Yes, but you can not 'have a significant charge' on a chip without

You can certainly have a charge that does not exceed the breakdown
potential of the IC oxide layer yet results in probably several AMPS of
instantaneous current when shorted into close to zero ohms through an
aluminium foil sheet.

Why do you NITWITS feel the need to argue about the BLEEDING OBVIOUS ?

Why do you feel the need to insult someone that is trying to help you

I'm never going to learn anything from a halfwit like YOU.


A half amp is .5 coul/sec. This represents about 3.121 x10^18 electrons.
A penny (1950 vintage) weighs about 3.1 gm and contains about 2.9 x 10^22
atoms.
There are clearly quite a few electrons in that penny, but NOT a huge
excess
of electrons, normally.

You really are FUCKING CLULESS.

Graham

Nice rational argument there Grahm. In my opininon you essentially
discredited everything you have said by resorting to name calling.

After reading everyone's argument, from what I can tell it seems Alunimum
should be fine for most circumstances. Even Sam says it's fine.

To create the anti-static effect, the black or silver bags are

Says NOTHING about high current being a hazard.

It's important to discharge at a slow rate,
http://en.wikipedia.org/wiki/Antistatic_mat

This is for a floor mat, used to discharge the static build up of someone
walking across a room.
It has NO bearing upon your claim that a high CURRENT can be discharged from
a chip causing damage to the chip
WITHOUT the chip having a high static voltage on it to start with.

The World's First Real ESD Safe Foam
Amazing Constant Surface Resistivity 10^6 – 10^7
http://exdron.com/e-p-foamd.htm

sales hype. No documentation claiming that high CURRENT is a hazard in the
absence of a high voltage charge.

http://zotefoams.com/pages/EN/techinfosheets/TIS17.pdf

This MIGHT have some bearing on your claims in that the resistance specs for
'anti static foam' have a range of values, but it gives no other support for
your claims.

http://www.google.com/search?hl=en&rls=en&hs=dxx&q=static+dissipative+foa
m+resistivity&btnG=Search

Useless google search. Show me something that supports your claim, don't send
me on a scavenger hunt.

Now go and take your IGNORANT ideas elsewhere.

I would rather learn than remain ignorant and spread apparently
'superstitious nonsense' as you appear to be doing.

I agree that for some things, such as shipping containers, conductive foam is
better.

But I see absolutely no reason for not wrapping a sheet of aluminum foil
around a chip to protect it [providing care is used in transferring the chip
to the foil], or wrapping foil around some non conductive foam and then
poking chips into the foam through the foil [again, taking care when picking
up the chip and bringing it into contact with the foil].

I think your idea about high current discharge is WRONG, because, as I have
tried to show you with a few calculations, there ain't enough electrons 'in
the chip' to damage the chip due to high current UNLESS the chip has a high
static charge on it already!

Since some chips can be damaged by voltages of 10 volts [ten!], the VOLTAGE
is the hazard, NOT the current.

[quote from esdfunds1print.pdf from
http://www.esda.org/esd_fundamentals.html]
Many electronic components are susceptible to ESD damage at relatively low
voltage levels. Many are susceptible at less than 100 volts and many disk
drive components have sensitivities below 10 volts.
[end quote]

There is quite a bit of interesting stuff on that web site but I see NOTHING
about 'high current discharge' damage due to shorting pins of a chip
together.

Again, I think that is pure nonsense.
If you can support it, I will gladly change my opinion.

If you call me names and curse at me, I will stop reading your posts.

I am only willing to spend my time talking with those that have enough SELF
RESPECT that they can afford to treat others with respect also.

That's absurd, Bob. No top-poster has ever made a reasonable argument in
favor of top-posting. A single reply to a single post, sure, not much
difference. An on-going thread with multiple participants, some of whom
are top-posters, disintegrates into utter chaos. It becomes impossible
to quote accurately and follow who says what. Any top-poster who doesn't
understand that is either pig-headed or a complete moron.

If you remove the metal tape, and not put it back, you can cause
interference internally in the monitor, the computer near to it, with
public service communications in the area, and possibly with other
external devices.

Many of the electronics parts suppliers that supply parts for
communications systems also sell insulated metal shielding tape. You can
also go to a hardware store and buy metal tape, but it must be surface
insulated for safety issues. You don't want such a large area of
conductive metal being exposed in case something touches it, or it
touches the circuit board or other parts.

Whatever metal you use for shielding, it must be properly grounded to
have the effect. If not, it will become an antenna and even worsen the
emitted radiation. In some cases we found the length and width of the
metal to also have an effect on the characteristics of its shielding
effect. This can be seen with a spectrum analyser using an antenna
probe.
