[neonixie-l] Re: How ICs are made - the inside track...

[gregebert]

1985 was my 'golden year' as well. Started work at TRW doing 2 micron CMOS 
design for the Milstar program. Several of those birds are still in orbit, 
and with several of the ICs I worked on. That old technology sure is rugged.

At some point, the process technology:

   - Doesn't result in further die-area reduction due to limiting factors 
   such as finite bonding-pad (ie, minimum) size
   - Is incapable of running at higher voltages (you cant put 15 volts on a 
   10nm transistor)
   - Becomes too expensive and is no longer offset by higher die-per-wafer


I remember we had special thick-oxide transistors to handle 3.3V on 0.13 
micron (130nm); it could not handle 5V. I'm sure that legacy devices like 
the 741, 555, etc require older process technologies just for 
supply-voltage reasons. I just checked MOSIS (they do small-run IC 
designs), and they use ON-SEMI for 0.7micron fabrication. That was 
state-of-the-art process technology *25 years ago* so it still must be used 
for current production of legacy IC's.

It's hard to wrap your head around all of the IC process technology. 
Smaller generally means faster and more power-efficient, but it also costs 
more and takes longer to produce.  I believe the 741 will celebrate it's 
50th birthday next year, and they're still in production.

Re: [neonixie-l] Re: Interested in B7971

[Michail1 via neonixie-l]

Well, about $350 for the tubes.
The boards aren't worth much at all except for the sockets.  Maybe $10  
each (socket).
 
I have about 25 complete boards.  Have caught the wife trying to throw  
them away several times.  I fear she might succeed some day.

[neonixie-l] Re: How ICs are made - the inside track...

['threeneurons' via neonixie-l]

In 1985, shortly after, I got out of school, they just broke the 1 micron 
barrier. I think wafers were ~5" (~130mm).

>From the few people I've known, that were in the semi business, they change 
"mask sets" for parts routinely, for an existing part. This is due to 
keeping up to the current process (shrinking resolution, and growing wafer 
size, etc). So a 555 made today is not the same 555 made 30 years go, 
Probably not the same one made 2 years ago.

[neonixie-l] my version of nixie tube testing device...

[alb.001 alb.001]

 
  My supply only generates about 320 volts dc, it uses a miniature one turn 100 Kohm variable resistor for current limiting and I put 2 leads with 0.1mm post sockets at the ends to push onto tube leads. Uses as I said either 1 1/2 volt or 3 volts as 1 or two AA or AAA batteries (comes in two versions). Can you guess?  - you may find it at your local thrift store or at a camera show - I buy the whole unit for $1 then take it apart for the high voltage generator.  The "guts"  are also available from some electronics online sources such as Electronic Goldmine. If you have a small plastic box - either a fancy Hammond box or something from the dollar store it is easy to put together.

Hi Phil,

 


 Is your tester anything like 
 this one? I would love to make one, though that isn't what I was asking about!

[neonixie-l] Re: IN-13 Lifespan

['threeneurons' via neonixie-l]

A couple of data points, but by no means statistically significant. I've 
had an IN-13 running in my nixie thermometer (pre-kit) for close to 2 
years, now, 24/7, and it runs and looks like new. One of my TRW buddies has 
a simple "winker", that uses the IN-13. It still glows and winks, but its 
no longer anchored. The glow, grow and shrinks, in the middle, and drifts a 
bit. That tube has been running constantly, for at least 5 years.

These tube tubes may have come from "good" batches, that exceed the 
average. They could just be average. Without taking a survey of a lot of 
tubes, who knows.

If you had been over driving them, the graphs would have been "pegged", 
visually, most of that time. If they were bouncing to the music, then you 
were not over driving them. Maybe you just got some from the wrong end of 
the statistical life curve.

  Sounds like a good excuse for a tube autopsy...


  If you are indeed over-driving the current then you'll be sputtering material 
off the cathode which after a while will have two effects. Firstly there will 
be some gradual darkening of the tube as the material deposits elsewhere. And 
secondly you'll see gross physical erosion of the cathode - you can see a 
similar effect on dekatron cathodes where the glow has been sitting stationary 
for a very long time (usually the zero cathode of the tubes making up the 
higher order decades of a multi-tube counter). Given that you describe a 'tink' 
noise, my guess is that the cathode has eroded to the point where it physically 
broke, perhaps under the thermal stress of being activated. Time for new tubes.


  The Soviet datasheets only promise 1000 hour life for IN-9 - I can't find a 
similar overall guaranteed life specification for IN-13. My experience is that 
they will last much longer than that if not overdriven.


  With regard to the current required to achieve full scale, yes there's 
normally some cathode poisoning which needs to be burned off when you first 
fire up the tubes (worse on IN-9 than IN-13), but then they should settle down 
and operate at the specified sensitivity. The last centimetre or so of the 
cathode is difficult to illuminate even in a well 'oiled' tube - they lose 
linearity at the upper extreme. Best thing to do is not to worry about trying 
to light up this bit.


  Cheers,

Re: [neonixie-l] IN-13 Lifespan

[JohnK]

But, if you get the maths right you can actually mimic the response.
[I have audio and broadcast radio station background btw]
Been here before with this argument of course. So, it is possible to get the 
same indication but that leaves the semantics to deal with.
And there are subtle aspects of the visual persistence of different displays to 
deal with too.

The argument usually revolves around the substitution of standard moving coil 
meters for the correct type. The original spec document is on the web. The 
attenuator that 'must' be used and the standard levels topic gets quite 
interesting. 
[Talking about the way the indicated value on the meter when used in its most 
sensitive setting got used as the way to refer to the actual level, rather than 
the fact that the actual level was higher - I didn't tell that story very well; 
have a look at the specs and the circuit and how the common useage developed.]

[neonixie-l] Re: IN-13 Lifespan

[gregebert]

If the op-amp is running on a +5V supply, the maximum possible current in 
the IN-13 is about 20mA per the schematic.
But if the op-amp runs off the +12V supply, you could get up to 50mA .

I think IN-13's are rated for 4.6mA full-scale, so either way you could be 
overdriving it.

on the other channel did the exact same thing! I've attached pictures of my 
drive and power circuitry -- the signal conditioning circuitry is omitted, 
but I think it unlikely to be relevant. I figure something must be wrong 
with my circuit that is causing early death, but I'm not sure as to what. 
Ideas anyone?

[neonixie-l] Re: Interested in B7971

[chuck richards]

When I built the (16) driver boards for the B-7971 array,
I used the little 4 inch square cards from Radio Shack which have
the 22/44 edge connector.  Built (2) card cages for them.  Each cage
holds (8) cards.  Used 22/44 female edge connectors with wirewrap
pins.

I still have a few original driver boards for b7971. I could try to post a 
photo if anyone interested.

Agree. There is no joy in an un-lit nixie. Build stuff.

Re: [neonixie-l] NL 7094

[Paul Andrews]

I like to have them in clocks, but I like to have a few backups lying around 
too, for when they start to fail. Which reminds me, I need to buy some backups! 
I don't want to give the wrong impression though. It is early days so I only 
have IN14, IN8-2 and Z5900M.
