Hello Martin,

is that 22mins 20 seconds?
Click to expand...
Now imagine this one, true story: We were doing layout in the 80's on a
large mainframe. During the 23rd hour a snow storm was beginning to
brew. It became spooky outside. Then I could see large 100kV lines in
the distance swing back and forth, screamed "backup" and a few minutes
later those same lines touched with an impressive arc. Poof, no more
power. After 2-3 hours the air inside became unbearable and we all went
home. The next afternoon we had power again but the backup files
wouldn't read correctly and we were back to square one :-(

I'm not sure what PADS means by that. It's probably hh:mm, but we have
about 3 weeks in it so far, so maybe it restarts the clock every time
we do a SAVE AS iteration, or something.

What scares me is the 1000+ parts on one board.

That last PCB was laid out twice in a row. It had 1567 smt and 432
thru-hole parts, and from the outset we worked with the mfg to ascertain
the necessary clearances for the leaded component stuffer. My tech spent
almost a month laying oput the PCB, and after it was completed the
contract mfg changed their minds about the required clearances (they
doubled), and he had to re-do the *entire* layout. It took 2-and-a-half
weeks the 2nd time, and we were not happy. The word "fuck" featured
prominently in our discussions.

After that PCB was laid out, they changed their minds again, and we hit
the roof. A site visit showed the problem was a lack of competence on
their part - we showed them what to do and they managed to make it work
- the prototype run of 200 units was perfect.

The hilarious part is they then went on to manufactuer 1000 units, of
which about 400 had piss-poor reflow soldering - esp. around the
TQFP144, the solder paste hadnt reflowed at all. We sent 10 back to be
reworked, and they came back looking like a plasma cutter had been used
to do the job. So I spent 3 weeks hunched over a binocular microscope,
doing it by hand.

needless to say that was the last job they ever did for us, and I take
great delight in spreading the story far and wide (NZ is a small
country). bastards.

Yeah, ain't life grand.

My board is a bit smaller, VME Eurocard at 6.4 x 9.2 inches, but it's
interesting that our equivalent component densities are almost
identical, 0.18 versus 0.20. We have three TSOPs (uP and two Xilinx's)
and jillions of tiny analog things and 0603 parts. It's a 16-channel
isolated-output DAC, basicly. 16 relays, too!

I'm luck to have some *really* good people in-house who assemble
protos and moderate production runs, and we confer with them during
design to make sure they'll be happy building the beasts.

I saw the costed BOM for that PCB yesterday. total parts cost (excl. 121
LEDs) is $8 less than the micro cost in the (non-functioning) design it
replaced. Its 120 copies of the same thing.

ya gotta love SMT :)

I've got 45 SOIC14s, a SOIC8, a TQFP44, lots of 0603s and 1206
quadpacks, a few dozen dual transistors, 121 photodiodes and 120 LEDs.
Oh, and a crystal and a buzzer too :). The layout was a bit tricky
because of the circuit design - 1000x gain on lots of signals that run
all over the PCB, so crosstalk was a problem.

I love my job :)

I especially like laying out analogue circuits (they are "ue" better
than analog circuits ;) in smt, its a real challenge to make basically
single-sided layouts.

thats the smart approach. I like vertical integration, but a good

and are probably more complex.

the 1999-part PCB contains 432 identical LEDs & drivers. Our first build
used about 1.5M leds and 10M smt parts. 3 years later its still going well.

The one I did this morning is 6.5x5mm and has 4 components on it. Just
can't compete. (I bet I'm less competitive than all of you.)

unless you're a minimalist, in which case you're probably more competitive.

Man, you guys do large boards. A couple of minutes ago I checked off on

Most of the ones I do are 75-300 parts.

I'd have been tempted to add one relatively pointless unstuffed

I had the same thought - Find a reason for one more part. Maybe a 0u1 cp or
something.

There are rarely too many test points or ground lugs.
