Paul,
Have you included the Multilayer in the list of layers in the plot?
Right click on the printout name in the PCBPrint Explorer Panel and select
Properties.
Add the Multilayer to the list.
Another possibility is the colour assigned to the Multilayer layer is the
same as the background.
Most of the ICs we use are only rated to 85 deg. C operating range. I'd
hate to troubleshoot a board running 130degC components.

hi
Basically FR4 should run up to 130degC, and your semiconductor can most
I would look at the junction temperature as the limiting factor if push
comes to shove. The operating temperature is more of a rule of thumb. The
130degC really only refers to the board material itself anyway.

Don't forget to move the multilayer to the top of the layer list.

Hi
I have designed Ovenized oscillators operating in the 85 degree C range. At
first we used standard FR4. The boards would turn brown and look as they
were about to fall apart after a year or so. We switched to a high temp
laminate G200 from Allied Signal at that time. The BT epoxy types have a
I've one seen a multilayer pcb technology where they have
water circulating inside the pcb.
Is the problem getting the heat away or
has it to be that hot there ?

Dennis Matt,

next annotate or generate a BOM.

Hi,
I've been monitoring this group for a few months now. An associate has a job
to make some changes to his customer's board, and the customer is using Protel
99SE SP6. Since he's not yet joined the group, he wanted me to post this for
him:
We're still hammering away at a 6-layer board
I have never had the autorouter work for me on anything more than a very
basic 2 sided pcb. Even then, I don't like what it does. I do everything
manually. Perhaps I need some training on how to run it properly

I've previously used the autorouter on a 6/6 4 layer board with out many
problems. When using the autorouter I've always had to spend a lot of time
cleaning up the routes. Since that time, I've stopped using the autorouter.
After I saw how much better I can do by hand, with a little more effort
Evidently I have much better luck with the autorouter than most of you folks
do.
I have used it on boards ranging from 2-sided to 8 layer. I admit that
there are sometimes things it does which baffle me, but I don't get the

Are you starting the board 75% routed? If so, be sure all tracks are
correctly assigned to nets before autorouting and be sure to lock preroutes
if you do not want them altered.
Of course 'locking preroutes' may not give the autorouter enough 'room' to
put in remaining tracks, which leads to

Hi Mike,
Page three of the data sheet at:
http://www.ssec.honeywell.com/microwave/products/AT4610specsheet.pdf
points to the mechanical data at:
http://www.asat.com/library/drawings/mod/dgmj4i.pdf
The mechanical data is quite detailed, and you should be able to develop a
PCB footprint
In my experience the autorouter works well when starting from scratch 2 or 4
layer boards. You have to get the design rules right for the density you are
hoping to accomplish.
I have not had good luck invoking the auto-router to just route a few new
added parts to an existing high density
Harry
MANY THANKS
Mike

Hi Mike,

i think Lloyd's assessment here is pretty spot on
the router prefers an empty board, depending on your level of fussiness
it may not be suitable for your work

B 2. The autorouter finishes, announces that it has completed 87% of the board
B (or something like that), and leaves behind hundreds of design rule
B violations, mainly shorts and clearance violations. Tracks will be on top of
B each other and on top of vias. Vias will be in tooling holes.
Hello,
I am going a bit crazy with ODBC errors. I know this is an old problem
but I can't remember what to do about it. I am running 99SE SP6. Win
