Is this something that would be easy to port to? Anyone know much
about developing for table PCs?
I have just looked into the android OS just a little because I got a
new droid phone.

gschem is a single-threaded application. It runs on one core, no matter how

So there are several use cases for treating copper as non-connecting:

* fuses
* low value inductors
* aerials
* contacts for solder switches (eg SPDT in solder)

I'm trying to solder a 10 pin MSOP chip to a home made circuit board.
The pitch of this chip is just 0.5 mm. We tried using the slightests
of dabs of solder across the pins and then used a heat gun the melt the
solder but now I have a chip

These are incredibly difficult to solder without solder mask, in my
experience. Whenever I've had a design that called for them,

Are pinseq attributes really
required for anything I could possibly do with sub sheet symbols?
I think, only pinlabel is required for those.. to correspond to the
refdes= of the IO pin in the hierarchy sub-sheet.
No numbers required at all? That would be good news.

I plan on providing as much help as I can.
If this results in an installable package that could be placed on a server,
this would be a great step ahead.

I've done 0.5mm pitch TQFP on home-fabbed PCBs with an iron. Heck,
I've done 0.4mm pitch too. It's easy if you know how. Here's how.
You'll need:
pen flux
solder wire
iron with normal-sized chisel or hoof tip (I use chisel)
Procedure:
Pen flux the pads on the PCB and the pins on the QFP

Put a small blob of solder on your iron and just run it down one of
the un-tacked rows of pins. This will solder all the pins and
probably short a few. Add more solder to the iron as needed, but you
don't want to add it all at once.
Works for more coarse pitch, too.
Works for more coarse pitch, too. There's a classic on youtube:
I think the only trick is to make sure your iron's tip is BIG enough
to span three or more pins, so it glides along the top instead of
hitting individual pins.

Flux is the secret... Applying flux is the crucial step to success.

Get yourself some good quality flux, it makes this sort of problem disappear.
I've used Electrolube SMFL (aerosol with dispenser tube) with good
results, but there are many good options. Look for something with

I can't say enough about using flux for soldering.
I often use the no clean flux with a metal tip dispenser.
like mouser 577-SF-01
Although it seems that if you don't want to buy a gallon of liquid
flux your getting a pen, which I dislike over the dispenser. It is a
matter of taste.

IMHO, it works better, if the tip features flat surfaces. The solder
happily flocks to a blob on the flat surface
