Onward to BatchPCB
Take a look around
www.BatchPCB.com and get
familiar with what they do. They
have lots of stuff to help you. Let’s
put all our Gerber files into a single
zip file that we’ll call
Breadboard_RTC.zip. Click on the
‘Upload New Design,’ then name
the design and upload the zip file.
To use their service, you must
rename some of your files. Rename
…drill.txt to …drill.drl and
… contour.gm1 to …contour.oln.
BatchPCB uploads the files and
shows you an image of each layer;
Figure 23 shows the bottom
They will then provide you with
board statistics. The important one
here is that the board is 4. 25
square inches; they charge by the
square inch which, in this case, will
be $10.62 – not too bad.
They also generate pictures
similar to what we saw in Viewplot.
(Figure 18 shows the bottom
copper layer.) Finally, BatchPCB
generates a picture for you to order
from as shown in Figure 24.
Well, $10.62, plus $10.00 for
handling, plus $5.65 for shipping so
$26.27. I could order more at
$10.62 each and the handling
charge and shipping stay about the
same so each additional one is
proportionally less, but one will do

[BTW — you can get boards
much cheaper from China, but it is
also more complex so we’ll reserve
that option for a later Workshop.]
so it gets sent off quickly, or the first
on the next panel meaning it has to
So, how long will we have to
wait? Tune in next month and find
Now We Wait ...
BatchPCB works — as its name
implies — in batches. That is, it
waits till it has a big enough batch
of boards to fill a PCB panel. It then
gets sent to Gold Phoenix in China
who makes the full panel, then cuts
out all the boards in that batch.
This process takes an unknown
amount of time since your board
might be the last one on the panel
