If no SMD, how to minimize?

[Boki]

Dear All,
I want to run a project, but no SMD support, in a very few
components (<10 ) circuits, which method is good way to minimize it..?

Thank you very much for your information.

Best regards,
Boki.

Size, cost, ease of assembly, parts count, ...?

Design your own ASIC? Got a couple hundred thousand to blow on this?

Seriously, you need to tell us a lot more before we can provide you with any
useful information. What kind of project are you trying to do? Is the lack
of SMD support due to historical reasons (and therefore pretty easy to
change) or something like you'll be building a million widgets a year with
Chinese prison labor (and you want to save money)?

Hello Boki,
if you are a hobbyist making "one offs" and experimenting for
fun, then just knock up what you want using "ugly construction"
or "dead bug" construction. Google those terms for more info.
How small you build your module up to you.

Here are a few links for you to get an idea.
http://users.easystreet.com/w7zoi/bboard.html
http://www.qrp.pops.net/ugly.htm
http://www.wa6otp.com/new.htm
In that last link, you can see how the builder has used
little pieces of stripboard to solder IC sockets on to them.
You can then super glue the strip board with IC socket
to the copper surface.

Have Fun,
John Crighton

Hi Boki,

Besides the "Sauerkraut" assembly of parts into a cluster there is
another technique, more for production: Flex circuits. Place all the
parts on a flex PCB and then roll or fold it up.

That's pretty whacky!

It depends how determined you are. For ultimate miniaturisation, start
with the leggiest component and solder all others directly to it, like
a hardwired ball. Ignore all minimum bend rules. Then try
troubleshooting it!

I find this method really easy.
You just use your x-ray vision, and solder with the glowing beams coming
from your eyes
