Homebrew PCBs

Greetings to all,

I'm new to the board but eager to learn.

I'm embarking on a rather ambitious project that will probably see me making around 65-70 PCB's when all is said and done.  Most will be simple single sided boards but about 1/4 to 1/3 of them will be double sided.

About half of the components are such that soldering to both sides of the board isn't possible.  I've had a look through the group archives but nothing really caught my eye.  Considering that cost is a large factor in this project, does anyone have any good simple feed through methods.  I've considered just placing pads and vias's adjacent to the holes on either side and using surplus component leads to solve the issue as a last resort.

Any other ideas?

Glad to make everyone's acquaintance,

'Dee' Speirs

Nearby vias are what I do.

One fellow mentioned using thin wire and "stitching" the vias with one long wire thread. He then goes back, solders on both sides and finally snips the interconnections. I found that technique to be a time saver during soldering.

Regards,
Royce

I do something like that.

1) eyelets for vias, takes a bit of space.
2) vias as stitched through wire.  Nasty to line up depending on VIA
size.

a bit more costly, but use 'test point' pins and solder both sides.
And you get a nice place to attach a probe if you like.

I use stitched-through wire, but I de-strand some 22 gauge speaker
wire to get lots of really cheap wire to stitch with.  It's just the
right size for 13 mil holes too :-)
