Hi all,

I'm making a quick-and-dirty connector/contact that would connect a =20
wire to an existing PCB pad (~3/8" x 1/4").  I've reduced the design =20
to having another small piece of PCB touch the existing PCB pad, and =20
at first I thought I'd wrap a piece of wire around the new PCB (such =20
that the wire would touch the existing pad), but now thinking I can =20
use a pad on the new PCB with a blob of solder on it to touch the =20
existing pad.

Should I worry about oxidation?  IIRC some bulb holders used solder as =20
a contact and that works fine.  This is a non-critical connection.  =20
Otherwise, is there a better solder I can use?  Gold plating would not =20
be easy/viable.  This page ( http://en.wikipedia.org/wiki/Solder ) =20
says that Sn63PbP is used for HASL, but I don't know where I can find =20
this in wire form or low volume.

Alternatively, I can put a couple holes on the new PCB and solder a =20
solid wire across it, such that that solid wire would be the contact.  =20
But a blob of solder would be much easier, and I need to make a few =20
dozen of these.

I need the blob of solder, wire, or other to be about 0.01" to 0.03" =20
thick, and I can't find any test-points low-profile enough.

Any other thoughts?

Cheers,
-Neil.
