In Reply to: Solder joints as diode junctions? posted by Will R on July 1, 1999 at 16:37:57:
Not normally, but if the solder joint is a 'cold' joint, that is, the flux was not all burned off, the joint was moved while it cooled, the surfaces to be soldered sere not cleaned of dirt or tarnish, etc.It should be noted that solder only has about 10-12% the conductivity of a copper wire, and the silver solders are a little more conductive than the tin/lead solders. This is the reason that a good mechanical joint should be made fisrt, so that a lot of the two metals to be joined are in close proximity to each other, this minimizes the deleterious effects of the low conductivity of the solder.
