[Elecraft] RE: lead-free solder (plus bonus desoldering primer :)

[Don Wilhelm]

Ron,

Thanks for sharing that link.

The points of most interest to me in that white paper is that our methods of
adding components to a board (especially where we cannot place the component
onto a properly plated pad - i.e, a trace scraped cleared of solder masking)
are at greater risk for vibration and aging failure when bonded with
lead-free solder.

73,
Don W3FPR
