I have a copy of IPC-A-610, and PC-2221A, but neither gives me the
answer I'm looking for at the moment. Soldering leaded components is
(usually) done bottomside; is it verboten to do topside soldering so as
to avoid clinching leads? I find it much harder to replace components
when clinched. I know electrolytics it can't be avoided for, and mono
caps probably shouldn't be topside soldered (they change color nicely);
but for resistors with nice long lead spans, is it a problem? [8.1.11
in IPC-2221A] I'm talking hand assembled boards, long-ish life (a few
years) but not space/life support/high temp/low temp/high speed designs
(test equipment).
