For those of you who have used the International eyelets, which type
have you used ? ( i.e. flat, funnel or rolled flange ).<<
I have used flat infrequently, but mostly rolled flange. These should not
be NON-plated, as it is virtually impossible for solder to wick under the
rolled head, when swaged tightly in a hole. Also, the PCB should be
solder-plated for same reason.

Also what type of plating. Have you used the solder plated eyelets ?<<
See above. Gold (expensive) wick OK (I got some cheap at a "surplus"
outlet), but "solder-plated" is best for small-quantity ("hobbiest") purposes, I
think

Would using those mean that after setting them I would just have to heat
them with the iron and be done with them ?<<
IF there is re-flowed solder-plate on the PCB, this might work, but only if
there had been some "rosin flux" for the purpose, I suppose like is used for
SMT, painted on before eyelets. If you would not be applying solder-wire at
time of eyelet-heating, the iron-tip would become nasty and "dry" very fast,
and leave a streaky, dirty mess about the tiny eyelet heads! For this kind
of "re-heat soldering" a hot-air gun might be a better idea, but decent use
would require experience and failure until "learned"!!!
