*You can get hot tweezers which are have heating elements in the tips.
These are best for SMD with one solder pad on each end such as
capacitors and resistors.

Hello all,
I am trying to remove and replace several Surface mtd Resistors in an
old FT-100 Transceiver. I managed to remove a defective SMD Diode,
and suspect several of the resistors have drifted over the years, and
probably also need to be replaced. I have tried on those resistors
with the solder iron I have, but its just not fine/precise enough for
this. [unless i get really lucky in my attempts.] [they are about 1mm
x 2mm, pretty small].
Why, trying to save $, dont have enough for a new radio any time
soon. Repairs in a shop would cost me more than a new radio. I am
just hopeing that someone in the club has, or knows someone, better
solder equipment that i could use.
FYI, Before I disassembled it, the radio did recieve, and the VHF
transmitter worked at low power. The replacements I am trying to do
are from internet reports from others who have repaired radios with
the same symptoms on the PA board, so i'm only partially convinced
even this will get it working. but its the best chance I can find.
I'm not really an expert in this.
I have planned to remove and verify that the resistors need
replacement, order the replacements from mouser, and then
install/solder them and re-assemble the radio; with a little luck i'd
then have a HF radio to use. So, Please let me know if someone has
some of this precision soldering equipment that i could use for a
little bit.
