The SMD technique I've had a lot of success with... my secret
ingredient... is... masking tape!
Be very careful using any kind of tape around electronics.
When you remove it, there is a high likelihood of static electricity
build up. Not likely to hurt a resistor or capacitor; could be very
I'm still pretty new to surface mount soldering, but I'm discovering
that I really enjoy it! Last night, I was building a tiny little
oscillator, just for the SMD soldering practice, and I discovered a
spot where I needed a 1K resistor, but didn't have room for a big
1206 resistor... so I found an

The other tool I use a lot is a pair of bent-nose locking tweezers
that I got from Micro-Mark. They're actually to big for any of the
really tiny parts, but in a lot of cases I can use them to clamp down
a SMD resistor
Have a look at the SMD Doofus on Jim Larsen's (AL7FS) web site. This
is an easy to make tool for holding surface mount devices in place while
soldering. Several different pictures on the page show the doofus in
use while working on a SMD kit. The version I built, shown on the web
site,
being able to burn some solder and get er done. Who
would have thought? !!!

That's my way of doing it. Use good solder wick to get the pad as
free from solder as possible. There is enough solder on the SMD
component pads for it to stick. Then solder the OTHER pad of the
component, before returning to fully solder the first pad.

Hey Ron,
Another item that really helps SMD/T work and rework
is a flux pencil. Mouser carries them and I'm sure
others.
I use a wood toothpick to hold the parts in place
while soldering.
Think the key to doing good work is taking one's time.
A good flip-down jewelers visor helps as well.
Any videos out there showing nice closeups of simple/safe/inexpensive
techniques to solder SMD? Many (most?) of us have zip experience with the
little buggers.

There are some excellent SMD videos on Youtube. They are what gave me the
confidence to try it myself. Pictures worth 1000 words and all that.

In addition to videos, for $7.50 you can get the NorCal SMD QRP dummy load
kit. There are 44 SMD resisters to solder in. By the time you are done, you
have the experience and confidence to tackle other projects AND a handy
little dummy load.
There is also a lot of useful info in the

That may work for the IC's but it does not work well for individual Rs and

... The flux, Quik Chip, etc are nice but not really necessary
I find the flux is very important -- makes it much easier to solder
with fewer solder bridges.
