After a recent post on the GQRP Yahoo group I have been asked by several people about the desoldering tweezers I use for removing SMDs. They plug into a Xytronic LF 1000 solder station. I have several different bit sizes as follows: 2mm, 3mm 5mm, 10mm, 20mm and 30mm. There are more available but these suited my needs.
I have also used the tweezers to remove blown chips, cleaned up the pads and replaced ICs. Would not try that without them!
The best way to describe their use is via the photo gallery below.

Some tips
- Use the tip that is just big enough for the job.
- Work as quick as you can because the tweezers can put a lot of heat into the component.
- A slight twist helps move the SMD off the pads.
- Watch adjacent components as they can be damaged.
- Do not squeeze the tweezers too hard or the removed SMD will ping off into oblivion!
- Practice on duff boards before trying a repair.
- Finally, do not be scared of SMDs, using them can be fun!
