To solder a small PCB I need something that can hold it very tightly, so I can touch it and it won't move.
I tried a lot of tools. First I used this third hand with magnifying glass below. But it can damage the board and is not so good for my things.

Then I tried this PCB cell phone circuit board repair holder kit". Didn't work either.

But the best tool I tried was this PCB holder (sorry, but I can't find an equivalent product in a website writen in English).

This last one is ok, but it's tricky for a very small PCB. Besides, it is a little weak. It moves if I make a little more pressure on it.
Another tool I tried to use was this small bench vise, but it is not so good to hold a PCB.

Any more ideas? Is there any specific tool to hold a small PCB?
