Electronic – How to solder this tiny QFN chip


I am not very experienced with soldering. I have a basic soldering iron with a new tip, and a third hand.

Last time I tried soldering wires to a ble chip that looked like this, I ruined two chips in the process and gave up. Those were not cheap.

Now I want to solder this QFN chip but I want to have the right tools and skills for the job.

Perhaps I don't even need to solder, all I want is to connect some of the pins of the chip to a bread board. If there is another way to do that without soldering, I would prefer that.

I am a novice in this area. Any help, guidelines or reference to tutorials for beginners would be much appreciated.

I just want to know what is the best way, that is relatively safe (so I won't destroy the chip), to get it on a bread board.

I would suggest to buy a QFN to DIP adapter, something like this.

Then, you can use air reflow or solder with an iron. I solder all 0.5mm pitch components, such as CPLDs or FPGAs with a good soldering iron using a small (thin) tip.

However, it might not fit well into your breadboard since there are two parallel rows on each side. What I usually do is solder DIP female pin headers

on this board and then use wires to connect it to the bread brad.
