If you get this working, it will be state of the art.
Elon Musk and co might want to speak with you.
You might be invited to give the next Faraday Lecture, etc
"The PowerPAK SO-8 is a leadless package. The end of the lead terminal is exposed copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper tip cannot be guaranteed and is not required to ensure adequate bottom side solder interconnection.Got it, then I have to find another mosfet suitable for iron soldering. Is the Si7456CDP PowerPAK® SO-8 sheathed MOSFET suitable for iron soldering?
No , not stupid. But i hope i can help you to know that what you are doing is not like a starter power supply, and with all respect to you, you sound like a beginner as you are asking about fet soldering. Maybe your teacher is throwing you in too deep i feel. I hope this does not put you off the subject area.What is the reason for this writing? Did I ask something stupid?
[/QUOTE]Thanks so much for your valuable suggestions, unfortunately my school's lab does not have a hot air station so I will have to work with another mosfet.
I have also soldered the LMG1020 and no, it also requires hot air. In fact, it was more difficult than most GaN FET packages.Is hot air required for gate driver LMG1020 0.8x1.2mm WCSP case solder, can it be done with soldering iron tip?
I've never used an oven for any of these LGA/BGA parts. It's only worthwhile if you're doing large batches and can place them very precisely.Yes you need your own wee SMD oven to do little BGAs.
You are right in all of what you say. I am really a beginner to this field and asked quite a lot of beginner questions. As I progressed, I realized that I was in a really difficult project, it seems that it will get harder and many problems will arise as we progress. I'm just trying to strive and learn something.No , not stupid. But i hope i can help you to know that what you are doing is not like a starter power supply, and with all respect to you, you sound like a beginner as you are asking about fet soldering.

The layout will be really critical for you. I do not think a 10MHz power supply is a good place to start building SMPS. Not at all. I feel sorry for you.
Here is my free smps course for you

..but there is nothing in here anywhere near 10MHz switching frequency.
There are virtually no off the shelf power supplies for sale that operate at 10MHz....or anywhere near it.
What sort of input/output capacitors are you going to use?......what will there impedance be at 10MHz?
I hope your teacher has told you of the magnitude of the job that they have offloaded onto you.
Your circuit parasitics are going to mean potentially a lot of debugging for you.
