I am not good at soldering. I tried some soldering parts on PCB last time, but failed many times.
So I decided to use PCB production services to save time and money (and health).
This service is a little(or a lot) expensive, but it doesn't matter to me if I not have to smell the flux... :-)
And I'm currently designing a PCB that has two SMPS: 5v and HV.
When I finished it, I'll upload it.
