Master Soldering: IPC 7711/7721 Rework & Repair 

To add, I've followed your channel for a while now. Learned a lot. ):

I need an electronic map for a voltaic regulator for special Russian armor generators so that the input voltage of 24 volts enters the regulator and exits it to the generator. The generator specification is an armature generator with a speed of 1500 cycles and even a minute and an excitator induction coil with a small resistivity of 5 ohms. ) Go to the card can help you in the simplest electronic map

I have ipc7711/21 8years Experience in flextronics malaysia PCB rework , lifted pad pad rework and SRT machine replace BGA but now i no have job after back to hom from nepal

I carry 7711 & 7721 certs. So, John you are one of these Masters I've heard about but never met. I had thought you were a trainer?

Can you do a video for proper tip maintenance ? Maybe suggestions about tip sizes Great work as always !

Hi Sir John, why you are using a bevel type of soldering tip instead of the chisel as per the IPC?

Hello Master! I've tried to access the pages but don't. I have this desire to learn about this due to the city I live in there is no one doing this at the level and technology you do. I would like to know where else start buying tools and if there's any certification course on line? Thanks and your work I've seen on you tube has no difference from an original from factory. It's amazing. Thank you so much that encourages me.

You're awesome.
