Join Collin Cunningham as he explores the oh-so-tiny world of surface mount electronics. Follow along as he constructs what may be the world's smallest phototheremin all in super-macro detail - plus learn why adhesive poster putty is so darn useful.

You should write a book

Is it just me or did MrEdge9898 copy xDwolfonwizard101 to get likes?

@MrSkinnyBill Solder flux. It helps the solder to flow onto a surface. You can get it in pen form (which is apparently a good way to go, I don't do SMD,) or in a bottle. There is a special compound you use to clean it off, or I think you can just wipe it off.
-
What is that liquid like substance which spreads out from the solder onto the board as you solder? Is that one of the things in the solder or is that colour deterioration on the board due to heat?

@MrEdge9898 D:

I forgot to ask where can I find proto boards from SOT-23 transistors?
-
From learning this video I can now use that protoboard to make a SMD version of the VLF converter circuit if I can find 4 pin oscillator chips in SMD size.
-
Tips:
- do like others have said and "tack solder" the component first. Reheat the solder joint and adjust if needed.
- use a little flux at each joint. Clean up with alcohol.
- apply heat the to BOTH surfaces - the trace and the component.
- use WAY less solder.
I would have tacked soldered one leg of the 555, applied flux to the remaining legs, put a SMALL amount of solder on my iron, and heated each surface of the joints. The solder will flow off the tip perfectly to weld the components.
