Important tools required for soldering:
Solder, Tweezers, Flux, Isopropyl Alcohol, Solder wick
Kinds of soldering:
→ Wire soldering
→ PCB soldering → Surface mount & Through holes
Steps to do before soldering:
1) Make sure to have all required tools nearby
2) Turn on soldering station (600oF - 700oF)
3) Tin solder tip
Important things:
→ Having enough solder on board (nice volcanic-slope shape),
→ Do not put solder tip too long on board (may damage board and/or electrical component),
→ Use the appropriate solder tips
→ Takes practice and good grip to solder properly
→ Regularly clean the solder tip

Two kinds of flux:
1) Rosin flux: Sticky but allows solder to flow better. Need to be cleaned with IPA properly else old dried flux will "eat" on the board
2) No clean flux: Flux that doesn't need cleaning after usage. Let's solder flow but not as nicely as Rosin flux does
