Step 3: Putting the components on to the board
As far as soldering goes, be extra careful with transistors, semiconductors and diodes; as they can be damaged by heat. I recommend that you use heat sink clips if you are new to soldering or do not have as much experience.
In the pictures, you can see that I placed the chip into a holder. What this does is it prevents the chip from being accidently damaged during soldering as well the chip can be replaced. Putting different chips in the holder a different sound to be achieved.
For a soldering, look for an iron with a lower wattage and finer tip.
