Soldering Procedures

List of Materials:

1. Using cobar core solder 63/37 (Sn64 Pb37) type with flux core or.... the type of solder makes too much difference. 
The diameter of the wire needs to be small 0.012" to 0.020".

2. The solder wick is either Solder-Wick by Chemtroncs. Or Hex-Wick by Hexacon Electric Co.  

3. Liquid flux for between the wick and silicon. 
The liquid flux defines where the solder will flow.  Don't get the flux anywhere you don't want solder.  

4. Alcohol for cleaning the flux from the fixtures after the soldering. A wood toothpick and cotton swab is useful to rub off some of the remaining flux. 
Also rinse the remaining wick with alcohol as it contains dry flux and looks nicer when its cleaned off.

5. Heaters

6. Fixture to hold heaters and fixtures

7. Hot plate (to achieve 220C)

8. Protective equipment
