Melt some metal

Soldering

Why Soldering?

• Build your own components• Fix a broken part• DIY hardware options• You like building/tinkering

Safety First

• Always be careful, you are working with extreme heat

• Soldering irons melt metal• They will melt skin• They get very hot and can start fires• Never leave a soldering iron unattended

Basic Equipment

• Soldering iron• Tips for the iron• Rosin core solder• Well lighted work area• Clean work area

Soldering Iron Types

• Basic on/off• Basic temperature controlled• Digital temperature controlled

(the one I use)

Available Tips

• Conical

• Spade

• Chisel

I most often use the conical tip when building Christmas DIY projects

Optional Equipment

• Tip cleaner• Extra hands• Exhaust fan• Magnifying glass• Panavise

Panavise

• Many models• Great for holding boards• Allow lots of movement

Solder Wire Basics

• Use rosin core• I prefer 60/40 tin/lead solder• Size, I recommend .032 (7 or 8mm)• Roll size– Radio Shack has the small rolls– I usually get 1lb rolls

Soldering Process

• Heat soldering iron• Clean tip• Tin tip• Apply heat and solder to component• Touch soldering iron to one side of pin, touch

solder to the other side of the pin• Allow solder to flow• Remove soldering iron briefly and retouch

Helpful Hints

• Solder most items at about 325° C/620 ° F• Larger items or components with heat sinks

will need higher heat because they dissipate heat well

• Bigger items like triacs, turn the iron up to 400° C/750 ° F

• For triacs it may help to trim the legs to desired length before soldering

Desoldering

• You will have to do this• Desoldering wick• Solder sucker• Desoldering iron• Hot air station

Other Soldering Options

• Soldering SMT components– By hand– Reflow/Skillet– Reflow/Toaster oven

Practice Options

• Commercial solder kits• DIY solder kits
