What is Soldering? 4 Solid electrical connection 4 Mechanically connects metal to metal 4 Electronic soldering –soft soldering –350° F
Stuffing the board 4 Before you begin soldering, place your components in the PCB 4 Slightly bend the leads to keep each component in place 4 Start by “stuffing” one type of component (resistors) 4 Once all of that type is stuffed, solder the components to the PCB
Heat-sink 4 Heat-sink clip 4 Alligator clip 4 Place between joint and component 4 You must heat-sink each lead separately
Safety 4 Solder over workbench 4 Put pencil in stand 4 Treat pencil as always hot 4 Always wear Safety Glasses 4 Solder Contains Lead – Wash Hands
