I understand that part of it is for structural support, but what else is it for?
In: Technology
Conducting electricity between the boards and/components you want connected to a board or circuit.
Eg. Printed circuit board (PCB) had circuits built into it when they fabricated it. There are bare metal pads or metal plated through holes for surface mount or through hole components.
In the most basic method, you place the component you want connected to the board on the pads or on the metal plated through hole. Then heat the metal pad and the component with a soldering iron and then melt solder onto the two, creating a structural and electrical connection.
