Many different methods of connecting components have been used over the years. For instance, early electronics often used [[point to point wiring]] with components attached to wooden breadboards to construct circuits. [[Printed circuit board#"Cordwood" construction|Cordwood construction]] and [[wire wrap]] were other methods used. Most modern day electronics now use printed circuit boards made of materials such as [[FR-4|FR4]], or the cheaper (and less hard-wearing) Synthetic Resin Bonded Paper ([[SRBP]], also known as Paxoline/Paxolin (trade marks) and FR2) – characterised by its brown colour. Health and environmental concerns associated with electronics assembly have gained increased attention in recent years, especially for products destined to go to European markets.

Electrical components are generally mounted in the following ways:
* [[Through-hole]] (sometimes referred to as 'Pin-Through-Hole')
* [[Surface mount]]
* [[Chassis mount]]{{clarify|date=September 2023}}
* [[Rack mount]]
* [[Land grid array|LGA]]/[[Ball grid array|BGA]]/[[Pin grid array|PGA]] socket
