Electronic components, which are the basic elements of electronic circuits, are typically individually packaged and have two or more lead or metal contacts. The electronic components must be connected to each other to form an electronic circuit having a specific function, such as an amplifier, a radio receiver, an oscillator, etc. One of the common ways of connecting an electronic component is to solder to a printed circuit board. The electronic components may be separate packages (resistors, capacitors, inductors, transistors, diodes, etc.), or groups of various complexities such as integrated circuits (operational amplifiers, exclusion, logic gates, etc.) ).
