Components leads

So now we know from previous lessons what is electricity, how we discover it, and how we control it!!
now as an automation engineer let us dive directly into more details about controlling this magnificent signal.
Like we said before it`s easy to make a current flow in a circuit, but adding loads to your circuit makes you need more calculation to save your loads and for sure your self if you are dealing with AC [Alternative current] which we will discuss in future blogs!
So this is our final classification for electronic components

Components Leads 

•  through-hole components

the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly 

• Surface-mount technology

Surface-mount technology (SMT) is a method for producing

 electronic circuits in which the components are mounted or 

placed directly onto the surface of printed circuit boards (PCBs). 

An electronic device so made is called a surface-mount device (SMD).

Components Leads Examples :

• components with axial leads 

• components with dual leads

• Single-In-Line package(SIL)

• Dual-In-Line packages(DIL)

• Pin Grid Arrays(PGA)

• Ball Grid Arrays

• Leadless components
