Small Parts / Electronic Components of Mobile Phone: Identification, Faults, Function.
The PCB of a mobile cell phone has several small parts or electronic components. When larning mobile repairing, it is important to learn and understand how to identity these small parts or electronic components and understand their function. Identification of these small parts on the PCB of a mobile phone is easy if you know and understand some of the basic rules. It is also important to understand what to do if any of these small components is faulty.
Most of these electronic components are SMD (Surface Mount Devices). They don’t have any leads like thru-hole electronic components .

Small Parts / Electronic Components of a Mobile Phone: Identification, Faults and Function:
1. Boost Coil
Its size is little bigger than coil. It is found in black colour and looks like a large button. Its function is to increase current. If this coil gets damaged then it has to be changed.

2. Coil
It is found in any section of a mobile phone. It is found in many shapes and sizes.Coils are found in 2 colours: (i) Black and white; and (ii) Blue and white. It has binding of copper coil inside. It filters and decreases Current and Voltage.
Mobile Phone Coil
3. Capacitor
3 types of capacitors are found in a mobile cell phone:
Non-Electrolytic Capacitor: It is found in any section of a mobile phone. Its height is little more than chip resistance. It can be of gray, yellow or brown in color. It has no Positive (+) or Negative (–) side. It filters DC current.
Electrolytic Capacitor: It is found in any section of a mobile phone. Its size is larger than non-electrolytic capacitor. It is found in 2 colors – (i) Orange with brown strip: and (ii) Black with white strip. The side with the strip is Positive (+) and the other side is Negative (–). It filters and stores current.
Network Capacitor: It is found in any section of a mobile phone. It is made from 2 or more Non-Electrolytic Capacitors.
