SURFACE MOUNT TRANSISTOR IN MOBILE PHONE & THEIR FUNCTION

Image
Surface Mount Transistor in Mobile Phone and Their Function Surface Mount Transistor or SMT Transistor is an SMD electronic component  made up of semiconductor material like silicon or germanium. There are 2 types of Surface Mount Transistors: NPN Type PNP Type Terminals of a Transistor There are three terminals of a surface mount transistor or thru-hole transistor: Ammeter (E) – Flows current on receipt of forward bias. Electrons are emitted in NPN transistors whereas PNP transistors emit ‘ holes ’. Collector (C) – The terminal of the transistor which receives the emitted electrons or holes. Collector always works or reverse bias mode. Base (B) – The layer between ammeter and collector is called base. Base displays the property of showing low resistance in ammeter junction forward bias and high in collector junction reverse bias. Facts about Transistor Indicating Character : Q or V, TR Function : Switching, Amplification, Regulating Voltage.

MOBILE PHONE AND THEIR ELECTRONIC COMPONENTS FUNCTIONS

Image
Small Parts / Electronic Components of Mobile Phone and Their  Function                               The PCB of a mobile cell phone has several small parts or electronic components. When LEARNING 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 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 look
