Familiarizing each Now various brands and models of every mobile phone products although   have the same parts but differs on each sizes and technical specs.  Others also are compatible with each other..The Following are the most common  types of spare parts  you can find inside mobile phones handsets.* Battery* Battery Connector* Antenna* LCD* LCD Frame * Camera Module* Plug-in Connector* Flex Cable Wires* Navigator/Joystick/Trackball* Touch Screen Panel * Microphone* Speaker * Buzzer/Ringer* Keypad  Membrane* Simcard Connector* On/Off Switch* Vibrator* Back Housing* Housing BATTERY-A battery is used to provide power supply to the PCB  circuits and  components. There Are various types of Batteries in each particular  mobile phone products, and varies to each sizes and specifications.  Manufacturers coded each particular packaged according to sizes and  where specified product to use. The standard battery Voltage Range is  3.7V and is made of rechargeable Lithium Ion. <img src="http://1.bp.blogspot.com/_8JZhVVmpICU/S975qqImyZI/AAAAAAAAAUg/sfr4Zqv7gCw/s320/battery.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Battery Connectors This the interface where the battery connects and supply the voltage  to  the cellphones main circuitry or PC Board. Old models used 4 pin which  lead to four battery output sources such as +(positive) - (negative) BSI  (battery status indicator)  and Btemp  (Battery Temperature)The latest designs consists of only three pins, The + (positive) -  (negative) and BSI  (battery status indicator) the Btemp is diminished  and still in cellphone circuitry included.<img src="http://4.bp.blogspot.com/_8JZhVVmpICU/S-EVSPYsFoI/AAAAAAAAAUk/Qfz45AEMi78/s320/battery+connectors.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Antenna's  Antennas are used to intercepts and boost network signals, without it  the phone will hardly connects to service providers and results network  signal lost.Antennas also consists of many types and sizes and varieties.  It varies  according to how each manufacturers designs. It is made of thin brass  or stainless metal mounted on a plastic packaging.<img src="http://1.bp.blogspot.com/_8JZhVVmpICU/S-Ea2m31uxI/AAAAAAAAAUs/PIYtwZkMgks/s320/cellphone+antenna.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />LCDLiquid Crystal Display(LCD) is the component that visualize the  operation of a mobile phone handset. It is made of glass with tiny  crystal fixel  that imitate the light source that has programmed to  display certain  information such as text and images.LCD also comes from wide range of specifications older LCD are called  monocrome which only display one certain color. The later designs where  multicolored and displays rich text and images. The higher the fixel  amount on a certain LCD the higher the picture resolution of images can  displays.<img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20parts/cellphoneLCD.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Camera ModuleCamera Modules is the component used to capture and store images, also  comes in different specifications and packaging. Examples of these  modules are shown below. <img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20parts/cellphonecameramodule.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Plug-in ConnectorsPlug in connectors are interfaces used in charging or by charger  plugging, USB and data cables. Various mobile products also have  different plug-in connectors designs.<img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20parts/chargerpluginconnector.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Flex Cable Wires These are wires that is made into a flat thin wires used as an interface  to connect from one circuit or components to another. It  is called  "Flex" means Flexible others also called it a "ribbon wire"<img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20parts/cellphoneflexiblewire.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Joystick and Trackballthis a component parts which is used to navigate certain features on a  mobile phones. It is commonly navigate  "UP","DOWN","LEFT","RIGHT","MENU","ENTER" keys.<img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20parts/cellphonejoysticktrackball.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Touch Screen PanelsTouch screen panels are made of flat thin glass which is designed with  high capacitive or capacitance value. It navigates everywhere on LCD  screen by just using a finger to or a stylus pen to switch trough  certain feature on a mobile phone handsets. <img src="http://i946.photobucket.com/albums/ad302/djniel2k/cellphone%20parts/cellphonetouchscreenpanel.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />MicrophoneA microphone also known as "mouthpiece"is the component used to  intercepts and imitates human voice and sounds to sends to particular  receiver or caller.
