Mobile Phone Repairing Testing Methods. How To Use A Digital Multimeter. Digital Multimeter Guide and Tutorial with Instructions on How to Use a Digital Multi Meter The meter used for checking various functions related to electric and electronics is called multi meter or Multimeter.

A Multimeter can be used as volt meter, Ohm meter and ampere meter. Multimeter is a very useful instrument which can also be used for checking various electronic components like diode, transistor resistance etc. It can also be used for checking continuity, volt, ohm and ampere. Digital Multimeter Basics Rating and reading of all functions of a Multimeter are displayed on the display screen in digital form which are more accurate and can be easily read by users. Composition of a Digital Multimeter A digital Multimeter can be divided into two parts on the basis of its external features: Digital Multimeter Let us now discuss these sections in some more detail: How to Use a Digital Multimeter?

Any mobile phone PCB has several IC or Integrated Circuit.

These are SMD or Surface Mount Electronic Components. Before understanding how to count legs or pins of any IC, let us learn about IC. What is an IC? An IC is an electronic component made up of combination or integration of several other electronic components like resistor, capacitor, coil, diode, transistor etc. How Many Types of IC are There? There are mainly 2 types of ICs: Leg-Type IC: This type of IC has legs or pins. How to Count Legs or Pins of Leg-Type IC? Counting of leg-type IC starts in Numerical Digit in Anticlockwise Direction starting from the Nose Point or Cut Point. How to Count Legs or Pins of Leg-Type IC How to Count Balls of Ball-Type IC?

Counting of Ball-type IC is done in Both Clockwise and Anti-Clockwise Direction. NOTE: When counting Columns, “I” and “O” are omitted because they look like “1” and “0”.

By Santosh Das | Mobile Cell Phone Repairing. When learning how to repair a mobile cell phone, it is important to learn how to identify parts and components on the PCB of a mobile cell phone.

Identification of these parts and components is not that difficult. The PCB of any mobile phone of any brand namely Nokia, Samsung, Motorola, China Mobile Phones etc is divided into 2 Parts namely: (1) Network Section; and (2) Power Section. When identifying parts, electronic components and ICs on the PCB of a mobile cell phone, it is important to keep these two sections in mind. How to Identify Parts and Components on the PCB of a Mobile Cell Phone: Antenna Point: The point where antenna is connected is called antenna point. Network Section: The section below antenna point and above power section is called network section. Antenna Switch: It is found in the network section.
