7 Microscope or Magnifier:

These used to see a magnified view of PCB or electronic components. These are available in different zoom
options like 2X, 3X, 5X, 10X etc. Many microscopes can also be connected to a computer or a monitor.
Because SMD components on a Mobile Phone PCB are very tine, we need a magnification equipment tool or
equipment to see the PCB and Components enlarged. There are Tools and Equipment like Microscope, USB
Microscope, Table Top Magnifying Lamp and Head Magnifier with LED Light.

8 Magnifying Lamp:
It is used to see the magnified view of the PCB of a mobile phone. Most magnifying lamps also have light.
Magnifying lamps are available in different magnification such as 3x, 4x, 5x, 10x, 50x etc.

9 Hot Air Blower:
A hot air blower is also called SMD (Surface Mount Device) rework station and SMD repair system. It has control
to regulate or manage temperature and flow of hot air. Always buy a good quality ESD-Safe hot air blower.

10 Mobile Phone Repairing Tool Kit:
A mobile repair electronic tool kits consists of most of the small tools need for most electronic repairing jobs. Most
such tools consists of soldering iron, desoldering pump, solder wire, desoldering wick, precision screwdrivers,
tweezers etc. So, there is no need to buy all these tools individually.
Concept of different types of IC used in smartphones:
Integrated Circuit or IC is an SMD Electronic Component made up of combination of several transistors, diode,
resistor, capacitors in a tiny semiconductor chip. Integrated Circuit Electronic Components or IC are of small size
and very light weight. They produce excellent results at low power.

Types of Integrated Circuit (IC):
On the basis of external structure, ICs or SMD can be classified as follows:
Single in-line pin package (SIPP).
Dual in-line pin package (DIPP).

Quard pin package (QPP).
Pin Grid Array Package (PGA).
Ball Grid Array Package (BGA).
Leadless Chip Carrier (LCC) Package.

Types of Integrated Circuit (IC) on Basis of Technology:
There are two types of IC on the basis of technology:
Linear IC: This type of IC works on analog signal where output signal varies according to the variable input signal.
Digital IC: This type of IC works on digital signal. A defined output signal is received from a defined input signal.
On the basis of electronic components used, the digital IC are of various types.Examples of Digital IC – CMOS
(Complimentary Metal Oxide Semiconductor), DSP (Digital Signal Processor), DRAM (Dynamic Random Access
Memory), ROM (Read Only Memory), PROM (Programmable Read Only Memory).
Different kind of Application that is used in windows and android:
Application software is a program that developers write in a high-level programming language and install on the
user’s system. For example, Windows Media Player, Adobe Photoshop, Skype, Any Desk, VMWare, and MS
Paint are application software. Users can access the Software as a Service and download installation packages of
other application software from online repositories. Vendors can also pre-install some applications on the system.
Furthermore, installing an Operating System includes incorporated applications like Control Panel, Snipping Tool,
File Explorer, and more.
Users download and install Application Software on their computer system, which requires a system software,
primarily an Operating System. Whether it’s a GUI-based OS or a command-line based, it is the basic necessity
of every application.
