1. Four Major Levels of Electronic Manufacturing
Manufacturing of electronic products is a process that has
multiple levels. Each of the levels is highly crucial. Electronic
devices that are commonly used in regular household work, for
industrial as well as commercial purpose go through a complex
procedure of manufacturing.

2. An electronic manufacturing company has to procure multiple
components for obtaining final product. Each of the devices has
its own characteristic components such as resistors for
controlling the electric currents, components for maintaining
the optimum temperature, voltage control, etc.
Once you have all the components you need; begin the process
of manufacturing. Given below are the different stages of
electronic manufacturing:

3. Circuit Board Manufacturing:
PCB development is the first stage of making any electronic
device. It involves developing a printed circuit board (PCB)
for the electronic device.
These boards are made from a material which is electronically
semi conducting in nature so as to both resist and conduct the
electric flow in equal ratio. These boards are the platform for
other components to be attached to.
They contain patterns of electrically conductive material such
as iron or copper. These patterns define the circuit or route of
current in the device. This stage of manufacturing is very
important and special mechanical instrument are used for this
purpose.

4. Integrating the Components:
Once the PCB development is complete, other components are
attached on the surface of these boards. These electronic
components include diodes, inductors, capacitors, resistors,
transistors, transformers, relays. The metallic circuited pattern
which is drawn over the PCB is what defines the integration
process.
The process of soldering is used for carrying out integration
process of electronic devices. Soldering creates metallic joints
between circuit boards and electronic components. In a
company that offers electronic manufacturing services and
where such manufacturing takes place, automated soldering
machines are used.

5. Casing:
In this phase, what type of casing a particular circuit should
have is decided. Every electronic circuit differs from other in
terms of size, operation and functioning. That is why different
circuits need different casings.
Casing means carefully bolting and enclosing the circuit to
ensure smooth functioning. The case is usually made from
insulating materials like plastic. This is done to provide safety
and protection to the circuits from external harms.

6. Testing:
Testing is the stage which is conducted to ensure that each
and every component manufactured is performing
perfectly. The major operations of the devices are
evaluated for this purpose. The testing involves checking if
the components have been placed at the accurate positions,
exposing the parts to varied temperature and humidity etc.
Testing also checks functioning of components on different
voltage levels and ensures that the product matches with
the specified design. Only after the testing phase, any
electronic product is made available in the market for final
use.
