Hello Everyone!! and Welcome back from
Captain Jack
Now we'll be starting with our theory
lectures
so first of all before learning about
the various parts of Proteus
we will get an overview of how the
lectures and what topics the
lectures will cover
first of all what is a PCB?
PCB stands for printed circuit board
a PCB is a thin board made of either
fiberglass, composite epoxy
commonly known as fr4 or any other
laminate material
the board supports and electrically
connects
electrical or electronic components using
conductive tracks
pads etched from sheet layers of
copper
laminated onto layers or between sheet
layers of a non-conductive substrate
now what is the purpose of using PCB.
As we are learning making of PCBs using
Proteus, there are
few considerations that are needed to be followed
so that after the manufacturing of the
desired circuit
we get the output as close to the ideal
simulation
as possible. So here are a few points
that will be studying in the following
lectures
first of all the layers in PCB. In Proteus
we can design up to 16 layer PCBs which
includes
top copper bottom copper and inner layers
so we'll be studying under this the
various copper layers
the silk layers and other layers
Next we will be studying about the
selection of tracks
Now in this we'll be studying about
track width calculations,
track width selections according to
current and device specifications,
default guidelines for power, signal and ground
spacing calculations, electromagnetic interference
in tracks, noise reduction techniques
shielding versus grounding what's the difference in both of these?
we'll be learning this all in selection
of tracks.
Then we'll be studying a via
a via is used
to make an electrical connection between
the layers of multi-layered PCB.
A via is constructed by placing copper pads
on each layer of the PCB and drilling a
hole through them.
As we can see in the image there are
different types of vias
that connect the different layers of
copper.
So in this we'll be studying the theory
of selection of via,
how to choose a via, power dissipation
and implementation of via. After that
we'll be studying the selection of
components.
Now not necessarily in Proteus we need
the components
as per the schematic we may need
something
some components which are not present in
the schematic
so we'll be studying the selection of
component using library,
analysis of footprint, placing of
components,
placing theory of capacitors and other
components,
optimization of space on the board
DRC errors
selection of SMDs then we'll be studying
the finishing touches now the finishing
touches would include
points such as selection of power plane,
selection of ground plane,
adding text boxes and logos as you can
see in the image
now after all the finishing touches
there will be some
key techniques and shortcuts that we will
be learning throughout
the various points that are being
covered
So to stay updated and to
study the various types the that points
that I have covered
now stay tuned with me and let's start
in the next video with the layers in PCB
