So, go to Filter and write

"IsDesignator". Enter. Apply.

Go to PCB inspector ->

Hide.

Go to PCB, clear the selection.

Now, I will split the window,

so we can see PCB and Schematic here.

So I go, click here and we see the Schematic here.

and

check if you have this setting: Tools ->

Cross select mode is Selected.

When you use click to PCB, same, Tools ->

Cross select mode.

So, what is happening,

when I select a component here,

it selects also in PCB.

If I select a component in PCB,

it selects in the schematic, because we are going to use it.

First we will start with this biggest

component in the middle

and we will use a special command

for placing the components.

Click here, click into your PCB, go to Tools ->

Component placement ->

Reposition selected components.

It automatically moves the component which we selected.

And press "L" on your keyboard, you change the layers.

Now, it is on the top.

You would like to have it on the bottom,

So, press "L".

And I will place it somewhere here.

In case you can't see some of these windows; for example, Filter, Inspector

you will find them here.

Click on the PCB

Here is PCB inspector, PCB filter,

so you can always switch them on there.

and for placement, we will use

grid, which is like,

0.1 millimeter.

Now, we can continue with other components.

Just to make it nicer, I will switch off this nets:

View -> Connections -> Hide all.

And, to make the placement

a little bit easier,

I will make a shortcut here,

for the placement.

It's Component placement -> Reposition selected components

I will place the button here.

Okay

Start with these 2 components.

Click, SHIFT, click.

Hold the SHIFT down and then click.

Go to PCB.

Reposition selected components, "L"

"L"

And here is one thing, which we are going to fix.

As you can see when I place components, very close to each other,

there is error again, they are green.

So there is a rule,

Design rules ->

Component clearance

which we will set to be 0.1 again.

Okay

Now, we can go closer.

The same for the other side.

Click, press SHIFT, hold it down,

click, you can release the SHIFT,

click to PCB,

Reposition selected components, "L".

"L"

Press SPACE BAR and rotate the component.

Next, this three

Hold SHIFT down.

Click to PCB.

"L"

It will go here.

This one will go here.

This one here.

This one goes here.

Okay.

Now, let's have a look on this divider.

It will be here.

You see, FB1 goes there.

Okay

Here is the other divider.

The pull-ups.

Temporarily, I will place them here.

Just to see how much space we need.

These two pull ups.

Now, this power

part

I will just select this.

It goes to pin number 6.

Here is the pin number 6.

You can see, when I hold cursor on a pin,

it will make the white outline, so I see where it is connected.

And pin 19.

It's here.

There are some other resistors close to the pin 19.

This one and this one.

Okay

This capacitor close to the pin 3,

here is pin 3,

and pin 7.

Good.

On the top we will place

the transistors, inductors and big capacitors.

Let's have a look where the transistor is connected.

Okay, so this one should go somewhere here.

This other one

will go somewhere here,

inductor,

here,

capacitor,

perfect.

It actually remembers the order when you are selecting more components.

So it's very useful.

This capacitor needs to go close to

input voltage here and also

this way.

Don't worry that it doesn't look nice, now.

We will be doing some optimization,

and,

almost done !

Almost DONE!

These two

we missed this component,

which one it is?

We can go here, click here,

and select the pin,

and it will

select the pin, it's this one.

It will go temporarily somewhere here.

Good.

To make it more comfortable,

to work with your PCB,

we will create layer sets.

Layer set is kind of view,

where you enable just some layers,

which you would like to see.

For example, for top layer,

we would like to see only the layer, where is the copper,

and layer, where is the outline around the components.

So when you look on your PCB, basically, the white color around the components.

Here, in our PCB,

it is this yellow.

The copper is the red one.

So I click here, this is the place where you can set it.

LS, board layer set.

New set.

Empty.

Top.

I will enable top layer and top overlay.

I will create also bottom,

layer set.

bottom layer, bottom overlay.

And top and bottom.

Top and bottom.

All these four.

Close.

What happened, now, when you click on this small button LS.

See, here are the layer sets, which we have just created.

When I select top.

I see only the top layer,

and the component outline.

When I click on the bottom,

I see only the bottom layer and the component outline.

Top and bottom.

Placement is very important.

So what I will do, I will drag and drop

this PCB and we have now

big window, so we can see it.

I will disable these dots

from the grid, do you know how to do it?

Do you remember?

Snap, grids, do not draw, do not draw,

I will go on the bottom layer and this is

the place where we will start.

What I will also use is

go with your cursor on a net,

for example this one.

Press CTRL, hold it down and click.

It will highlight the net,

where the cursor was

located or placed.

When you press "[" "]", you can change the intensity.

This is what I will be using quite a lot.

and because the proper placement may take some time,

I will try to do it as fast as possible.

I will start here.

This goes here, this goes here, here, here.

Ground.

This one. This big capacitor I will place somewhere here.

I will leave space going with this 5V

Here

And

Good

This is the way to do, to see how

good the placement is,

or how close the placement is

select all of them and see.

Now, it looks like it's in the middle.

Good, let's check this line.

We can go closer.

Okay

This one can go here,

with this one we can go here.

Good

Here ground.

We need to place the LDO.

Here this capacitor.

So this pin goes here, this pin goes here.

This one goes here.

This has to go here.

This goes here and there.

Okay

Okay

I will move this a little bit here,

and what I will do

I will actually place

these resistors better way.

I can connect these together.

This one

we can connect also these together.

This will need to go this way, this will need to go this way.

Do you understand what I am doing?

I can imagine how I will do the layout.

From here I will go here.

From here I will go here.

Then, somehow this way connect it here.

Okay, this one goes here so

again

with these I can go somewhere here.

This one we place here.

Good

This one is ground, this one I can place anywhere.

This one I need to place here.

Okay, good.

Just double checking.

Before we actually start drawing the tracks,

doing the layout,

we will set up some basic rules for the layout.

These rules are specified by capability of your PCB manufacturer.

So one of the things,

which you need to check with your PCB manufacturer

is what is the minimum clearance.

It is the space between two tracks.

The isolation.

I will use 0.15.

You need to check what is the minimum width,

what they can make.

Again, I will use 0.15.

For the maximum,

let's say 10 millimeters.

Okay

And now, we can do some preliminary things,

based on

our placement.

Okay

Good

This is just to see, how good the placement is

if we can fit everything correctly.

Okay, I think I see the potential issue, this.

So, we need to move this a little bit further.

Maybe better move it over here.

So we have also space for this one.

And we need some space also for this one.

Again, we need to move

this a little bit.

So we can go

Good.

For this maybe the best will be to have a plane.

We need to connect

a few other things.

This is ground,

to make it more visible, I will assign a color to ground.

Ground, right click.

Change color, I will use dark blue.

Press F5, you can switch on the color of override.

override, or F5, it will disappear.

So for example if you select a color for more nets,

you can switch it off or switch on, F5.

We would like to see it. We would like to see what pads are ground.
