- [Instructor] Now that we've pushed our components
over to the PCB side of things,
let's take a look at placing some of these components.
It's fairly simple and intuitive and all my
navigation tools here are the same as they were
on the schematic side of things.
But really at this point, it's really just click and drag,
and using grids and so on.
You see my main chip here,
so I can just click and drag this.
Notice as I click and drag it I see all of the rats nest
coming along with it, so essentially those are all the
temporary connection points showing
which pin is connecting to which pin and so on.
But I just click and drag to move my component.
And let's say my first couple components that I will
place not on the radial, or polar, grid.
So maybe I'll just turn that off.
So again, I'll jump into my grids here,
and I'm just gonna turn off my polar grid
for a second here, or hide it.
And I'm back just to the Cartesian grid there.
And I'm just gonna try to place this chip
somewhere in the middle, let's say maybe about here.
And it should jump or snap to my specific grid points
so I can get very accurate placements of all my components.
And again, I could just change my grid to be able
to snap in different dimensions and so on.
Just click and drag there to place simple component there.
And right in the middle, let's do a similar thing
with my connector here.
Just click and drag here.
This is a connector here.
But what can also be useful here,
similar to when I was inserting things on the schematic
end of things, I have similar options here.
So as I'm clicking and dragging, or as I'm placing
my components, I can rotate.
So if I'm just hitting the Spacebar here,
I'm just rotating 90 degrees, for example.
I also have that same ability
to flip about the board as well.
So in this case I can hit the L command, these are hot keys
that you can potentially customize as well.
But you can see here I'm just swapping which layer
it may be on, in this case I only have two layers,
right, I have my top layer and my bottom layer.
So if I just hit the L key,
hard to notice at first, but you're seeing it's just
jumping from one layer to the other,
which essentially you can see the colors changing
of my layers there.
And you can see if I had a 10-layer board, seven layer
board, again you just hit L to jump through all the
layers you may need until you're happy with you're
placement of your component.
So let's say for example I wanted to throw this connector
on the bottom layer, just hit L and now I'm placing it
on my bottom layer there.
And so you can see the designator would be on the
other side of the board, so it's coming in as
kind of a metered component here as well.
So we have a bunch of options there to help
place our components at any point on our board
and within any layer, fairly simple as well.
Let's say now if I want to place some
components in the more radial direction.
So I want to turn that grid back on.
So I jump back into my grids here.
I'll grab this polar grid, maybe turn it back on here.
Okay.
And now we can see we can use any of these grid points
to try to place a more radial component.
So let's find one of our connectors here as an example.
And I'm gonna try to place this on other radial points here.
So you can see now it's jumping dead along a radial axis,
which is nice, still snap points works the same
as my Cartesian snaps, but it's about
my polar grid points here.
So in this case, let's say I wanna throw it about here,
and again the Spacebar will rotate about that 90 degrees,
but notice now the 90 degrees is about my polar axes.
Say I wanna place it somewhere about here, perhaps.
And then it's a similar idea really to place
all of your components in a similar fashion.
Just place a few here just real quick just to get started.
But you can see it's quite nice and simple to start to place
all of my components there.
And generally again, this will come with experience,
but you wanna use these rats nests
to guide you a little bit when placing components.
I mean, it makes sense to place components
in certain areas of course, and of course trying to
simplify the rats nest as much as possible,
placing components maybe closer to other components
where they may be connecting to so you won't have to
route traces all over the place in very strange directions
kind of jumping all over the board.
That type of thing, again, that will all just come
with experience within your own board designs there.
So I'm not gonna go through placing
every single component here, it does take a little bit
of time depending of course how many
components you may have.
But you can see it's fairly simple process,
we can just throw in a couple here real quick.
Kind of click and drag, Spacebar to orient L to jump to
specific layers and so on.
