Project 3

AAswin K15 Sept 2022

AIM:-

Creating a workspace for Ethernet shield in altium
Defining a PCB board size using the DXF data provided
PCB clearance to be set as 0.15mm and track width to be 0.2mm for power line and 0.15mm for rest of the circuit
Following the image and BOM provided for creating the schematic and find the datasheet from online for creating the footprint and symbol.
Use Saturn PCB tool to find the values for 100ohm impedance for the high speed differential pair signals and via current calculation
Set PCB to 2 layers. Follow the stackup advised on the course module
Identifying the key points to consider for PCB design using the datasheet
Assemble and route the components as recommended by the datasheet
Place the components on top sides of the PCB and tracking on both sides. Use the image as reference to place the components
Add 4 fiducials as per the image provided diagonally opposite
PCB board with the text (“Ethernet Shield”)
Generate 3D files for all the components and a 3D view.
Generate PCB panel of 150mm x 150mm and place as many circuits as possible and follow routed method v-scoring
Generate complete output files for DFM and DFA (Gerber, Altium draftsman, X Y data, BOM, assembly diagram, fabrication diagram, PDF’s)

Ethernet shield

Shematic

Creating a workspace for Ethernet shield in altium

STEP 1 CREAT A NEW PROJECT

GIVE NAME

step 2 creat a new schematic library and add name Ethernet

next we need to add fiducials and mounting holes

Fiducials and mounting hole:-

Grid settings:-

cloud storage result:-

Defining a PCB board size using the DXF data provided

we need make required board line and circuit foot with the help of rules

example.

Here i tried PQFN

64 PIN

BOARD OUTLINE GIVEN :-

iam gointo design and take rule section

from that all rule give required values and etc...

Routing:-

Finally, we are getting to the part - routing. it’s always exciting to see rapid progress and a project get closer to completion.

Altium has some fantastic tools that make routing very easy. The Interactive Routing tool is what you’ll most often use for routing. You can get started by pressing Ctrl + W or going to Route → Interactive Routing.

Copper Pours (Polygons)

We’re going to add a complete top and bottom copper pour connected to the GND net. This is important for the charger IC's thermal performance, having a copper area to act as a heat sink.

FOLLOWING THE STEP

Thermal relief

Altium PCB design has option to assign the number of thermal spokes as required and has option for the size of the thermal spokes which can also be rotated.

Thermal relief can be applied to specific pin specific net or a components.

it should be direct connection
