CAN Transceiver PCB Review #2
Conversation
There was a problem hiding this comment.
All important nets named ✔️
No 4 point connections ✔️
Short circuit protection where needed ✔️- N/A
No circuit compilation errors ✔️
2-layer board:
No DRC errors ✔️
All SMD parts on one layer ✔️
IR Calculations for high current traces ✔️ - no high current traces
Board is mechanically sound, dimensions are correct and component height does not create mechanical conflicts ✔️
IO ports and connectors double checked such that they are accessible when the board is fully assembled ✔️
No unconnected ground ✔️
Ground pour on top and bottom layers. ❌ missing top layer ground pour
Stitching vias ✔️
Length matching for high speed signals and differential pairs ✔️
Proper filter capacitor placement for MCU layout ✔️ - N/A
- Could shorten top of board reducing length of CAN pair but not required
- Recommend adding teardrops
added the tear drops and left ground off the top layer since the bottom plane already provides us with a low impedance ground since there are no traces routed on the bottom layer breaking things up. |
