How to Avoid NOISE in Your PCB Designs for Better Signal Integrity

STOP ignoring your ground pins!

When your design includes a high-speed connector (like an M.2 card), proper ground placement is EVERYTHING. Don’t just rely on having “enough” GND pins, be strategic about where you put them. You’ll minimize return loop areas and drastically improve signal integrity by interleaving ground between high-speed signals. Here's why:

🔌 Placing ground pins close to high-speed signals helps control electromagnetic interference (EMI) and crosstalk between adjacent lines. This is key for keeping your signals clean and your board stable.

🔬 Each signal needs a return path. By making sure ground pins are nearby, you reduce the loop area and prevent unwanted interference. Less distance = fewer potential issues.

⚖️ It’s not about how many GND pins you have, but where you place them. Strategic positioning of ground pins among signals can make or break your signal integrity.
