PCB manufacturers openly share their manufacturing profile limitations and production capabilities. As a hardware designer, this information is pivotal in aligning our design with these boundaries and ensuring successful production.
However, here’s a thought 🤔. The process of designing differential pair parameters like impedance can be a complicated dance, especially when you’re searching for the PCB stack-up parameters, dimensions, and other physical details.
In most of the designs, we are dancing around the standard:
1️⃣ 85 Ohm,
2️⃣ 90 Ohm, and
3️⃣ 100 Ohm differential pairs.

Imagine if PCB manufacturers provided us with verified parameters for these standard differential impedance values. It would eliminate the stress of parameter search and save valuable time in the design process. In turn, it would also streamline their production process and minimize errors. 💡⏱️🚀
So, dear PCB manufacturers, can we make this a standard? Can we work towards a future where this vital information is readily available, making the design process smoother and more efficient?
