I have a four layer board that requires controlled impedance fabrication for a coplanar differential pair (msata and mpcie traces). My current fab has these capabilities…
Can AISLER do this kind of fabrication? I’m having trouble find the options when trying to submit the board for fabrication on the website. Thanks!
Hi 
welcome to our community. Please note that the response time is delayed during our Christmas break.
First and foremost, I wanted to thank you for your interest in our products.
We also support a controlled Stackup for our 4 and 6 layer PCB’s. You find our Stackup here: 4-Layer HD PCB Stackup
Simply upload your 4 layer design and we will manufacture it using this Stackup.
