FAQ

What file formats do you accept?

A single .zip of Gerber RS-274X layers with Excellon drill files, as every major EDA tool exports them. Upload it on this page and the board is measured and quoted in seconds.

Do you support controlled impedance?

Yes, on multilayer boards, for single-ended and differential pairs with a tolerance of ±10%. Please include your stackup requirements in the mechanical layer.

What is your standard turnaround?

Two-layer prototypes are typically built in 2-3 days and multilayers in 3-6 days, then shipped to you with tracking. Every quote is for bare boards at the quantity you pick, and larger quantities lower the price per board.

Can you do PCB assembly (PCBA)?

The instant quote covers bare boards. For assembly, write to queries@cucircuits.com with your BOM and pick-and-place files and we will quote it separately.
