About this service
Send Gerbers (RS-274X) plus a drill file and we return finished, electrically tested bare boards. Standard stack-up is 1.6 mm FR-4 with 1 oz copper, 6/6 mil minimum track and space, and 0.3 mm minimum drill. Tighter geometry is possible on a per-job basis — send the design and we will tell you before you commit rather than after. Every panel is bare-board tested (flying probe) before it ships. Boards are routed and V-scored to your outline; panelisation for assembly is done free of charge when the same job continues into PCB assembly.

Frequently asked
What files do you need?
Gerber RS-274X for every copper, mask and silkscreen layer, an Excellon drill file, and a board outline. A PDF of the assembly drawing helps but is not required. If you only have the design files (KiCad, Altium, Eagle), say so in the enquiry — we can usually generate the Gerbers ourselves.
Is there a minimum order?
Five pieces per design. Below that the setup dominates the cost and you are better served by our prototyping service.
Can you do impedance control?
On 4-layer boards, yes. Tell us the target impedance and the reference layer in your enquiry and we will confirm the stack-up before starting.
