1 Layer Prototype Service

While we cannot fabricate true single-layer boards, we support single layer designs on our 2 layer fabrication service. The cost, stackup, specs, and turn time are identical to that of the 2 layer service.


Our automated upload service expects all files to contain gerber data for a 2 layer design. This often results in errors when trying to place an order.

In many cases, this issue can be resolved by configuring the design tool to output data for a 2 layer design. If only the manufacturing files are available, this usually requires a few files to be copied and modified. Our Uploading 1 layer boards page has a guide on doing this.


$5 per square inch, which includes three copies of your design. For example, a 2 square inch board would cost $10 and you’d get three copies of your board. You can order as many copies as you want, as long as they’re in multiples of three.

Turn Times

Orders are sent to fabrication daily, and will ship within 10-12 days.

You can get a quote, approve a design, and pay for an order at OSH Park.

For a faster turn time, you may be interested in our Super Swift Service.

Need more than 100 square inches of boards? Our 2 Layer Medium Run Service is a less expensive option for larger orders.
