2 Layer Medium Run Service
Moving to a small production run? Our medium run service will help bridge the gap between prototypes and a full panel.
Pricing
$1 per square inch, 100 square inch minimum. You can have as many different designs as you want, as long as each design is ordered in a multiple of 10 boards.
For example, if you had two different 5 square inch designs, you could order 10 of each for a total cost of $100.
100 inches is just the minimum order. You can order as much as you’d like beyond that.
Turn Times
Orders will be shipped within 12-21 calendar days of ordering.
Medium Run orders cannot be expedited. For faster fabrications options, you may be interested in our 2 Layer Service or even faster 2 Layer Super Swift Service.
You can get a quote, approve a design, and pay for an order at OSH Park.
