MacroFab currently offers three different classes for orders. The class of service needed will depend on your PCB’s specifications, parts, and quantity of units. Quick Turn Class Service and Prototype Class Service orders are batched together to reduce the NRE and other associative costs across all customers. This however requires a narrow set of design rules and specifications.  With the Production Class Service, the number of PCB specifications you can choose is much wider, but you will have to purchase an entire panel for manufacturing.
