Our PCB micro-mill is capable of producing dual-layer custom circuit boards using materials such as FR-4 and other circuit board materials.  Typically, we limit activities to providing a bare (copper) board.  Generally speaking, our services are most applicable in cases where a basic prototype is required quickly, and/or your needs are very simple (1-2 layers, no solder resist, only a few vias); other board-manufacturing services (oshpark, seeed studio, etc) are capable of making far more complete, and feature-rich boards at low-cost.  In some cases, we also offer basic PCB design services.
