Production Minimums
Below is a set of guidelines for data design to follow when it
comes to layout. Not all circuit boards are alike, so not all
designs fit into all production facilities. For these reasons, we
have created a top-notch supply chain to produce all your heavy
copper PCB requirements. Following these rules will allow for
manufacturing to produce your PCB with a standard process setting,
decrease time to produce, and minimize fallout.
