    Understanding PCB Manufacturing: Avoiding File Errors

    At Omni not all PCB files we receive are from seasoned PCB design professionals.

    Designs also come to us from enterprising individuals who can credit their body of knowledge to the results of internet searches. The inspiration for this article came from one such individual.

    Understanding PCB Manufacturing: Panelization

    The purpose of panelization is to secure PCB boards during manufacturing, shipping and assembly processes while making their separation as painless as possible.

    Panelization can be as simple as a rectangular board tab routed with a 100mil (0.100”) space between PCB boards and a 500mil (0.50”) border on four edges. Or, it can be as complex as a panel filled with combination jump v-score / routed rounded polygons.

    Understanding PCB Manufacturing: Working with Duroid laminates

    If you have ever driven in the winter and suddenly lost control for no reason, you probably experienced black ice.

    Understanding PCB Manufacturing: Odd Layer PCB Boards

    Our cookbook of PCB recipes includes an assortment of odd layer PCBs.

    About 8% of PCB boards we are asked to produce are comprised of an odd number of layers. But unless you have a specific requirement, it is usually best to design a multilayer board with an even number of layers. Reducing an even layered board by one layer may seem like a cost-saving move, but from a PCB perspective it is not. It may actually increase the cost as well as lead-time and leave you with a warped PCB board which may not meet your expectations. Let's look at the issues in detail.

    How to Avoid PCB Board Delays in CAM

    CAM (computer-aided manufacturing) is the art of translating a PCB board designer’s creative CAD (computer-aided design) output into information required in our manufacturing processes.

    Our processes require your computer generated files to be converted into phototooling films and drill/router files which will allow us, the printed circuit board manufacturing facility, to produce a custom PCB to your specifications.
