    Understanding Printed Circuit Board Manufacturing: Working with Duroid laminates

    To begin, the laminate manufacturer freely admits the material will move, but only during the etching process.

    The key they state is to first etch 80% of the copper, cure the material in an oven, then provide a final etch and a final baking cure.

    When beginning work with a new material, you try to do as much research and get as much advice as possible.

    You download the manufacturers documentation and talk with the manufacturers representatives, drill/router bit manufacturers and other PCB manufacturers who have worked on the material in the past.

    After compiling all this information, a manufacturing process is developed which fits both the material and your own facility.

     

    Understanding Printed Circuit Board Manufacturing: Panelization

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

    PCB Manufacturer = The company that manufactures blank PCBs for you, Omni Circuit Boards Ltd is a "PCB Manufacturer"

    PCBA Manufacturer = The company that manufactures an assembled or populated PCB for you, also known as CMs or contract manufacturers.
