An enormous amount of information is needed to precisely and unambiguously define all of the fabrication details for a PCB and ensure that it is manufactured, tested, qualified and delivered exactly as the customer specified. Widely reported recently has been the development of a new open standard for exchanging printed circuit fabrication data by an independent international task group with members from the entire supply chain. Initiated by Norway-based Elmatica, the CircuitData standard is designed to enhance your Gerber, ODB++ and IPC-2581 files, and not replace them.
Freedom CAD has been designing and fabricating boards with embedded technology for years, and doing some pretty innovative work along the way. I asked Scott McCurdy, Freedom CAD’s director of sales and marketing, to share some details about their embedded processes, as well as the challenges and opportunities that embedded technology offers.

CAD engineers take a CAD file that defines a single part and panelize the data by creating a nested pattern repeated across the panel. Reverse nesting and off-angle part placement may optimize material utilization, which is a constant...
One major issue with understanding the information on data sheets and making appropriate comparisons is the test method category. It is possible to test the same piece of material for dielectric constant (Dk) using two different test...
