CEN PCBA supports IPC-2581.

Maximize the capabilities of your PCB assembly by leveraging the widely recognized IPC-2581 standard. IPC-2581 stands as a cornerstone in the realm of circuit board manufacturing data exchange. This universally accepted XML format facilitates seamless communication, promoting transparency and accuracy in design data transfer.

From layer stack-up to drill specifics, IPC-2581 simplifies the entire process, fostering collaboration and minimizing errors during data exchange. By aligning with this industry-standard protocol, CEN PCBA elevates the efficiency and precision of PCB production, offering a seamless transition from design to assembly.

Join us in embracing IPC-2581 for a forward-looking, streamlined manufacturing journey, ensuring readiness for the future of electronics manufacturing.
