Sierra Circuits supports IPC-2581.
Unlock the full potential of your PCB assembly with the industry-recognized IPC-2581 standard. IPC-2581 is a pivotal standard for the exchange of data in circuit board manufacturing. This open, vendor-neutral XML format streamlines communication, ensuring clarity and precision in design data transfer. From layer stack-up to drill details, IPC-2581 simplifies the entire process, fostering collaboration and reducing the likelihood of errors during data transfer. By adhering to this standard, Sierra Circuits enhances the efficiency and accuracy of PCB production, offering a seamless integration from design to assembly. Join us in embracing IPC-2581 for a future-ready and streamlined manufacturing experience.
