ATCA Pins

ATCA Pins refer to specific types of alignment and guide pins used in AdvancedTCA (ATCA) systems — a standardized platform defined by the PICMG (PCI Industrial Computer Manufacturers Group) for high-performance, high-availability telecommunications and networking equipment. ATCA (Advanced Telecom Computing Architecture) is commonly used in server, datacom, and telecom applications where modularity, robustness, and serviceability are essential.

ATCA pins are mechanical hardware components, typically press-fit guide or alignment pins, designed to:

• Ensure precise mating of circuit boards (e.g., blades or boards) into backplanes within ATCA chassis.
• Provide repeatable alignment during hot-swapping or servicing.
• Prevent connector damage by absorbing the mechanical guidance role before electrical contacts engage.
