In dense electronic systems, stacking multiple PCBs is often necessary to save space while maintaining high signal count and high-speed data transfer. Using loose wiring or generic connectors increases signal path length, complicates impedance control, and can cause signal integrity issues, timing mismatch, and EMI sensitivity. Board-to-board mezzanine connectors provide a direct connection between stacked PCBs while maintaining controlled electrical performance and mechanical stability.
Board-to-board mezzanine connectors are typically selected early in PCB architecture design because stack height, signal mapping, and mechanical alignment are fixed around them. When a mezzanine connector reaches end-of-life, replacement is not always straightforward. Differences in pitch, mating height, signal routing, or mechanical locking can require PCB redesign.
This is common in industrial computing, telecom, and embedded processing platforms where systems remain deployed for many years. Maintenance teams often require the same connector model to maintain compatibility without redesign or signal requalification.
Delays in sourcing compatible mezzanine connectors can lead to production delays, service downtime, and increased redesign cost.
Maketronics assists global engineering and procurement teams with reliable sourcing of both active and obsolete Board-to-Board Mezzanine Connectors.
A mezzanine connector is a board-to-board connector designed to stack parallel PCBs while maintaining reliable electrical connections and controlled impedance.
They reduce signal path length, improve impedance control, enhance signal integrity, and simplify assembly compared to cable-based interconnections.
They are widely used in embedded computing modules, telecom equipment, industrial controllers, medical electronics, and aerospace systems.
Verify contact pitch, stack height, pin mapping, signal speed rating, mechanical retention, and alignment compatibility with the existing PCB design.
