Board-to-Board Connector Mating Cycles: Durability and Life Expectancy
Board-to-Board Connector Mating Cycles: Durability and Life Expectancy A mating-cycle rating states how many complete insertions and withdrawals a connector has passed under defined test conditions. It does not guarantee the same life in a dusty service bay, a vibrating vehicle or a misaligned test fixture. The useful engineering question is not simply “How many […]

Server Backplane Connector Selection for Data Center Hardware
Server Backplane Connector Selection for Data Center Hardware A server “backplane connector” can refer to several different interfaces: the drive-facing connector, a high-speed cable connection, a controller-to-backplane board connector, an OCP NIC interface or a power-distribution connector. Treating all of them as generic board-to-board connectors creates electrical and mechanical risk. Each location has a different […]

Mezzanine Connector Selection: Pitch, Stack Height and Alignment
Mezzanine Connector Selection: Pitch, Stack Height and Alignment A mezzanine connector joins two parallel PCBs with a plug and receptacle. It can deliver high circuit density and a repeatable board-to-board distance in a much smaller volume than a conventional 2.54 mm header. That precision creates its own design constraints. Pitch, mated height, capture range, PCB […]

Pin Header Current Rating: Derating, Temperature Rise and Parallel Contacts
Pin Header Current Rating: Derating, Temperature Rise and Parallel Contacts Search results often assign one current value to an entire pitch—such as “3 A per pin for a 2.54 mm header.” That is not a safe design rule. Current rating belongs to a specific mated connector pair under defined test conditions. The female contact, contact […]

High-Speed Board-to-Board Connector Design Guide
High-Speed Board-to-Board Connector Design Guide A connector does not become “high-speed” because it has fine pitch. High-speed performance comes from a controlled contact/ground architecture, a repeatable PCB launch and measured channel data. The correct selection process starts with the interface and channel budget, then evaluates the connector’s S-parameters, pin map, stack height and breakout geometry. […]

Pin Header and Female Header Connectors: A Complete Design Guide
Pin Header and Female Header Connectors: A Complete Design Guide Pin headers and female headers are among the simplest PCB interconnects, but small specification differences can determine whether the final assembly fits, carries the required current and survives repeated service. This guide explains the parameters that belong on a drawing or RFQ: pitch, circuit count, […]
