Box Header vs Pin Header: When a Shrouded Connector Is Worth It

Box Header vs Pin Header: When a Shrouded Connector Is Worth It A box header is essentially a pin array surrounded by a molded shroud. That extra housing increases footprint and cost, but it can also protect contacts, guide mating, support polarization and provide a latch. The right choice depends less on the electrical schematic […]

Board-to-Board Connector Selection Guide: A Practical Engineering Workflow

Board-to-Board Connector Selection Guide: A Practical Engineering Workflow Choosing a board-to-board (B2B) connector is not simply a matter of matching pitch and pin count. The connector also defines board spacing, assembly tolerance, serviceability, signal integrity, current density and, often, the mechanical architecture of the enclosure. This guide turns those requirements into a practical selection workflow. […]

Connector Housing Materials: PBT vs LCP vs PA9T/PPA vs PPS

Connector Housing Materials: PBT vs LCP vs PA9T/PPA vs PPS The connector housing locates contacts, maintains creepage and clearance, survives soldering and protects the mating interface. Selecting the wrong resin grade can lead to reflow distortion, moisture-related dimensional change, latch fatigue or chemical damage. The most important correction to many material comparisons is this: polymer […]

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 […]
