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 […]
