Wafer Connector vs FFC/FPC Connector: Selecting for Vibration and Service Access

Wafer Connector vs FFC/FPC Connector: Selecting for Vibration and Service Access A connector can fit the PCB footprint yet be difficult to release after the enclosure is assembled. A flat cable can fit a narrow gap yet load its connector when the cover moves; a discrete-wire harness can pull on a locked housing if its […]

Wafer Connectors: A Practical Guide to Board-to-Wire Applications

Wafer Connectors: A Practical Guide to Board-to-Wire Applications A board-to-wire connector can match the measured pitch and circuit count yet still be wrong for the harness. The missing information may be the mating housing, contact geometry, terminal retention feature or wire insulation diameter. A pitch-only purchase request leaves those decisions to assumptions, which can lead […]

PCB Header Coplanarity and Solder Reliability in Automated Assembly

PCB Header Coplanarity and Solder Reliability in Automated Assembly An open solder joint at the end of a header row does not, by itself, prove that the connector arrived with bent leads. A lifted termination, a bowed PCB, an uneven paste deposit or tilted placement can produce a similar result. Raising the reflow temperature before […]

PCB Header Current Rating: Why Temperature Rise Matters More Than the Datasheet Number

PCB Header Current Rating: Why Temperature Rise Matters More Than the Datasheet Number A header that appears adequate on a bill of materials may still need a lower current in a crowded, enclosed PCB assembly. The purchasing question is not just whether the catalogue number exceeds the load; it is whether that number represents the […]

Terminal Block Enclosure Design: Clearance, Creepage and Wire Entry Considerations

Terminal Block Enclosure Design: Clearance, Creepage and Wire Entry Considerations A terminal block may fit inside an enclosure while leaving too little room for the installed wires, adjacent metalwork or service tools. Terminal pitch alone does not show the shortest insulation path after conductors are prepared, restraints are fitted and the cover is closed. That […]

Pin Header vs Socket Header: When Each Board Connection Makes Sense

Pin Header vs Socket Header: When Each Board Connection Makes Sense Decide which board carries pins and which carries sockets from wear, exposure and service logic, not habit. The pair works as one interface, so specify both halves together. Contents Part 1. What distinguishes a pin header from a socket header? Part 2. Which side […]
