Many datasheet connector current ratings are based on test conditions that rarely reflect real-world printed circuit board (PCB) power designs. These values typically represent performance in free air at controlled ambient temperatures, with optimal copper distribution and without the thermal constraints imposed by dense board layouts, enclosures, or altitude. Engineers who apply these ratings directly […]

1.0 mm coax connector supports up to 110 GHz
Hirose has launched a 1.0 mm coaxial connector that complies with the IEEE Std 287 and supports frequencies up to 110 GHz. Featuring a compression-mount center contact, the 1.0mm Series coaxial connector supports varying PCB thicknesses from under 1 mm to several mm — providing greater design flexibility. Eliminating the need for soldering, the 1.0mm […]
Miniature SMT test point for dense PCBs
The New Miniature SMT Test Point from Keystone Electronics Corp. features a symmetrical flat-wire design that supports reliable electrical contact while maintaining a minimal PCB footprint. Manufactured from silver-plated phosphor bronze, it is compatible with lead-free and traditional reflow soldering and supports vacuum or mechanical pick-and-place assembly for high-density PCB testing applications.
Updated screw terminals offer anti-rotation design for dense PCBs
Keystone Electronics has introduced a SEMS screw option for its PCB screw terminals, intended to simplify wire attachment and improve mechanical stability in board-level applications. The addition of a preassembled SEMS screw allows users to secure wire leads, including bare wires, without the twisting that can occur during tightening. The terminals are rated for 15- […]

How to manage EMI at the harness-to-PCB interfaces
Electromagnetic interference (EMI) at harness-to-PCB connections creates one of the biggest challenges in modern electronics design. These interface points act as weak spots where unwanted signals can escape your carefully designed circuits, causing system failures. This FAQ discusses four techniques that work in conjunction: shielded connectors, smart PCB layout, proper grounding, and common-mode chokes. When […]
What are the important standards for compliance with wire harness-to-PCB interfaces that engineers should know?
When connecting cable assemblies to PCBs, you need more than just a physical connection. These interfaces must meet specific industry standards to deliver minimal performance across different applications. Understanding the right standards for your project is necessary when applying to both consumer electronics and aerospace systems. This FAQ discusses the most common standards for the […]
