PCB connector design eliminates tools, creates fast connections
Phoenix Contact introduces the XPC 1.5 connector, the first PCB connector to feature Push-X connection technology. Push-X uses a mousetrap-like design to create fast and tool-free connections for rigid and flexible conductors with or without ferrules. Push-X technology uses a contact spring inside the XPC PCB connector that catches the conductor and holds it securely […]
Flex-circuit-to-PCB connector handles 100 W
Hirose has expanded its miniature hybrid flexible printed circuit (FPC) to a board connector family to simplify mating and provide design flexibility. Combining space savings and a high-power capacity, the BK22 Series connector enables OEMs to reduce the size of portable devices without sacrificing power performance. The BK22 Series connector offers minimized contact resistance that […]
Miniature SMT test point
A miniature SMT test point featuring a symmetrical flat-wire design to test PCBs efficiently and safely is one of many items available in the Keystone Electronics Corp. test points selection. This latest “Mini-pad” version enables high-strength, test point-to-PCB bonding, with a minimal footprint. In addition to cost-savings, this low-profile entry accepts a variety of gripping […]
Design software adds 8 million connector models
Nicomatic and SnapEDA are releasing computer-aided design (CAD) models for over 8 million of Nicomatic’s connectors to help engineers bring their designs to life faster. A printed circuit board (PCB) is built with many small components, each of them with special characteristics and features. Previously, engineers had to design CAD models for each of them, […]
Why should you be using rigid-flex PCBs rather than flex PCBs in your next project?
Rigid-flex or rigid-flexible PCBs are the preferred interconnection circuits in today’s electronics. They have simplified the PCB assembly with superior mechanical stability and electrical reliability features. The driving factors for their popularity are reduced product weight, compact packaging, and quick assembly. Rigid-flex PCBs were designed primarily for critical interconnections in […]
Chip-size socket boasts -1dB insertion loss
Ironwood Electronics’ chip-size socket connects LPDDR5 to the system PCB with minimal signal loss. The supported device size is 14x14mm, 21×21 array, 0.65mm pitch BGA 441. Once the socket is soldered down to PCB, the device can be simply plugged into it. This Grypper socket has excellent electrical performance of – 1dB insertion loss greater […]
What causes signal attenuation in a PCB and how can it be controlled?
Except for the most basic designs, system clock rates are inexorably creeping upward across a wide range of applications, from 5G telephony to automotive advanced driver assistance systems (ADAS), medical, industrial, and mil/aero systems. As frequencies rise into the GHz range, the need for impedance control to minimize signal attenuation and protect signal integrity gets […]
Why should you boundary-scan all your manufactured PCBs?
By Suresh Patel, Sales Engineer, Mer-Mar Electronics The Boundary-scan, aka JTAG (Joint Test Action Group), is the IEEE 1149.1 standard used to verify and test Integrated Circuits (IC) interconnections on the PCBs. Using the boundary scan in PCB production will effectively reduce manufacturing costs, accelerate test automation, and improve PCB quality with better fault coverage. […]
Shielded panel and PCB connectors expand harsh environment capabilities
TE Connectivity is extending its time-tested 369 connector series with the new 369 shielded rectangular panel and PCB connectors for environments that demand ambient EMI noise protection. These connectors incorporate the benefits of the 369 series and create opportunities with additional applications such as ethernet, power distribution and mixed signal/power devices. “The combination of shielding […]
