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 […]
ECO software speeds chip design tasks
To boost productivity and enhance the power, performance, and area (PPA) of advanced electronic designs, Synopsys, Inc. announced the breakthrough golden signoff ECO solution that addresses lengthy engineering design closure times. The Synopsys PrimeClosure solution combines Synopsys’ leading engineering change order (ECO) signoff solutions, Synopsys PrimeECO and Synopsys Tweaker ECO, with breakthrough innovations, delivering the fastest ECO […]
Website, app, let engineers download and import part models
SnapEDA gives engineers free access to 3D models and footprints for PCB design. Designing a PCB is hard work. You have mechanical, electrical, and thermal considerations, any of which can make or break a design. You must design your board to accommodate the footprint and packaging of every part. Obtaining the data means you must […]
Audio component CAD models compatible with PCB design tools
An online experience allows engineers to visualize and download CAD models for PUI Audio products. To save engineers weeks of design work, SnapEDA created the first search engine focused on providing trustworthy electronics CAD (E-CAD) data. Traditionally, engineers have spent hours creating the CAD models needed for circuit board design. The process of creating and […]
“Zero-height” metric threaded inserts for PCBs
Ultra-Low-Profile, Surface Mountable Threaded Inserts now include Metric and Imperial thread options. These inserts are specifically designed and packaged for use on PCBs in the same manner as other SMT components as a simplified method of adding threads to PC Boards. Manufactured from steel with a tin plate, these inserts offer an easy method of […]
IR-transparent solderable resin supports shift from pluggable to co-packaged optics
SABIC has launched EXTEM™ RH1016UCL resin, a new ultra-high-heat, near-infrared (IR)-transparent grade well-suited for injection-molded lenses used in co-packaged optical transceivers and other optical connectors. EXTEM RH1016UCL resin is one of the first IR-transparent thermoplastics that can robustly withstand the 260°C peak temperature of printed circuit board (PCB) reflow soldering while maintaining dimensional stability of […]
