Remcom Announces XFdtd Electromagnetic Simulation Software UpdateAugust 26, 2020 | PR Newswire

Remcom announces an update to XFdtd® 3D EM Simulation Software, with new features to address 5G millimeter wave antenna design challenges including support for high-performance tuners and singularity correction. In addition, PCB import enhancements save time in the design workflow.
As mobile devices continue to grow in complexity, engineers are challenged to include more antennas in less available space within the device while maximizing efficiency. Multi-port RF devices such as tuners and switches can be utilized to optimize band coverage. To accommodate these innovations, XFdtd's Circuit Element Optimizer (CEO) now includes multi-port device functionality, enabling engineers to incorporate and test these components in their matching network simulations.
Singularity correction is a sophisticated meshing method that accurately captures highly varying electromagnetic fields around the conductive edges of geometries such as antennas or transmission lines. XFdtd adjusts the electric and magnetic field values adjacent to metallic edges during time stepping. For higher frequency and millimeter wave use cases, where numerous antennas and components create high spatial variation of fields, singularity correction can significantly improve accuracy and strengthen confidence in the expected behavior of a device.
The new XFdtd release also includes enhancements to printed circuit board (PCB) import, allowing documentation layers of a PCB to be imported alongside the geometry. These layers typically include useful manufacturer information such as the build date of the device, ID number, and more. Lastly, lumped circuit components specified in ODB++ and BRD files are also imported, eliminating the need to manually add them afterwards.
Repair of soldered components is a constant necessity in the electronics industry. Product performance enhancement, damaged components, and exchange of wrong placed components are some of the motivations behind a repair. Dispensing and placing a 400 μm pitch component manually is very time consuming and could cause collateral damage to the already populated components. A novel automatic repair method and tools with no human interaction were developed. Learn about this method…
One of my great joys as a grandfather of eight is spending time with them at the park. It doesn't take too long until I'm getting stuck on a slide that is too small for me or on the seesaw, with me on one side and them trying to lift me. At that point, they learn some harsh lessons in physics and how heavy Grandpa really is. A seesaw is a relatively simple device, but it’s a great way to explain a rather complex concept in PCB design: design tradeoffs. Each decision made throughout a design comes with inherent pros and cons.
IPC’s Kris Moyer teaches design techniques for embedding components, and he’s noticed an upswing in his students’ interest in embedded component design. We recently spoke with him about embedding component design: best practices, pros and cons, and when it makes sense for designers to start embedding.
We’re always hearing about PCB technology running into a wall. On the design side, Moore’s Law hit one such wall. On the fab side, features are now so tiny that the traditional subtractive methods have hit another type of wall. And we see OEMs who never planned to use flexible circuits wind up embracing them, because rigid boards just won’t fit into a new product’s form factor. In the February 2024 issue of Design007 Magazine, our expert contributors lay down the foundation of knowledge that designers need to be aware of to make intelligent, educated decisions about embedded design.
We’re always hearing about PCB technology running into a wall. On the design side, Moore’s Law hit one such wall. On the fab side, features are now so tiny that the traditional subtractive methods have hit another type of wall. Similarly, the popularity of embedded components is the result of technology hitting a wall, or a series of walls. In this month's issue of Design007 Magazine, our expert contributors lay down the foundation of knowledge that designers need to be aware of to make intelligent, educated decisions about embedded design.
