High Reliability Flexible Circuits for the Medical Marketplace

Tech-Etch manufacturers high reliability flex circuits used in the diagnostic imaging, patient monitoring, cardiac management and life science industries. Flexible circuits provide the thinnest and lightest interconnect method available. Their extreme thinness makes them very well suited for dynamic applications where the flex will be in constant or periodic motion. They contribute to reducing overall system complexity by facilitating assembly and eliminating wiring errors. Flexible circuits will conform to the available geometry for connections of electronics located on different planes within the finished electronic device. This capability is sometimes referred to as 3D packaging.

Multiphysics Modeling of MEMS Devices

There are many excellent reasons to simulate microelectromechanical system (MEMS) devices. For example, if you're going to create a new product or process, such as a capacitive pressure sensor, you'll first want to get the concepts right. The most important decisions are often made early in the product development cycle when multiphysics simulation can give you the valuable insight you need. The benefits of multiphysics simulation can also extend easily to the design and optimization of a product by reducing the time and money spent on prototypes. And, if you integrate multiphysics simulation with manufacturing and quality assurance, you'll end up with a product that's much better understood and better characterized.

Overcome Challenges of Your Highly Constrained PCB Designs

Layout constraints are an essential part of a PCB design. As the technology in modern electronic devices has become more complex (e.g. increasing speed, decreasing rise time and supply voltage values), signal integrity issues have become a primary concern. For many designs, this means a large percentage of nets require PCB layout constraints to meet signal integrity requirements. This brings two major challenges: creating a proper set of layout constraints for your design and applying those constraints during the PCB layout design process. This paper shows how to address the challenges of highly constrained designs.

Removing the Gap Between ECAD and MCAD Design

For ECAD and MCAD to collaborate in “real-time” a direct method of communication that facilitates a shared flow of data back and forth between design teams is required. This flow must support “what-if” scenarios of design baselines and change proposals along with the ability to counter-propose changes. Once design agreements are made, the flow must also dynamically update the design databases. This unique ECAD-MCAD (EDMD) collaborative environment has not been available until now. This desktop PCB design provides a real-time integrated ECAD-MCAD collaboration environment that enables Electrical and Mechanical design teams to work together throughout the entire design process.
