PCB Systems Vibration and Acceleration Simulation Solution Expands

Mentor Graphics Corporation announces its new Xpedition vibration and acceleration simulation product for printed circuit board (PCB) systems reliability and failure prediction. As the industry's market share leader in PCB design software, the Mentor Graphics® Xpedition product augments mechanical analysis and physical testing by introducing virtual accelerated lifecycle testing much earlier in the design process. This is the industry's first PCB-design-specific vibration and acceleration simulation solution targeting products where harsh environments can compromise product performance and reliability, including the military, aerospace, automotive and industrial markets.

Traditional, physical HALT (highly accelerated lifecycle testing) is conducted just before volume manufacturing, and requires expert technicians, which can result in costly schedule delays. Bridging mechanical and electronic design disciplines, the Xpedition product provides vibration simulation significantly faster than any existing method. This results in increased test coverage and shortened design cycles to ensure product reliability and faster time to market.

The Xpedition component modeling library is the most extensive in the industry, comprised of over 4,000 unique 3D solid models, which are used to create highly defined parts for simulation. The 3D library allows users to easily match geometries to their 2D cell database. Designers can assemble the parts models on board and automatically mesh them for performance analysis, including stiffeners and mechanical parts. The system modeling tool is ultra-fast since it can model over 1,000 components per minute.

The Xpedition product can also perform acceleration stress simulation for specialized applications. This feature provides safety factor simulation for constant acceleration conditions, pin-level Von-Mises stress, detailed stress and deformation plots, and three- axes user-defined force vector (X, Y, Z) simulation. These features are developed for safety-critical applications such as those targeting the mil-aero markets.

Xpedition Vibration and Acceleration Solution – Key Features
•Simulate during the design process to determine PCB reliability and reduce field failure rates.
•Detect components on the threshold of failure that would be missed during physical testing.
•Analyze pin-level Von-Mises stress and deformation to determine failure probability and safety factors.
•Automated simulation setup, significantly faster than existing methods.
