:: DfR Solutions - Why Do Temperature-Based FEA? & Optimization of Capacitive Touch Sensors Through Simulation

Why Do Temperature-Based FEA?
Thursday, April 19
Presented by Dr. Natalie Hernandez

Unless you’re in a perfectly controlled, relatively benign environment, there will be thermomechanical stresses impacting your product. This can occur while driving your car or sending a submarine to explore the Mariana Trench or launching a spacecraft to circle the sun. The combination of thermal and vibration loading conditions significantly impacts the lifetime of the components in your printed circuit card assembly (PCBA). Understanding the responses of your PCBAs under these environmental stressors is key to answering that ultimate question, “When will my board fail?”

With the release of Sherlock v.5.4, the industry can assess the effects of temperature-dependent vibrational and shock events on the fatigue life of PCBAs. Most importantly, the analyses now incorporate temperature-dependent material mechanical properties existing throughout the assembly. One can quickly and easily model their designs and run a temperature-based simulation to discern more accurate fatigue predictions based on real-life, extreme environments.

Optimization of Capacitive Touch Sensors Through Simulation
Thursday, April 26
Presented by Fieldscale (Guest Presenter)

Capacitive touch sensors are replacing all types of mechanical switches in a very wide range of applications due to their low cost and high reliability: white goods, automotive interior, aviation, consumer electronics are only some of them.
Interfaces of capacitive touch systems typically consist of the sensor and the controller that combines a capacitance-to-digital converter (CDC) together with a microprocessor. The controller drives the sensor through conductive lines, usually called “traces”, on a standard PCB or flex circuit.
The specifications of the different applications set limitations on the sensor’s sensitivity. Traces routing, proximity to conductive parts, shielding elements etc. influence the final design. More often than not, you are left with a design that in theory follows generic guidelines but does not function when installed in the end product.

Join Fieldscale for this live webinar to learn:

  • Touch buttons and sliders simulation tips
  • Trace routing optimization techniques
  • Material selection do’s and don'ts

This webinar is ideal for touch sensor designers from automotive, avionics, white goods or industrial applications that have no expertise in simulation software and want fast answers on how to move on with their project.
