July, 2016 Tech-Etch: Supershield
Gaskets Protect from the EMI Environment
MODEL 903 QUAD SITE TRI-TEMP THERMAL TEST HANDLER
Plymouth, MA — Tech-Etch, a provider of shielding technology, has introduced its Supershield 1000 se- ries of silicone or fluorosilicone elas- tomer gaskets for environmental seals and EMI shielding. The gaskets are filled with conductive metal to provide the shielding. The Supershield family uses
eight basic conducting media: Super- shield 100 with carbon, 200 with nickel graphite, 300 with silver (low density), 400 with silver nickel, 500 with silver aluminum, 600 with sil- ver-plated glass, 700 with pure sil- ver, and 800 with silver-plated cop- per. Durometers are available from 40 to 80. Supershield can be supplied in a
• Ideal for any engineering environment
• Easily accepts production handler contactors and DUT boards
• -55 °C to +155 °C hot, cold, and ambient test
• Simple, low cost changeover kits (All components fit in a 9”x12” box)
• Camera-aided alignment ensures precise changeover

Segger Intros Fail-Safe Operating System
Winchendon, MA — Segger, a suppli- er of embedded systems development tools, is enabling engineers to add higher degrees of security to their de- signs with its latest product offering —embOS-MPU. The software is a variant of the company’s high- performance, zero interrupt la- tency, real-time operating system (RTOS) that is optimized for min- imal memory utilization. It uses the memory protection unit (MPU) or memory management unit (MMU) capabilities of the microcontroller to protect a sys- tem from the potential harm posed by errant threads. With embOS-MPU, the failure of a par- ticular task will no longer impact the entire system. The operating system facili-
ware to generate and verify digital signatures, and the TLS-solution emSSL, the company is now offering software for the growing field of data and product security.
tates the creation of an unlimit- ed number of privileged and un- privileged tasks. Unprivileged tasks receive a set of restricted rights, such as memory write access and message box access. When an unprivileged task attempts to violate predefined limits, or causes a system error (such as stack overflow), the task is imme- diately terminated. In addition, the software enables a developer to in- stall a callback function which is ac- tivated if an unprivileged task is ter- minated. This application-defined routine can take whatever action is necessary when this exceptional con- dition is triggered. For instance, it could log the problem and recover from the unexpected situation to re- store full function. It could gracefully degrade system performance, or it could shut the entire system down in a fail-safe manner. Segger software products in-
embOS-MPU operating system allows the creation of different privilege levels.
