Experts in design, packaging and testing of high reliability components Engineering Expertise The experience and technical knowledge achieved by our engineers in the last years is a major lack of most space and harsh environment companies. Our engineering services support the customers to meet the stringent quality requirements of high-reliability applications. Our Ph.D. and engineers are responsible to ensure that all parts will meet the specific requirements of each project. A wide range of inspections is needed to guarantee that the parts are suitable for the entire mission life, which requires a deep knowledge of microwave technology design and measurement.

Solenoids, Contactors and Electromechanical Relays Explained

Solenoid and relay conjure visions of an ancient electromechanical world now replaced by all-electronic devices, smart motors, and more. That almost makes sense, as these two components in various forms have been with us for over 150 years. But don’t be fooled: Both are still indispensable devices … and remain viable choices for the conversion of electrical energy to mechanical motion (in the case of solenoids) or where a signal must control the on-off path of one or more other signals (in the case of relays).

Irradiation test facilities for COTS EEE components

With the growing consideration of COTS EEE components for space applications, SEE radiation testing will be a challenge. Due to the dense, complex circuits in Flip-Chip, hybrids or plastic packages with Cu bond wires, the opening of such packages is either impossible or difficult, with the risk to modify the device response. This limits the possibility to perform traditional SEE testing with standard heavy ions (<10MeV). Alternative SEE testing strategies have to be used employing high energy protons or more energetic heavy-ion beams with a proper compromise between LET and range. The presentation will provide an overview of the use and availability of the testing facilities in Europe offering high energy protons (200 MeV) and heavy-ion beams: ranging from the high energy Heavy Ions (HE) to the Very-High Energy, (VHE) and Ultra-High Energy (UHE).

Environmental testing provides a useful tool for evaluation, qualification and screening of EEE components for high-reliability applications. Various types of stresses can be applied to the products in a controlled manner thus allowing to accelerate the appearance of latent defects and consequently to assess the ability of the products to meet project requirements

Basics & Benefits of Tantalum & Ceramic Capacitors

Posted by doEEEt Media Group
On February 12, 2020

Tantalum (Ta) capacitors and multilayer ceramic capacitors (MLCCs) are two widely accepted capacitor technologies that can be employed in a wide range of electronics applications. Although both technologies perform the same basic function, they are very different in terms of their construction techniques, materials, and performance under various conditions, so it’s important to understand the potential impact of selecting one over the other.
