Evaluating Electrically Insulating Epoxies

Dielectric constant, dissipation factor, dielectric strength, surface and volume resistivity are all fundamental electrical properties of epoxies. How they are measured, what values are desirable and how they react to changes in temperature, fillers and other variables are considered in this paper. The specific composition of resin and curing agents will also affect the electrical properties of a cured epoxy system. Three major types of curing agents are explained in this paper along with their benefits and trade-offs with respect to electrical properties.

Made in Space: 3D Printing in Zero-G

NASA’s In-Space Manufacturing (ISM) project is responsible for developing the manufacturing capabilities that will provide on-demand, sustainable operations during NASA long-duration missions to destinations such as Mars. The very first step in the initial part of ISM was getting the first 3D printer into space. A 3D printer had never flown in space until the 3D Printing in Zero-G experiment was launched on SpaceX-4 on September 21, 2014. This demonstration was the first attempt to test the effects of microgravity on additive manufacturing in space. The printer was designed and built by Made in Space under a NASA Small Business Innovation Research (SBIR) contract. Learn how NASA and Made In Space worked together to design, develop, and deploy the printer, and how they are taking the next steps to create an Additive Manufacturing Facility in space.

Successful Test Management For Systems Engineers

Designing a reliable test strategy requires broad, strategic thinking. The goal of verification is to ensure you release a best-quality system that meets customer expectations as documented in your early design concept and requirements gathering phases. To maximize the value of your test process, test your product objectives early.

Delivering Roadworthy Designs: Automotive Electronics Circuit Protection Overview, Applications & Standards

Today’s automotive designs include nearly 100 microprocessors; that number is expected to double in five years. From in-dash displays to connected technologies and safety systems, all onboard electronics require circuit protection to maintain reliability. The major sources of electrical hazards in automotive systems are electrostatic discharge (ESD), switching loads in power electronics circuits, and lightning. Overcoming transient surges that can harm the vehicle’s electronics, whether under the hood or in the cabin, is one of the biggest obstacles of system design.
