With their extra jolt of heat, lead-free solder processes can be tough on the engineering plastics used to make connector housings. DSM Engineering Plastics, whose Stanyl nylon 46 resins go into many types of connectors, recently undertook an extensive design of experiments to identify the processing profiles that minimize temperature effects such as "blistering."

These free camps are designed for children ages 10 to 18. Attendees are introduced to 3D CAD software and shown how 3D printers can make their work a reality. Many classes were nearly 50 percent girls and 50 percent boys.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
