LearnEMCAutomotive Printed Circuit Board Layout

Printed circuit board layout is often the single most important factor affecting the electromagnetic compatibility of automotive systems. Boards that are auto-routed or laid out according to a list of design rules do not usually meet electromagnetic compatibility requirements on the first pass; and the automotive systems relying on these boards are more likely to require expensive EMC fixes.

RecyclingWikipedia

Recycling is the process of converting waste materials into new materials and objects. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. Recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing: energy usage, air pollution (from incineration), and water .
