Electrical, Electronics and PCB Design Safety & Compliance by Udemy
Learn the most important aspects and methods for designing safe electrical and electronics products and applications.
Course Highlights
- Understand electrical product safety concepts, classifications and terminology
- Understand the most important electrical safety requirements for an electrical/electronics product design project
- Understand the concepts of clearance, creepage and solid insulation and be able to design the related safety measures
- Understand the importance of critical components and be able to verify if such components are properly certified/approved. Examples with transformers and capacitors
- Understand IP protection against ingress of water and solid parts and properly choose the best solution for a particular design
- Be able to draw insulation diagrams, a very important tool for product development, in order to represent the insulation strategy and the product compliance
- Be able to find and use technical international standards with respect to electrical products safety
- Understand where the safety aspect learned in the course belong in the product design/development lifecycle
- Examples with households appliances design
- Properly set clerance and creepage values in PCB design CADs, like Eagle Layout PCB Design software (contents applicable also to other CADs software)
