What you'll learn:
- 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)

Course Description
Being a capable electronics designer does not make you a good one.
Being an expert in Arduino,Raspberry, firmware, embedded softwareand microcontrollers,hardware, PCB design, digital and analog design, is only a part of what designers need to know.
A beautiful and functional product can be appealing, but if basic safety rules are not taken into account even before starting the actual design activities, a poor design can endanger people and cause its designer big troubles.
This course focuses on design safety with respect to electrical/electronics application, including PCB design. It covers the most important aspects that designers need to know, and it teaches a general methodology to develop electronics and electrical applications (including PCB) in compliance with safety principles and international standards.
+++++ Have a look at the course curriculum +++++
At the end of the course:
- you will be able to find in international standards and understand the applicable electrical safety requirements foryour electronics project
- you will be able to calculate the most important parameters like clearance/creepage distance and solid insulation, to be considered during insulation, electronics and PCB design
- you will be able to set and check creepage and clearance on PCB CAD/CAM Software
- you will be able to choose the proper IP isolation against ingress of water and solid particles
- you will be able to choose critical electronics components and verify their certifications
- you will know what insulation diagrams are and how to make and use them
- you will know what international standards are, how they are made and where you can find them
- and you will understand the design process and steps toward a compliant product
so basically you will be able todesign a functional, safe and ready for the market electrical application.

We will introduce the basic concepts and techniques of electrical, electronics and PCB design for safety, teaching you the path to a project compliant with product safety legislation.
We will cover both basic electrical definitions like the product classification and more advance conceptslike creepage calculation and critical electronics components.
Throughout the course you will find practical examples on how to use these techniques on electrical and electronics household appliances design (e.g. food mixers and electric toasters), and also how to set some parameters in a CAD/CAM Software for PCB design.
We will take as a reference the most important andrecognised international safety standards, like IEC 60335 series, IEC 60529, and the like.
The last section will be dedicated to describe the whole design process, from the design specifications to final verification and validation, with a practicalexample on an electric toaster design.
------------------------------------------------------------------
The course is made essentially of video lessons, but reference to guidelines and datasheets are provided, when considered useful.
You will alsofind severaltests. We strongly recommend to take the tests before proceeding to check the concept you have learned.
If you really wantto understand the safety related part of an electrical/electronics and PCB designand complete your technical culture with this important cornerstone, this course is a must.
HAPPY LEARNING!!!
