Effects of space environment on electronic components

OBJECTIVE :

This training will allow listeners to know the effects of space radiation environment on electronic components in order to better take into account the constraints in the design or development of a project related to space.

COURSE DURATION AND TIMETABLE :

The training last 2.5 days (15 hours) and is composed of :

  • 4 talks with a duration of 3 hours
  • 1 practical work of simulation with a duration of 3 hours

GENERAL APPROACH :

The space environment is well known to be an aggressive environment in terms of radiations. From the perspective of cost reduction it is very important to better specify constraints while controlling margins.

This course allows to understand the various radiative constraints affecting the embedded electronic components and to consider appropriate optimization solutions.

PREREQUISITE :

Level:

A university technical basic training or engineering school is desirable to take full advantage of this training.
