Radiation degrades EEE components and generates device perturbations that could lead to its malfunction or destruction. These effects are highly dependent on the radiation type: gamma radiation, heavy ions, protons, etc., but also on the device technology, the manufacturing lot...
The use of radiation tools is justified as a complement of radiation test to verify and optimize the radiation hardness assurance process in the new space market and reduce some cost without a significant loss of the confidence level.
Alter Technology (formerly Optocap), is a leader in the design, manufacture and test of High Reliability Micro and Optoelectronics modules for Harsh Environments. We have experience in a number of high reliability and harsh environment markets such as Aerospace & Defence, Space...
New space missions include more extreme requirements of storage and operational temperatures and vacuum conditions exceeding standard -55ºC / +125ºC conditions Miniaturization implies increase higher power dissipation and hence max junction and PCB temperatures.
Space radiation environment is an important failure causing factor in space vehicles. Traditional reliability prediction method did not include the space radiation environment reliability. It’s the time to set up a method of space radiation environment reliability prediction.
1. Admissible methods for SEE testing were determined on accounts of their realization at Roscosmos Test Facilities. 2. The SEE Testing Aids (based on ions, proton and laser sources) were created and are currently in operation. 3. The Roscosmos Testing Aids provide tests for all...
Radiation assurance test is very interesting, but also very complicated. It always needs joint efforts to find better solutions, and BMTI is looking forward to collaborating with related partners to do this.
Third party dice radiation test for a manufacturer has never been an easy thing thanks to the exigent requirement from the users and difficulties from the die side. Things are becoming worse since the semiconductor came into a sub-micron and deep sub-micron era. New challenges...
Given a general introduction on testing optical materials for use in radiation environments. A special emphasis is given to thin optical coatings, optical fibers, and fiber Bragg gratings. Here the test procedures are much more challenging than for bulk materials. The challenges...
ALTER TECHNOLOGY will execute different tasks, such as the detailed definition of the space radiation engineering activities to be implemented for JUICE and aimed at reducing (to the maximum extent feasible) total ionizing dose levels for platform equipment and instruments; the...
Alter technology activities: Design and development of a custom camera Characterization of pixel performance On-line monitoring of electrical parameters and acquisition of images in different working conditions (radiation, temperature, vacuum) Radiation of image sensors Total...
In space applications, optocouplers may need to work at very low temperatures. Under this low temperature operating conditions, the device degradation subjected to radiation exposure may show different behaviour compared to a standard radiation test under room temperature. The...
