The space probe Rosetta was built by the European Space Agency (ESA ) with the objective of reach and study Comet 67P/Churyumov-Gerasimenko. Was launched on March 2004 from Kourou. To place it on the required orbit to rendezvous with Comet 67P/ Churyumov-Gerasimenko it received four gravity assist manoeuvres: 3 from Earth (4 March 2005, 13 November 2007 and 13 November 2009) and 1 from Mars (25 February 2007).

Studying Critical elements in PCB systems: Plated Through Via (PTV)

Mari Carmen López
March 13, 2020
Plated Through Vias (PTV) are critical elements in PCB systems and special care must be paid during their inspection in order to ensure the reliability, as they are one the main factors that determine the PCB Quality. The functionality and reliability of PTVs are dictated by: the plated through hole architecture (height/diameter), plating (thickness and quality) and other PCB general characteristics (materials and design).

Mounting Techniques Overview

Hi-Rel EEE Parts Mounting Techniques Overview

Tomáš Zedníček
April 30, 2019
IR reflow soldering IR infrared “convection” reflow is commonly used in commercial large volume SMD components mounting process. The main differences in reflow soldering processes and oven types lie in heat transfer methods – radiation, conduction, convection, and condensation. In fact, all heat transfers are used in modern reflow ovens. The heat is applied from above, below, or all directions dependent on the equipment being used. In classical infrared “radiation” reflow ovens, several ceramic heaters are transferring the heat to the assemblies, moving through the oven on a conveyor belt, by radiation.

Thickness Verification. An Introduction on HI-REL

Emilio Cano García
April 10, 2019
Coating Thickness Verification The thickness of metallic coatings is routinely determined by X-ray fluorescence spectrometry. This provides a basis for assessing the quality of coated materials and therefore influences decisions regarding disposition (acceptability) of the coated product as well as control of coating processes.

Phases of Evaluation and Qualification in Electronic Components

Manuel Padial Pérez
February 2, 2020
During the Evaluation phase, components/technologies can be expensively characterized and margins determined. If the evaluation is successful we can then proceed with Qualification, on components produced strictly as defined in the final PID (Process Identification Document) and from a given lot (actually, the first production lot). Once qualified, the component is listed in the QPL (Qualified Part List).


Qualified components, Enhanced components, Automotive parts and COTS are part of Compare all different scenarios and technical information within the platform in order to help you choosing the proper components and strategy for your Space Application.

Find in doEEEt any component included in your design is a web portal that allows you find within a database of more than 17 million components the exact solution for your need. The first database of space qualified hi rel components is now at your service.

  • Access to technical information.
  • Access to procurement information: prices, lead times…
  • Get quotations from all different manufacturers.
  • Qualification activities applicable.
  • Access to specifications, test reports, radiation information.
  • Access to available stocks.
  • DCL manager to manage your procurements.
  • Comparison of scenarios: Qualified vs. Automotive vs. COTS.
