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

Mari Carmen López
March 13, 2019
0
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).

The paper describes the activities and results of an ESA-funded project concerned with the assessment of optical amplifier technologies and products for applications in fiber optic subsystems of future satellite payloads. Onboard applications are briefly introduced, together with associated system-level requirements. Optical amplifier technologies, research achievements and products are reviewed.
Vibration

Control Strategy, an accelerometer perspective

María Teresa Rodríguez
May 21, 2020
0
An accelerometer is a sensor that measures acceleration. These sensors can be used in shock and vibration measurements. The location of the control accelerometer is a key decision when vibration tests take place, as it can roughly affect the results in this kind of tests with small components. Commonly, the control accelerometer is placed in one of two areas: on the platform of the shaker or on the fixture.

Mounting Guidelines: PCB Board Design and Handling

Tomáš Zedníček
February 27, 2020
1
Board Design and Component Pre-Assembly Preparation The leads of leaded components shall be bent and often cut to the right length before they are mounted/soldered to the substrate. Lead cutting, bending and mounting are operations that may be hazardous if they are not performed properly.
Example of simulation results

How can failures in vibration tests be avoided?

María Teresa Rodríguez
May 16, 2019
0
As it has been mentioned in “Vibration Test on Hi-Rel for EEE Parts”, vibration tests are important to check the reliability of the components/assemblies. These tests can be a headache and suppose a great cost if the design of the device and the fixing tool are not properly done. Simulation tools are the key to anticipate to the problems reducing costs and lead times.
