What is SEM EDS as Internal Material Analysis?

  • Posted by Francisco Javier Aparicio Rebollo
  • On May 2, 2019
  • 0
This analytic technique may provide both qualitative and quantitative information of the composition of a surface, i.e. identification of the elements and the element weights, respectively. The technique relies on the detection and spectroscopy of secondary radiation (X-Ray) emitted when a high-intensity incident beam of electrons impinges upon the materials placed in its path. The SEM – EDS Internal Material Analysis (also known as EDX or EDAX) can be performed in accordance with MIL-STD-883, MIL-STD-750, MIL-STD-1580 and ESCC 25500 requirements.

Identifying Leakage Pathway with a Penetrant Dye Gross Leak Test

  • Posted by David Ramirez - Cruzado
  • On March 13, 2019
  • 0
Penetrant dye gross leak test is used to identify leakage pathways within hermetic and non-hermetic devices, such as glass body devices or plastic encapsulated parts. The test provides a definitive view of the leak paths including cracks, voids, delaminations and other fractures.

DC power – Use of Substrate Attach Strength – Die Shear Strength Method

  • Posted by José Cándido Vázquez Cárdeno
  • On February 13, 2019
  • 0
The purpose of the test is to determine the strength of the element attachment system when subjected to force in the Y1 axis, and thus to determine the integrity of materials and processes used to attach semiconductor die or surface mounted elements to package headers or other substrates. The implementation of this test includes material evaluation and process control.

Test Methods in Electronic parts. The Vibration Tests

  • Posted by María Teresa Rodríguez
  • On February 13, 2019
  • 2
The purpose of vibration tests is to evaluate the effect caused on component parts by vibration in a specified frequency range. The samples are subjected to testing under different conditions, as described below, in accordance with the respective applicable standards. The test conditions differ in terms of duration, frequency range, vibration waveform, amplitude, etc.
