PCB Failure Analysis: Pad Cratering

by MC Lopez

Pad Cratering One of the major failure modes encountered in PCB assembly is Pad cratering. This term is coined to describe a fracture at the pad/resin interface (adhesive failure) or within the resin beneath pads (cohesive failure) that extend along the whole pad length (see the...

XRF: X-Ray Fluorescence Spectroscopy | Hi Rel Parts

by Francisco Javier Aparicio Rebollo

XRF is a non-destructive and quick analytical tool to determine the chemical elements present in the specimen. In particular, it combines low detection limit (particularly in the case of heavy elements) with quick and easy sample preparation. Continue reading

Thermoreflectance Thermal Imaging | Hi Rel Electronics Parts

by Media ATN

Submicrometric-nanometric objects nowadays present in the design of integrated circuits induce singular heat transport phenomena leading to the formation of hot-spots or strong temperature gradients at specific local points, which compromises the suitable operation and... Continue reading

Resistance to Solvent or Marking Permanence Test | EEE Parts

by Jesús Enrique Barbero Muñoz

The purpose of this test is to verify that the markings on component parts will not become illegible when subjected to solvents (e.g. during the board cleaning process after parts assembly) or during normal handling, and that the solvents employed for the test will not cause... Continue reading

PIND test – Particle Impact Noise Detection | EEE Parts

by Adrián Cembrano Pérez

PIND ( Particle Impact Noise Detection Test )  testing is performed in order to detect the presence of loose particles inside a device cavity. Loose particle contamination is often caused by dirt, fibers, solder residues and other elements trapped inside the cavity during the... Continue reading

Focused Ion Beam (FIB) Micro-Sectioning | HI Rel Parts

by Francisco Javier Aparicio Rebollo

Focused ion beam, also known as ion milling, is a technique used particularly in the semiconductor industry and materials science for site-specific analysis, deposition and ablation of materials. Since it is destructive to the part, FIB technology is used for micro-sectioning in... Continue reading
