Targeting Through Holes in Printed Wiring Boards (PWB) – Use of Reference Pins

Targeting Through Holes in Printed Wiring Boards (PWB) – Use of Reference Pins

When using the PC-MET and PWB-MET targeted grinding fixtures from Buehler, it’s necessary to set the total grinding distance from a reference pin on which the sample is mounted to the feature of interest.  In the standard equipment, this distance is set to 0.150” as shown in the diagram. The perfect target is reached by …

Sectioning of Electronic Components

IsoMet High Speed

Introduction Sectioning of electronic components for quality control or failure analysis can be challenging as care must be taken to ensure the true structure is revealed, free from preparation-induced artifacts. Historically, sectioning processes that were highly damaging to the sample were used, which could induce artifacts that could easily be misinterpreted as manufacturing defects or …
