Happy’s Tech Talk #40: Factors in PTH Reliability—Hole Voids

07/09/2025 | Happy Holden -- Column: Happy’s Tech Talk
When we consider via reliability, the major contributing factors are typically processing deviations. These can be subtle and not always visible. One particularly insightful column was by Mike Carano, “Causes of Plating Voids, Pre-electroless Copper,” where he outlined some of the possible causes of hole defects for both plated through-hole (PTH) and blind vias.

Study on Resonance Mitigation in Metallic Shielding for Integrated Circuits

07/08/2025 | Maria Cuesta-Martin, Victor Martinez, Vidal Gonzalez Aguado, Würth Elektronik
Inherent cavity resonant modes often lead to significant degradation of shielding effectiveness, responsible for unwanted electromagnetic coupling. Cavity resonant modes of the metal shielding enclosure can produce two adverse problems: the mutual coupling among different RF modules and shielding effectiveness reduction of the metal enclosure. The cabinets serve to shield certain components from electromagnetic interference (EMI). However, these cavities present some resonance peaks at 5 GHz, making it impossible to use them at higher frequencies.
