Failure Mechanisms in Embedded Planar Capacitors during High Temperature Operating Life (HTOL) Testing
High temperature operating life (HTOL) testing was performed on embedded planar capacitors (with epoxy- BaTiO3 composite dielectric) by subjecting these devices to highly accelerated temperatur

A Test Methodology for Copper Dissolution in Lead-Free Alloys
Lead-free selective soldering can result in extended times at high temperatures,which in turn can result in excessive dissolution of exposed copper,such as plated through holes. This phenomenon

Fluid Flow Mechanics -Key to Low Standoff Cleaning
Over 3 years ago,Zestron initially addressed cleaning underneath 4 MIL standoff components. With the emergence of lead-free and even smaller components new challenges have now arisen to include
