The drilling of State-of-the-Art printed circuit boards (PCBs) often leads to shortened tool lifetime and low drilling accuracy due to improved strength of the PCB composites with nanofillers and higher thickness-to-hole diameter ratio. Diamond coati...
The preparation of high-performance hard coatings on the surface of cemented carbide PCB (printed circuit board) microdrills can effectively decrease the rapid tool wear that occurs during cutting. In this study, arc ion plating technology was employ...
Precise microvia formation is a critical requirement in printed circuit board manufacturing. This study develops predictive mathematical models for the penetration depth of a Coherent AVIA LX Q-switched diode-pumped nanosecond laser in the copper foi...
