Semi-Additive Process (SAP) Utilizing Very Uniform Ultrathin Copper by A Novel Catalyst

The demand for miniaturization and higher density electronic products has continued steadily for years and this trend is expected to continue,  according to various semiconductor techno .. read more

Insertion Loss Investigation Using a Non-Oxide Alkaline Surface Treatment for Inner-Layer Copper

The industry is moving toward using exotic dielectric materials with a very low loss tangent to improve insertion loss performance. This leads to the result that the signal loss attenuation .. read more

Signal Transmission Loss due to Copper Surface Roughness in

Higher-speed signal transmission is increasingly required on a printed circuit board to handle massive data in electronic systems. So,signal transmission loss of copper wiring on a printed circ .. read more

Insertion Loss Reduction through Non-Roughening Inner-Layer Surface Treatments

As channel speeds approach 25 Gbps,near the expected maximum bandwidth for traditional copper-based PCBs,every available tool to minimize total insertion loss in the board material system will .. read more

Determination of Copper Foil Surface Roughness from Micro-section Photographs

Specification and control of surface roughness of copper conductors within printed circuit boards (PCBs) are increasingly desirable in multi-GHz designs as a part of signal-integrity failure an .. read more

Electrodeposited Nanocrystalline Copper for Printed Wiring Board Applications

Nanocrystalline and ultra-fine grain copper can potentially offer increased reliability and functionality of printed wiring boards due to expected enhancements in strength and achievable wiring .. read more

Non-Classical Conductor Losses due to Copper Foil Roughness and Treatment

In high speed digital interconnects; signal attenuation is a result of both dielectric losses and conductor losses. Previous works have showed in detail,the characterization and modeling effort .. read more

High Frequency Conductor Loss Impact of Oxide and Oxide Alternative Processes

In most of today's high speed digital interconnects,the signal loss associated with the printed circuit board (PCB) is the dominate factor. Material selection,trace geometry,and choice of coppe .. read more
