Thermal Characteristics of PCB Laminates used in High Frequency Applications

As technology advances,understanding thermal management issues of high frequency PCB’s increases. There are many different aspects to consider for PCB thermal management. This paper will invest .. read more

Production of Flexible Circuits in Reel to Reel Horizontal Production Systems

Reel to reel production of flexible circuits where the substrate consists of a continuous roll is a technique commonly used in mass production. This method is an obvious solution for efficient .. read more

Comparative Analysis of Solder Joint Degradation Using RF Impedance and Event Detectors

Under cycling loading conditions,solder joints are susceptible to fatigue cracking,which often initiates at the surface where the strain range is maximized. Event detectors have been widely use .. read more

The Effect of Copper Plating Processes and Chemistries on Copper Dissolution

Implementation of lead-free assembly processes results in higher copper dissolution rate than traditional SnPb alloys. The rate at which copper is dissolved could be dependent on many factors,s .. read more

Next Generation Pattern Electroplating Process for Microvia Filling and Through Hole Plating

The use of electrodeposited copper for filling blind microvias has grown rapidly to become an essential and widely adopted process used by various Printed Circuit Board (PCB) and package substr .. read more

Uniformity of Nickel Plating Thickness in High Aspect Ratio Plated Through Holes

Nickel plating is often used on PWBs to increase wear resistance and to prevent diffusion between copper and other plated metals. The nickel plating is often present in through holes as well as .. read more

Recovery of Copper Metal in the Continuous Regeneration of Cupric Chloride Etchant

An electrochemical device has been developed that deposits non adherent copper metal powder at the cathode,and generates chlorine gas at the anode. The chlorine is contained within the system,a .. read more
