Mirror-Bright Silver Plating from a Cyanide-Free Bath

ilver has good electric conductivity and solderability and possesses S excellent electric characteristics as a contact and is thus widely used for plating electronic industrial parts. A cyanide plating bath is most often used, but the cyanide compounds have strong toxicity and a large amount of the cost is rxpkd for securing safe working conditions and waste treatment. Because of this, many cya...

Formation of Au Microbump Arrays for Flip-Chip Bonding Using Electroless Au Deposition from a Non-Cyanide Plating Bath

The formation of Au microbump arrays for flip-chip bonding was investigated using an electroless Au plating bath. Generally, electroless Au deposition gives a low deposition rate, preventing the fabrication of Au bumps with heights of more than 5 μm. To overcome this problem, we developed a new electroless Au deposition process that employs a non-cyanide bath. This process delivers a high depos...

Electroless Nickel Plating: Bath Control

In this paper, bath control is proposed for the electroless nickel plating through holes board process. The main parameters of the product (board) – thickness of the plating film and phosphorous content – are stabilized at constant levels using optimal tracking control. The set point for control is calculated from the model in dependence on the current state of the process. The pH-index and nic...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
