Electroless Copper Plating
Non-plated copper
Copper is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is rather soft and malleable, and a freshly exposed surface has a pinkish or peachy color. It is used as a ......

Electroless copper plating patent
No Plating Copper Patent
With the continuous progress of technology, the selection of decorative materials for products has also become more and more diverse. Plating copper has always been loved by people due to its low cost and good decorative effect. Plating copper requires a plating method to......
Machinability
Cutting Processability
Cutting processability is a term used to describe the ability of a material to be cut into a specific shape. The processability of a material is largely determined by the mechanical properties, such as the strength, ductility, melting point, deformation rate, and other vari......
surface condition
Surface State
Surface state, in physics, refers to the surface electrons of a material which have been atomically modified during preparation of the surface to create a region of electric conductivity. The states on the surface are generally different from those of the bulk due to the unique elec......
complex section pass
Complex Section Holes
Complex section holes are large holes which are cut into a material in order to create complex shapes. The size of these holes may vary depending on the application but they are commonly large enough to allow a person to comfortably pass through them. These holes can be cut ......
dry friction
Friction
Friction is the force that operates when two objects rub against each other. We experience friction almost everyday in one form or another. For example, when you try to move a heavy piece of furniture across your floor, friction between the floor and the bottom of the furniture makes it d......
Precious Metal Thin Film Materials
Palladium Thin Film Material
Palladium is a rare, silvery-white metallic element of the platinum group of the periodic table. It has the chemical symbol Pd and atomic number 46. It is found mainly in South Africa, Russia and Canada. As a precious metal, palladium is used in jewelry and in electro......

A Lesson in Acceptance
Living in acceptance is much easier said than done, but it is the key to living a life free of previously damaging thoughts, beliefs and expectations. To develop an understanding of acceptance, it is important to learn the various levels to which it can be incorporated into......
lubricant additive
Lubricating Additive
Lubricating additives are compounds that are added to base lubricants—such as oils and greases—to enhance the lubricity and other performance characteristics of the lubricant. These substances are usually added to the base oil or grease in small amounts to help reduce frict......
washing
Introduction
Laundry is an important part of life, especially in the modern world. It is the process of washing clothes and other items, such as bed linens and towels, to remove dirt and stains. Different cultures have their own traditions for how this is done, with some relying on machines to do......
