Vacuum Coaters precious metal coating alternative processes

Vacuum Coaters precious metal coating alternative processes

Vacuum Coaters precious metal coating alternative processes, reduce the consumption of alternative precious metals precious metal plating process. There are more mature alternative to the ternary alloy plating silver plated.
(1) on behalf of the ternary alloy silver plating
Copper Tin Zinc Alloy Plating due to bright silver and anti-tarnish performance is better than silver, and thus outside the assembly of connectors for commonly used instead of silverware in the electronic connector industry, then the main whichever appearance since bright colors and easy to change color, the inner conductor is still using silver conductive properties to ensure not a big impact.
Ternary alloy process is as follows: a self-test a chemical degreasing a washing hung a washing an ultrasonic degreasing a hot water wash a one-etching a degreasing washing a wash of an electrochemical activation of a washing a washing - washing one a pre-wash a copper one washing a washing acid copper plating an activation one a wash a wash a ternary alloy plating a pure water a washing and drying a hot water one a self-test an inspection.

Domestic and vacuum equipment

Domestic and vacuum equipment

Some say the most durable German vacuum equipment, vacuum equipment, the most beautiful of Japan, South Korea, the most tangled vacuum equipment, vacuum equipment China's most ugly. In fact, many people do not find the same configuration for domestic and imported products at the same price or contrast ratio, the heart inside the moon always kind of feel more round. After China became the world's factory, foreign processing equipment have been in China, of course, is that they use the technology.
In fact, whether imported or domestically produced equipment at the same price will not differ too much, do not own a lot of domestic R & D capabilities, without its own core technology manufacturers, buy a different quality of different brands of vacuum equipment parts are assembled into a finished (vacuum equipment contains components), the higher the price the better part quality, cheap quality parts using vacuum equipment is relatively poor, since the parts can do the same, technology, domestic equipment how there might be a difference than abroad? Some have their own R & D capabilities of equipment manufacturers, their equipment will be developed where there are some advantages. Of course, it is undeniable that the country's own technology to be worse than in some countries, if a vacuum device all with the domestic manufacturers developed their own brand products, in terms of quality and performance, but perhaps more than Germany, Japan's machine, but it has price advantage.
Now domestic vacuum coating machine is mainly imported from Germany, Japan, Korea equipment.
Germany is relatively expensive vacuum equipment, vacuum equipment with light control Japan's slightly more expensive, with only external crystal controlled in two hundred or so, with light control, crystal controlled, the ion source of about five million. Price Korea vacuum devices with light control, crystal controlled, the ion source of nearly two-thirds of Japan around.
In fact, many foreign brands of equipment are domestic procurement of hardware, domestic brands are foreign buyers a lot of hardware equipment, vacuum equipment, the best choice is based on the production of products to select the machine, such as the election computers in general, do not buy brand machine, assembly cost maybe higher.

PVD coating technology major application industries

PVD coating technology major application industries

Applications PVD coating technology is mainly divided into two categories: decorative plating and plating tool.
Decorative plating main purpose is to improve the performance and appearance of the decorative color of the workpiece while the workpiece is more wear resistant prolong its service life; this area is mainly applied in various areas of the hardware industry, such as door and window hardware, locks, bathroom hardware and other industries.
Tools plated main purpose is to improve the surface hardness and wear resistance of the workpiece, reducing the friction coefficient of the surface, and improve the life of the workpiece; this area is mainly used in a variety of knives, scissors, cutting tools (such as turning, planing, milling , drills, etc.) and other products.

Film, thin film coating on the vacuum introduction

                            Film, thin film coating on the vacuum introduction

Film: the film can be considered a two-dimensional material. In the strict academic sense, that only aggregate thickness is less than the thickness of the material characteristics of a real film, otherwise it is generally thin material. Characterized thickness: is the nature of the use of certain basic materials phenomenon will occur abnormal changes in the case of thin material thickness aggregation determined, i.e., when selected for a physical or mechanical properties different from the reference beginning to show it typically has a thickness characteristics when, is characterized in substance to the film thickness.

The main properties of the film：

Thickness: The more uniform the better, should generally be controlled within a range, such as 5, which is about the size of the workpiece coating system

Film surface morphology: transmission electron microscope by scanning electron microscopy (SEM) (TEM) analysis showed the like particle state, the availability of dense film surface, defect status, the annealing treatment on the membrane surface and other information.

Membrane organization features: X-ray diffraction analysis of the composition of the film, and other information available to the purity of the film. Film stress: the smaller the better films of internal stress, the internal pressure of the annealing process can maximize the release of the film.

Characteristics of the film and the substrate contact: mainly refers to the adhesion between the film and the substrate, of course, the stronger the better adhesion, the film appears to avoid missing the open and so on.

Dense membrane: mainly refers to film hardness and abrasion resistance, to avoid the open circuit external scratches caused.

Chemistry membrane, thermal stability: the requirements for the metal film layer of the metal film layer prepared resistivity as low as possible, close to the bulk resistivity.

Film analysis commonly used methods:

Scanning electron microscopy SEM analyzes 10nm resolution is generally more than surface information, sample preparation simple.

Transmission electron microscopy TEM analyzes structural information, resolution of less than 1 atom, sample preparation difficult.

XRD analysis of the structure is the information, but can not analyze micro-structure information for the film, XRD given direction, SEM choose a good area, TEM-depth analysis, which is a combination of boxing.
