Electroplating technology is a functional finishing technology. Its alloy coating has excellent wear resistance, corrosion resistance, coating thickness uniformity and high density. It has a wide range of applications in electronic products. With the rapid development of the electronics industry, the high demand for electroplating technology increases. Many new technologies, new products, new techniques are constantly emerging.


NCVM also known as discontinuous titanium dioxide coating technology or non-conductive plating technology. It is from one edge of the ordinary vacuum plating of high-tech. Vacuum plating,Non conductive coating technology NCVM Articles referred to as the VM, it is abbreviation of vacuummetalization. It refers to the metallic materials under vacuum conditions, the use of specific chemical and physical means of organic conversion, so that the metal converted to particles deposited or adsorbed on the surface of the plastic material to form a membrane, which is our so-called coating. The conductive vacuum plating is also known as NCVM. The process is higher than ordinary vacuum plating, the processing process is much more complex than the ordinary process.

NCVM is plated out of metal and insulating compounds, film, using each other discontinuous features, get to the final appearance of the metallic finish and does not affect the effect of the wireless communication transmission. First to achieve the non-conductive, to meet the normal use of wireless communications products; Second, we must ensure that the metallic finish this important appearance requirements; combined with UV coating and the coating layer, the ultimate guarantee of the physical properties and weather resistance of the product to meet customer needs . NCVM can be applied to a variety of plastic materials, such as PC, PC + ABS,, the ABS, PMMA, NYLON, such as engineering plastics, it is more in line with environmental protection requirements of the production process, alternative technologies for electroplating products of the chrome-free (Non-Chrome), applicable to all the required surface treatment of plastic products, especially suitable for signal transmission and reception of 3C products, especially in the vicinity of the antenna cover, such as Mobile-Phone, PDAs, smart phone, GPS satellite navigation, bluetooth headset.

The main features of NCVM is a combination of the characteristics of the traditional vacuum coating technology, the new coating technology, new materials, to make the different colors of the ordinary neodymium fluoride vacuum plating metal play the beautification function of the workpiece surface. NCVM technology system finished by high-voltage table tens of thousands of volts of high voltage test is not turned on or not breakdown. It is precisely because of its non-conductive when the recipient or the emission signal of the mobile phone or Bluetooth headset, the electromagnetic fields generated by the conductive coating of the stocking, which does not affect the phone's RF (radio frequency) performance and ESD (electrostatic discharge) performance that makes wireless products to achieve better received signal, no noise, nor will it have any impact on the human body. From the point of view of electrical properties, it can be tested by conducting tests and electronic interference. From the vacuum coating, it can also ensure normal physical and weathering tests, such as adhesion, abrasion resistance, alcohol resistance to artificial sweat and hot and humid storage. Communications products chassis NCVM process, the antenna module without re-design the circuit ground to the board, thus saving on the antenna module detection, and cost savings; the appearance of the metallic finish of the products is relatively strong, thereby increasing the technological content of products, increase the added value of the product.

In addition, NCVM can make the plastic with metallic and semi-translucent control. It reflects the metal texture and light penetrating. In the NCVM process, it often uses the translucent or semi translucent characteristics to make the product changeable. Then the appearance becomes more beautiful. Source:
