Advanced packaging and testing technology : ESD - DLC film coating, new business opportunities for static dissipation
In the global semiconductor supply chain, Taiwan is an indispensable link. The world-class manufacturers have increased their demand for process technology and product quality, and various suppliers are constantly developing new technologies to obtain new solutions to seize the market. The problem of electrostatic protection in the previous packaging process can be solved through Electro-Static Dissipative Diamond-Like Carbon (ESD-DLC) film coating technology. What is the electrostatic dissipative diamond-like carbon (ESD-DLC) coating technology? As the nanometer size of semiconductor components shrinks below 10 nanometers, their antistatic ability gradually declines. During the chip packaging process, they may be damaged by static electricity and affect the yield. Therefore, advanced packaging processes urgently need to solve the problem of electrostatic tolerance. ESD-DLC coating technology is a multilayer amorphous structure design, with good wear resistance. Equipped with an improved magnetic filtering arc ion system, and high chemical stability, it has excellent antistatic properties and good acid and alkali resistance, that can prolong the service life of the test carrier board as a whole by more than 3 times. It replaces the old hard anode treatment that is not resistant to alkali washing, and improves the electrostatic protection breach caused by the peeling of the film caused by collision or other cleaning factors. This surface modification technology will help bring new breakthroughs to advanced packaging processes. Technical advantages and applications of ESD-DLC coating Electro-Static Dissipative Diamond-Like Carbon (ESD-DLC) film layer  through a special film structure design can be customized to control the electrical properties of the product surface, in terms of hardness, adhesion, and wear resistance. It has excellent performance in terms of chemical resistance and chemical corrosion resistance, that has passed product application verification, which greatly improves the process yield and product service life. In addition to various packaging and testing carrier boards, the advanced surface modification technology ESD-DLC coating technology offers will not affect the original size of the product, including reflow carrier boards, tray disks, machine slides, etc. It meets strict requirements for electrostatic protection of products sensitive to electrostatics. Therefore, the scope of industrial application include semiconductors, IC packaging and testing,  transmission equipment and components, etc. It is expected to be favored and adopted in the fields of LED carrier, wafer, IC package carrier, etc. Future Prospects of Semiconductor Coating In response to the rising awareness of international environmental protection, major international manufacturers have demanded that the supply chain comply with the green manufacturing process. The high-level vacuum coating technology based on physical vapor deposition (PVD) can be applied to LED carriers, wafers and IC packaging. Compared with traditional hard anodizing and Teflon spraying processes, high-value products such as carrier plates have the characteristics of high yield, low pollution, high adhesion, recyclability and low-temperature processes. Dah Young can help manufacturers break through the technical threshold of surface modification to enhance the international competitiveness of the semiconductor industry. Dah Young has successively passed product application verification, and rushed to enter the high-end advanced semiconductor market.

Color on fine elegant metal watches DLC diamond-like carbon coating.
How are the colors of the colorful metal watches on the market made? The color of the metal watch is produced through the electroplating process. The early water electroplating technology used the principle of electrolysis to pass a direct current in the electroplating solution to deposit metal ions on the surface of the workpiece. The vacuum plating technology now more commonly used adopts the principle of Physical Vapor Deposition (PVD), injecting gas in a vacuum state to separate the target material into molecules, so that the conductive workpiece can adsorb the molecules to form a uniform and smooth film layer on the surface. The hardness of the coating, the anti-fouling of the surface, the durability of the performance, and the performance of vacuum plating have been greatly improved, and it is also more environmental friendly than electroplating. Coating processing of watches Generally speaking, physical vapor deposition (PVD) is divided into three types: Vacuum Evaporation, Sputtering, and Ion Plating. Among them, Ion Plating is considered to be the best for adhesion and durability. It cleans the surface of the workpiece in the form of sputtering, and then coats the surface of the workpiece using the characteristics of both vacuum evaporation and sputtering. The dissociated substances and gases adhere to the watch case. The film deposited by this process is very thin, which will not affect the thickness of the watch case. Japanese watch brands often emphasize that their use of IP technology is a good way to enhance the value and beauty of their watches. The mainstream of watch coating In recent years, the customer base of fine elegant watches has attracted the younger generations, and the design has become more and more sporty, with a visual presentation is of strength and energey. Many well-known brands such as Breitling, BALL Watch, VULCAIN, CHOPARD, etc. have launched diamond-like carbon watches. The color is mainly black, which is characterized by the advanced process of vacuum electroplating-Diamond-like carbon coating (DLC). This produces an amorphous carbon element close to diamond, which strengthens the protection of the watch surface. Recently, BVLGARI and G-SHOCK also released diamond-like carbon watches. Bvlgari Bvlgari Series. Sourc/Bvlgari Bvlgari's Bvlgari Bvlgari series watch, the entire watch is treated with DLC diamond-like carbon high wear-resistant coating, and the neutral pure black design is very stylish. The Octo Roma WorldTimer world time zone watch has two styles: a stainless steel blue face model and a DLC diamond-like carbon black face model. The DLC-like diamond carbon model has a 41 mm black sandblasted DLC-like diamond carbon treated stainless steel case. Octo Roma WorldTimer World time zone watch. Sourc/Bvlgari G-SHOCK uses Tokyo in the twilight as an image to convey the light and hustle and bustle of the city, and announces a new design in which purple and blue are interlaced from the case to the strap. Diamond-like carbon coating (DLC) is adopted on the spiral bottom cover, which will be more durable and will be on sale from September 2021. G-SHOCK GMW-B5000.  Sourc/CASIO The surface layer of the Diamond-Like Carbon Coating (DLC) has the characteristics of high hardness, corrosion resistance and low friction coefficient to meet the different demands of individuals and the varving environment conditions. Although diamond-like carbon coating (DLC) has a higher cost than the general PVD, it is being adopted for use in all watches from high quality brands to more common affordable brands. It can be seen that the excellent performance of the diamond-like carbon coating is recognized and increasingly popularized becoming more popular..
