Semiconductor

The popularization and application of semiconductor technology plays an important role in the evolution of the information age. Desktop computers, the Internet, tablet computers, mobile phones, automotive information products, and pocket medical products for home use all rely on semiconductor technology and are increasingly becoming an important part of people's lives. The main carrier of semiconductor products is silicon wafers, on which integrated circuits are made as required. Because of the higher requirements for the operation speed of integrated circuits, and the product volume should be as thin and short as possible, people use the electroplating method to solve the internal electrical interconnection requirements of integrated circuits. Since the 1990s, the company has been engaged in the research, development and manufacture of anode and main salt products for semiconductor electroplating. Our high quality products are widely used and highly recognized by our customers in the semiconductor industry.

Conductive cloth

With the development of electronic science and technology, microwave technology has been widely used in the fields of national defense, scientific research, communication, display and medical treatment. But microwaves can interfere with the normal operation of electronic equipment and harm human health. Conductive cloth can play a good role in shielding microwave, so its application scope is more and more wide. There are two main processes of conductive cloth electroplating: one is the traditional chemical copper precipitation, then copper plating with copper pyrophosphate system, and finally nickel plating; Another process route is to sputter a layer of metal copper, then copper pyrophosphate system plating copper, and finally nickel plating. Electroplating conductive cloth requires low coating stress, good softness, as the industry quality benchmark, the high quality electroplating materials produced by Younai can well meet the requirements of conductive cloth customers.

NdFeB

Ndfeb permanent magnet materials have been widely used in modern industry and electronic technology because of its high magnetic energy product, coercive force and high energy density. So that instruments, electroacoustic motor, magnetic separation magnetization and other equipment miniaturization, lightweight, thin become possible. High-end NdFeb magnetic materials have high anticorrosion requirements, and nickel plating process is usually used. Copper pyrophosphate is usually used to create a layer of copper for thickening between the pre-plated nickel and the bright nickel coating. The potassium pyrophosphate produced by Younai has strong complexing ability, high purity and stable quality. With copper pyrophosphate and pure copper anode without oxygen produced by Younai, it can effectively ensure the quality of customers' products and reduce customers' production costs.

Cavity

Aluminum cavities are widely used in electronics, communications, electrical appliances and other industries. In order to shield the signal, the inside of the aluminum cavity is plated with silver. Because aluminum is a reactive metal, its expansion coefficient is very different from that of silver, and the size of the product is large, the shape is complex, and the inner cavity is deep, which causes great difficulties to electroplating silver. This problem can be solved by electroplating a layer of copper as a buffer between the metals aluminum and silver using a process called copper cyanide plating or copper pyrophosphate. Compared with traditional electrolytic copper, the anodic copper produced by YouNA has obvious quality advantages with high purity, less impurity content and delicate lattice. The stability of the process can be improved effectively when the copper pyrophosphate and potassium pyrophosphate are used together.

Lead frame

Lead frame as a carrier of integrated circuit chips, is a kind of with the aid of bonding material (wire, aluminum wire, copper wire) for chip internal circuit outside the terminal and the electrical connection in the lead, the formation of the electric circuits of the key parts, which serve as the bridge between the external and wire connection, the vast majority of semiconductor integrated block you need to use lead frame, It is an important basic material in the electronic information industry. Lead FRAME PLATING IS A SPECIAL SURFACE TREATMENT ON THE MOUNTING/BONDING AREA (LEAD PINS AND ISLETS) OF THE LEAD FRAME, WHICH is mainly used to ENSURE THE MOUNTING/bonding performance in the packaging process and to make the chip and welding wire form good diffusion welding with the lead frame. Generally, the process of preplating copper and then nickel and finally silver or gold is adopted. Compared with traditional electrolytic copper, the anodes of oxygen free copper have obvious quality advantages with high purity, less impurity content and fine lattice. With excellent resistance of copper pyrophosphate and potassium pyrophosphate, can effectively ensure the quality of products. The excellent resistance of nickel sulfamate is MADE OF high QUALITY NICKEL as RAW material and produced by advanced technology of the United States, which ensures the stability of the product and the lowest internal stress of electroplated nickel layer in the whole industry.

Connector

Terminal connector plating has two main roles: one is to protect the substrate from corrosion; The other is to optimize the surface performance, establish and maintain the contact interface between terminals. Its electroplating process generally chooses nickel layer as the base, and then carries on the surface functional electroplating (such as tin, silver, gold, etc.). Low stress metal coating can be produced by nickel sulfamate system. Therefore, nickel sulfamate plating system is widely used in terminal connector field. Excellent resistance to nickel sulfamate selection of high quality metal nickel raw materials, and the use of the United States advanced technology for production, the product has high purity and good stability. Selection of optimal resistance to nickel sulfenate solution electroplating can produce very low stress, delicate and shiny lattice metal coating.
