Printed Circuit Boards CHEMICAL

Flexible and rigid-flex printed circuit boards are absolutely essential components in mobile telephones, digital cameras, and notebook computers. Advances in these circuit boards are being made on a daily basis, and strategies are being sought to eliminate connection reliability and other worrisome elements in manufacture. UYEMURA is responding to its customers’ needs in this area by using its extensive know-how to develop chemical product solutions.


Semiconductor Chemical

Through exploiting the strong points of plating, UYEMURA provides a wide range of chemicals for use in processing semiconductor wafers, including chemicals developed for use in UBM (Under Bump Metallization)


Electroless Nickel Chemical

Maintaining the accuracy of components in precision instruments is vital, and the corrosion, abrasion, and magnetization that occur during long-term use are currently major problems, Electroless nickel plating plays a major role in solving these problems, as products utilizing this particular surface finish have a uniform plating thickness, thus maintaining an even surface, and are highly resistant to corrosion, abrasion and magnetization


HDD Chemical

Hard disks are currently used in a large variety of information systems, including personal computers, HDD recorders, set top boxes, and car navigation systems. In order to increase hard disk capacity, properties such as smoothness, evenness, faultlessness, and non-magnetism are being sought in the substrate layer of aluminum magnetic disks. Purity is also crucial, and it is vital to ensure that even dust particles smaller than those found in tobacco smoke do not enter the disk’s substrate layer. Specialized electroless nickel plating is truly indispensable in the formation of these kinds of substrate layers.


Electrolytic Plating

Composite plating:
Use specialized plating processes containing polytetrafluoroethylene (PTFE) particles, with varying amounts of PTFE, provides various unique properties in the plated finish, such as abrasion resistance, water repellency, nonviscosity, and lubricity. These properties are currently being put to use in many different types of machine components.

Heavy metal-free plating:
Environmental regulations are growing tighter, especially in areas such as Europe, and soil contamination due to waste disposal is now a major issue. Furthermore, regulations concerning harmful heavy metals contained within manufactured goods themselves are now being strictly implemented. UYEMURA has developed an entire family of plating chemical products that do not contain harmful heavy metals, and they are now being used by many of our customers worldwide.



Electroless nickel plating is used in a great many industries. In the plating process, it is very important to have chemical solution control management, and it is essential to have an automated chemical control system. UYEMURA has developed automated plating chemical solution control systems that are easy to operate and are specialized for use in electroless nickel plating, and these units are now commercially available.
