A comprehensive unveiling of new plating chemicals related to semiconductors and environmental compliance!

Okuno Pharmaceutical Industry has established a final surface treatment process that forms a void-free and uniform plating film on the circuit surface.

Okuno Pharmaceutical Industry has established a final surface treatment process that forms a void-free and uniform plating film on circuit surfaces. The "ICP-COA process" is a low film thickness Ni-P/Au plating process that utilizes a reducing cobalt catalyst. This process consists of a reducing cobalt catalyst solution "ICP Accel COA" and an electroless Ni-P plating for cobalt catalysts "ICP Nicoron COA-GM." In conventional processes using palladium, the copper material corrodes during the catalyst application step, leading to the formation of voids between the copper material and the plating film, which has been a challenge. In this process, a uniform catalyst film can be formed through reduction deposition, enabling the reduction of the film thickness of electroless nickel plating (electroless nickel plating thickness: conventional process: 3.0µm, ICP-COA process: 0.5µm). Furthermore, since a void-free and well-covered film can be obtained, it is possible to reduce the film thickness of electroless Ni plating without compromising solder joint reliability.

Copper sulfate plating additive for high aspect ratio substrates for package substrates "Topluchina HLS"

This is the latest plating technology for semiconductor package substrates (IC substrates). Currently, electronic devices such as smartphones, computers, and servers are becoming more high-performance, leading to a reduction in the diameter of through-holes that electrically connect the layers of printed circuit boards, as well as a decrease in pitch. As a result, there is an advancement in the high aspect ratio and high density of through-holes. We have newly developed a copper sulfate plating additive for high aspect ratio substrates that can accommodate both soluble and insoluble anodes, aimed at improving the productivity and quality stability of printed circuit board production. This product excels in depositability within through-holes and vias, achieving high throwing power across a wide range of current densities.

There is a track record of maintaining a precipitation rate of approximately 20 μm/h for more than 10 turns since the construction of the bath. It is possible to reduce the amount of waste liquid and achieve cost reduction.

Electroless nickel-phosphorus plating tends to have a decreased deposition rate as the number of turns progresses, and it is common to refresh the bath after 5 to 6 turns. Since updating the bath requires significant effort and time, there is a strong demand for longer-lasting electroless nickel solutions. In response, our company has optimized the balance of chelating agent combinations and concentrations to develop an electroless nickel plating solution that experiences minimal reduction in deposition rate for over 10 turns from the start of the bath. The development of this product can enhance productivity, reduce waste liquid volume and energy costs, and contribute to lowering environmental impact. 【Top Nicoron LLM-LF】 - There is little change in deposition rate and phosphorus content due to bath aging. - Usable for up to 20 turns. - Low film stress with minimal changes in stress due to continuous use.

SPACECOOL Co., Ltd. will exhibit at the 12th Heat Countermeasure Exhibition, a specialized trade show focused on solving heat-related issues, to be held at Tokyo Big Sight from July 15 (Wednesday) to July 17 (Friday), 2026. At this exhibition, we will showcase products from the "SPACECOOL Consumer Products Lab.," including the "SPACECOOL Umbrella Type 2," which will be launched in June 2026, as well as products currently under development. The "SPACECOOL Fabric Type 2" used in the exhibited products significantly suppresses the intrusion of heat from sunlight and promotes heat dissipation by radiating the heat transferred to the umbrella as infrared rays into space. The "SPACECOOL Umbrella Type 2" achieves high light-blocking and UV shielding performance, with a heat shielding rate of 80% (in the case of silver). We invite you to visit our booth when you come to the venue. Exhibition Overview: Dates: July 15 (Wednesday) to July 17 (Friday), 2026, 10:00 AM to 5:00 PM (until 4:00 PM on the final day) Venue: Tokyo Big Sight, East Hall 7 Our Booth Number: 7-ZF13 *Advance registration is required for attendance (free of charge).

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
