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.

Regarding the "quotation" used at the forefront of sales activities: "Do we really need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving every process is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating the latest interpretations from the National Tax Agency's Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." - Items sent externally are "generally required to be preserved." - Items not sent externally have "no preservation obligation." 2. The sender's judgment: "Is it linked to a transaction?" 3. The recipient's judgment: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to achieve reliable "version management." ■ Summary

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
