What this resource is for
Use this page to organize an initial engineering or procurement review for copper oxide powder (CuO) used in PCB acid-copper electroplating. It does not replace a process trial, a batch Certificate of Analysis (COA), the Safety Data Sheet (SDS), or an agreed purchase specification.
Published application context
The product page positions electronic-grade CuO as a controlled copper source for PCB acid-copper electroplating systems that use insoluble anodes. The same published page also lists high-end PCB manufacturing, semiconductor packaging boards, PET composite copper foil, and silicone-monomer-related applications. Confirm the intended process and grade during technical alignment.
Published specification fields to review
The following are published electronic-grade specification limits on the product page. They are not a substitute for the applicable batch COA or a customer-approved specification.
| Field | Published electronic-grade specification |
|---|---|
| CuO | ≥ 99.00% |
| Cl | ≤ 0.0015% |
| Pb | ≤ 0.0005% |
| Na | ≤ 0.0030% |
| Mg | ≤ 0.0010% |
| Mn | ≤ 0.0005% |
| Fe | ≤ 0.0010% |
| Ni | ≤ 0.0010% |
| Zn | ≤ 0.0010% |
| Ca | ≤ 0.0010% |
| Acid-insoluble matter | ≤ 0.003% |
| Dissolution rate in acid | ≤ 30 s |
Supplier qualification checklist
Before issuing a purchase order or approving a trial, align the following points with the supplier and your process team.
- 1Confirm the end use, bath chemistry, and whether the process uses insoluble anodes.
- 2Compare CuO assay, impurity limits, acid-insoluble matter, and acid-dissolution requirements with your internal acceptance criteria.
- 3Request the applicable batch COA rather than relying on a representative result alone.
- 4Review the SDS for handling, storage, and transport requirements before sample or production use.
- 5Confirm particle-size evidence, packaging format, document language, and any required third-party inspection before release.
Published CuO documentation
These files are available from the product and downloads pages. Review the document language, date, and whether it applies to the batch under evaluation.
Certificate of Analysis (COA)
Published composition and impurity inspection record for the available document set.
Safety Data Sheet (SDS)
Published hazard, handling, storage, and transport information.
SGS Test Report
Published third-party test documentation for the available document set.
Particle Size Report
Published particle-size evidence for engineering review.
Representative inspection values shown elsewhere on the product page are published reference information. Final supply remains subject to the applicable batch documentation and the agreed specification.
