High adhesion even to difficult-to-plate materials
Plating primer paint “Metalloid”
What is a “metalloid”?
Plating primer that enables high adhesion plating to various substrates (resin, ceramic, glass, etc.)
◆Features of “Metalloid”
・No etching required, smooth plating film with good adhesion.
・High adhesion to difficult-to-plate materials such as glass.
・Short process with little waste liquid, printable.
・Coating film is thin (several tens to several hundreds of nm) and has good transparency.
◆”Metalloid” Cu plating film and peel strength of each substrate.
| Substrate | Peel strength |
|---|---|
| ABS COP PP Polycarbonate Nylon Polyimide Elastomer | 10 N/cm |
| Glass Tempered Glass Quartz Glass Alumina | 8 N/cm |
| PET LCP PTFE Si Wafer Polyphenylene Ether (PPE) Polyphenylene Sulfide (PPS) | 6 N/cm |
| Epoxy SiN SiC | 4 N/cm |
Application examples of “Metalloid”
◆Glass Interposer (TGV)
〇 Low temperature process (120℃).
〇 High adhesion and coating ability to TGV.
◆Roll-to-roll plating process for 5G
〇 Thin (≦2 μm) Cu film can be formed.
〇 Plating interface is smooth → low transmission loss
◆High-definition Cu patterning
〇 High-definition Cu patterns can be formed in a short process.
◆Plating on fibers and powders
〇 Plating on fibers, nonwoven fabrics, and powders is also possible.
