Poor adhesion of electroless plating on PET products
Fenómeno del problema
After electroless metal plating (copper, nickel) on the surface of PET products, the plating peels off and adhesion is unqualified.
Análisis de la causa
The PET surface is not sufficiently roughened (insufficient chemical etching) and the anchoring effect is poor; surface activation is not in place.
Solución
Use chromic acid-sulfuric acid etching or alkali etching for roughening; optimize sensitization and activation parameters; select formulations suitable for plastic electroless plating.
Conclusión clave
The key to PET electroless plating lies in surface roughening and activation treatment.
