Pre-lamination treatment for multilayer substrates (alternative to black oxide treatment)

Environment-friendly process developed as an alternative to black oxide treatment.

MEC V-Bond

BO-7790V

This H2SO4-H2O2 type microetching agent is developed as an alternative to black oxide treatment and can improve the adhesion of copper to FR-4, as well as high Tg or halogen-free materials.

Features of MEC V-Bond BO-7790V

  • Can create a surface topography with high reflow-resistance.
  • Performs etching on copper surfaces to create a roughened topography (anchor effect) while forming an organic copper film on the surface (primer effect).
  • Helps to achieve high adhesion to FR-4, as well as high Tg or halogen-free materials.
