MEC V-Bond BO-7790V Flood-immersion BO-7710V Spray
Features of MEC V-Bond
- MEC V-Bond is a H2SO4-H2O2 microetching agents which is devoloped as alternative to black oxide treatment to reduce enviroment impact.
- Performs etching on copper surfaces to create a roughened topography (anchor effect) while forming an organic copper film on the surface (primer effect) to achive the high adhension and heat resistance of resin.
- Helps to achieve high adhesion to FR-4, as well as high Tg or halogen-free materials.
- We can offer the most suitable chemical solution according to the customer's application, such as BO-7790V for flood-immersion treatment and BO- 7710V for spray treatment.
