Process for the functional oxidation of inner-layers for printed circuit boards. |
|
Reliable and low cost black oxide process for Multi-Layer manufacturing |
|
By varying the concentrations of part A and part B together with the process parameters either black or brown oxide can be formed. |
|
Controlled crystal growth |
|
Optional Post-Dip for highest acid resistance The formation of pink ring is largely minimized by this Oxidation Post-Dip. |
|
Suitable for vertical and horizontal techniques |
