Surface pretreatment and drop spreading control on multi component surfaces

摘要: Methods, systems and produced printed substrates are provided, which include composed of one or more materials treated by an intermediate layer for normalizing surface energies a digitally formulation adapted to the normalized energies. Surface energy normalization may be carried out physical processes selective chemical processes. In example, self-assembled monolayer is applied circuit board control ink jet dots reducing copper improve adhesion. The binds via α group selectively covalently on hydrophobic ω solder mask that board. participates in solidification process ink.
