Technical field
The present invention relates to technical field of ink more particularly to a kind of high adhesion force black matte silk-screens for copper foil base material
Ink and preparation method thereof.
Background technology
Copper foil can be divided into two major class of rolled copper foil and electrolytic copper foil according to different preparation methods.
Electrolytic copper foil is that copper first is made solution through dissolving, then in dedicated electrolysis installation by copper sulfate electrolyte straight
Under the action of galvanic electricity, electro-deposition and former foil is made, then according to require to be surface-treated former foil, refractory layer processing and oxygen
The a series of surface treatments such as change processing.
Rolled copper foil is by rolling being repeated several times and manufactured former foil, according to requiring to carry out roughening treatment by copper coin.By
In the limitation of rolled copper foil processing technology, width is difficult the requirement for meeting rigid copper-clad plate, so rolled copper foil is covered rigidly
Using few on copper foil plate.Since rolled copper foil folding resistance and coefficient of elasticity are more than electrolytic copper foil, therefore suitable for flexible copper clad foil
On plate.Its copper purity reaches as high as 99.9%, more smooth than electrolytic copper foil on hair side higher than electrolytic copper foil (highest 99.8%),
These are all conducive to the quick transmission of electric signal.Therefore, it is external in recent years in high-frequency high-speed signal transmission, thin wire printed board
On base material, using rolled copper foil.Pcb substrate of the rolled copper foil on stereo set uses, and can also improve acoustical quality.Pressure
