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 Prolong copper foil be also used to reduce thin wire, high-layer multilayer circuit board coefficient of thermal expansion (TCE) and make " metal is sandwich On plate ".Japan also releases the new varieties of rolled copper foil in recent years, such as:High tenacity rolled copper foil, it is a kind of with low temperature crystallization characteristic Rolled copper foil.Since it is flexibility with high bending resistance, suitable on flexible board.Another kind is anaerobic rolled copper foil, characteristic That oxygen content only has 0.001%, tensile strength is high, available for require lead intensity high in TAB printed circuit board on and In the printed board of stereo set.
At present, rolled copper foil is generally used in flexible printed-circuit board, is the substrate for manufacturing flexibility printed circuit board (FPC) (FCCL) one of important materials.Flexibility coat copper plate (FCCL) refers in the flexible insulation material such as polyester film or Kapton The single or double of material by certain process, bonds together formed copper-clad plate with copper foil.FPC refers to use Wiring board made of FCCL is widely used in aerospace equipment, navigation equipment, aircraft instrument, military guidance system and hand Machine, digital camera, DV, vehicle satellite Fang are to Dinging in the electronic products such as Wei Zhuan Ge, LCD TV and laptop.
