Photosensitive-ink, the preparation method the invention further relates to the photosensitive-ink and its application and printing in FPC is printed
The FPC of the photosensitive-ink.
Background technology
FPC can provide excellent electric conductivity, can be with free bend, winding, folding, also subject to millions of
Secondary dynamic bending according to space layout any arrangement of requirement, and can arbitrarily be moved and stretch without damaging wire in three dimensions
Contracting, so as to reach the integration of components and parts assembling and wire connection, therefore can meet smaller and more high-density installation setting
Meter needs, it helps reduce assembling procedure and enhancing reliability, flexible PCB is to meet miniaturization of electronic products and movement
It is required that only solution.FPC has three kinds of single-sided flexible plate, double-faced flexible plate and multi-layer flexible sheet, first during preparation
First need it is etched be made copper circuit, be coated with insulate solder mask, coating insulation solder mask more use silk screening and wet film method, point
Cai Yong not flexible solder mask and photoimageable solder resist ink.Because FPC needs to bend, fold and move, this is accomplished by
Flexible solder mask adapts to this kind of requirement, therefore the matrix resin of ink is needed with fabulous pliability, to ensure in 25 week
After phase bending, the soldering-resistance layer of solidification do not show separations, rupture or from base material, the phenomenon of wire higher slice.Therefore, flexible wires
Road plate is very high to flexible solder mask and photoimageable solder resist ink requirements, and general ink is extremely difficult to require.
