Description
Technical Field
The invention relates to the technical field of character ink for a PCB (printed circuit board), in particular to a PCB jet printing character ink composition and a preparation method thereof.
Background
In the PCB production flow, the solder mask process is usually carried out and then the character printing process is carried out, and characters are directly printed on the solder mask surface in an ink-jet mode. The solder resist process comprises: preprocessing → printing → prebaking → negative film exposure → developing → character transfer printing. The ink-jet character printing process includes: ink-jet of characters on the surface A + UV curing → ink-jet of characters on the surface B + UV curing → post-baking curing → turn-down process.
The main principle of the ink-jet printing technique for printing characters on printed circuit board is that the special character ink is jet-printed on the circuit board according to the file data designed by CAD (computer aided design) or CAM (computer aided manufacturing), and the process of character technology is completed by UV irradiation to implement instant curing. The traditional screen printing process needs 13 processes such as screen stretching, printing and baking, and the ink-jet printing technology only needs 4 processes such as ink-jet printing and baking. The technology for printing the PCB characters by ink jet saves the process and equipment for manufacturing the screen printing plate, saves the field and the space, reduces the consumption of ink, improves the productivity, reduces the environmental pollution and reduces the cost.
The UV curing type character ink-jet ink consists of a reactive oligomer, a reactive monomer, a photoinitiator, an additive and a dispersant. The current commercial UV curing type character ink-jet ink has the conditions of surface drying and poor adhesive force after UV curing, and jet printing characters are easily scratched or fall off from a solder mask in the process of transferring to the next working procedure.
