First, Screen printing, mostly use automatic or semi-automatic printing machine, and the method of feed and output feed is on the axis. The most important step is not to shut down, so rfid antenna has to be produced in a clean environment. An automatic inking system and bilateral normalization ink plate (ink every scrape India graphical Central time, will be extended to the edge of the ink classified for the production uninterrupted, it is best to be installed at the top of the screen to be back to Mexico after squeegee again), to prevent ink expansion extending to the edge, resulting in solvent evaporation to change its viscosity. The aim to install an automatic inking system is to maintain a consistent ink viscosity, to maintain the squeegee uniformity and consistency. In addition, the hardness of the squeegee, running speed, screen printing squeegee angle, the net margin parameter cannot be changed after being confirmed.
Second, curing (drying)
First, in the step of gravure resist ink, and some plants gravure after both UV curing have IR cured, due to the ink used requires both UV curing also subjected to IR and solidified. There are two reasons for the wrong action: first, a waste of energy; second, solvent evaporation pollute the environment; third, cumbersome processing; fourth, cause trouble for the procedure (faded ink through nearly two years of investigation difficult); fifth, the number of waste increase. After our efforts, have been removed in the plant the IR curing systems, greatly improved their production outlook, not only can save energy, but also reduce costs, and also to increase the yield. This high infrared technology of china antenna can be a good solution to curing the conductive paste production bottlenecks.
Third, deviation in the rolling up: the winding is the axis of the shaft of the transmission, so the precision of the winding is very important, in the gravure printing (printed resist ink conductive paste), the accuracy of the winding also affect the coincidence of the two-sided graphics degrees, gravure printing machine used in modern production line transmission accuracy can be basically guaranteed. But with the increases of the winding diameter, the manufacturers are using electronic calibrator control deviation which can be controlled between 0.3 ~ 0.8 mm. But it should be noted that the etching lines or curing line deviation due to the length of the reasons may be more than the above range, some operator ignores the deviation of the problems in this step, severe will affect the quality of the etching, and de-inking effect.
