Over the past 20 years, the development of the mobile phone mainly experienced five major stages:
1, the price is high, and only basic functionality.
2, volume decreases, and the price is relatively lower, more people can afford.
3, pay attention to the design, the design is more abundant.
4, more functional.
5, cycle shorter, require much less.
Pad printing technology in the application of the mobile phone industry also has experienced four stages: from the original single, double color printing mobile phone screen, lens, the incline to functional printing, to focus on decorative printing, special printing networks to appear in recent years.
A, mobile phone screen, lens single, double color printing
Mobile phone development initial period in the 1980 s, Ericsson, Motorala two mobile phone company monopoly market, production in Europe and the United States.The pad printing is used only for mobile phone keyboard, display, single or double color trademark.
With the development of the market, the increase of production, cell phone began to more requirements on printing "automation" system, even request with using computer CCD optical quality inspection system, equipped with mass production characteristics.At that time, a 16-bit turntable is very popular.
In the late 1990 s, mobile phone OEM base to Asian Japan, Korea, Malaysia, Taiwan and the mainland, because the local labor costs low, pad printing semi-automatic system requirements.
Because of lower labor costs, labor quality is not fully mature, relatively requires special Settings in order to reduce the labor quality caused by the poor.Rubber automatic cleaning device, for example, can reduce the number of irregular people stop cleaning glue head, at the same time can correct use of oil-water clean gum head misconception, because use oil-water clean plastic head, can greatly shorten the service life of rubber head.
Vacuum fixture can greatly reduce artificial placed caused during the printing product placement work.Far infrared drying device, greatly shorten the time of natural air drying printing pattern, also reduced the easy touch flowers "dry" probability of ink printing design.
Nokia once because of the dry solid processing after printing, the printing in 2000 hit 8210 type mobile phone shell, before/after adopted was first used in the pad printing "UV4 color method" (namely namely dry, create rich burnish feeling of quality of 3 d photo design).
YMCK4 color printing quality of market demand, has clearly show that;Mobile phone appearance, color, pattern design, etc, is taken seriously increasingly, and has become a part of fashion accessories.Uv requiring quick dry, showing the phone models exit the market faster and faster, more style, new design, but will soon be replaced by new style, so that each mobile phone production is much less than before.
Conventional pad printing system can not meet the production requirements, instead, fast zero adjustment system in 3 min to finish printing process converting from a to b, can satisfy the requirement of industry.
To achieve this purpose, the tone of zero adjustment system is fast, a thorough understanding of each project features, such as product material radian design color number of printing special effect of coordination with mobile phone designers the speed of the production process production color quantity production environment and so on.
Second, functional printing
To enter in the late 90 s, mobile phone production shift to domestic, concentrated production supply the global market, China mobile phone design is more tide, six color display color arrive, the screen is an arc bending.
New development of servo motor drive printing rubber head, provide powerful strength, the stability of the rubber head printing delay, can fully release ink color more strong.While traditional pneumatic system due to "restore gas" air cylinder and the influence of the central gas supply is not stable, can not achieve this function.
Along with the computer interface, PLC control precision fine-tuning to + / - 0.02 mm, more different printing setup data can store multiple projects.
Among them, the oil cup system is an indispensable part of, also is 3 min rapid transformation work of the foundation of zero adjustment system.Ink concentration tester is more close to provide scientific data to control the ink concentration, modern production management mode.
Phone models fashion diversity, same type production conversion much money every day, the transformation frequency comparison, this creates a new design of single fixture electronic servo motor drive pusher is more popular.
Understanding, individual characteristics of customers, production factors provide specially designed anti-static devices, to overcome the difficult dust-free workshop.
In the 90 s and 1980 s, has not been popular at the moment, the laser engraving technology, pad printing is applied in different colours on the print button to number, is already very popular.
Mention alternative application, must mention nearly 9 years of mobile phone pad printing application of the internal electronic components.Pad printing electronic components on the coding are not fresh.Due to the mobile phone industry increasingly fierce competition, nearly a decade of rapid rise south Korean mobile phone has been winning by function diversified chemical fiber thin the appearance of fine fashion.New phones appearance is thin, there is not enough space to accommodate the antenna line of intensive components on the PCB board arrangement.One large Korean mobile phone brand, has ventured into use successfully conductive pad printing ink will "accept the signal feature" lines printed on the PCB directly, instead of the current on the PCB antenna circuit arrangement.
Three, decorative printing
Into this century, the design of mobile phone and the printing effect more diversification, not just 6 color printing, pad printing different even blinking space metallic ink mirror ink, etc, to achieve the effect of designer requirements.
Pad printing level has been promoted to a higher level, for customers tailored inks, cooperate with servo motor printing characteristics, unique pad printing printing printed data model.Study how to use pad printing oil release ink ink between chemistry and the strength of the speed frequency with the physical response of plastic head, into a "unified solution".
The last five or six years due to fierce competition in the design of mobile phone surface arc shape design, considering the cost of scrap, the requirement of rapid transformation work every day elements, such as screen printing, IMD, even on IML there a lot of time.
Comprehensive previous pad printing production experience, the original mobile phone maker R&D designers, rapid response and service, comprehensive interface device with a combination of high-end printing equipment close clipping "all-round one-stop solution", immediately become customers to rely on cooperation partners.
At this level, the traditional printing technology has been unconsciously promote evolution "pad printing application of intellectual property rights" to a higher level.
In addition, in recent years is popular with unique hand touch following from surface feel paint coating, such as leather hand touch, soft non-slip rubber hand touch.Ink adhesion and pad printing equipment to cooperate once again faced with new challenges and requirements "to ensure good printing ink adhesion of pad printing ink pad printing and innovation.
Four, network business logo printing
As networks of different countries have sprung up in the global market are emerging, in the past simple sales to the customer after the original operators of production sales model evolution for sales networks, again by networks relies on the network for goods and services "cross-selling", which penetrated the market and expand the market share.Finally make the design of the original mobile phone business and network or a win-win situation.
Pad printing is not only for mobile phone brands printing trademark, trademark printing multiple networks around the world with different locations in the mobile phone shell.
As a mobile phone in printing enterprise, Kent has more than 20 years of experience in printing mobile phones, many well-known brand to provide a full range of printing solutions, Kent pad printing technology in the application of the mobile phone industry, would like to continue to work hard.
