Application of fiber laser marking in IC card industry
Smart card (Smart card or IC Card), also known as smart card, smart card, integrated circuit card and IC card, refers to a type of portable card plastic that is pasted or embedded with integrated circuit chips. It is formed by embedding an integrated circuit chip with a microprocessor and a large-capacity memory on a plastic substrate, and its appearance is very similar to that of an ordinary credit card. Smart cards came into being with the development of semiconductor technology and the increasing demands of society for information security and storage capacity. Today, smart cards have become a new star in the information society. Common smart cards include telephone IC cards, identity IC cards, and some transportation tickets and memory cards.
China's IC card industry is developing at an alarming rate, especially in the past two years, China's annual card issuance volume has exceeded 100 million, and the application fields of IC cards are in telecommunications, social security, second-generation ID cards, banks, taxation, public transportation, Expressway card, fuel card and many other industries. With the expansion of the application scale of IC cards, the packaging, printing and marking business of cards has developed into industrial production.
With the development of the IC card industry and the increase in the requirements for card making, the printing method of cards has gradually shifted from ink printing and thermal transfer to laser printing.
Comparison of fiber laser marking and other card manufacturing technologies
Laser marking has many advantages over other thermal transfer technologies such as permanent marking and no consumables. It is replacing traditional card manufacturing technology in more and more application fields. In addition, due to the rapid development of laser technology and the market demand for laser products with high output power, small size and low maintenance, the laser module integrated in the card issuer has been printed from the lamp pump marking machine and the diode pump. The marking machine gradually developed into a fiber laser marking machine.
The fiber laser marking machine uses a computer-controlled laser to etch characters, patterns, or barcodes on the surface of the card. It has the advantages of more exquisite marking effects, no consumables, and no maintenance.

Marking effect
High requirements for materials, there will be unclear printing, missed printing phenomenon, can be erased.
The material is slightly different, and the printing effect will not change much. There will be no unclear or missing words, and it cannot be erased.
stability
Unclear or missing words need to be manually erased and retyped, which increases the probability of errors and labor costs.
Once the machine debugging is stable, the possibility of error is zero.
Maintenance
Print head failure is high.
The life of the laser tube is up to 100,000 hours, and the whole machine is maintenance-free for 10 years.
Consumables cost
Including accessories such as consumable print heads, manual maintenance, etc., under full load conditions, the maintenance cost is 50,000 / year.
The life of the laser tube is up to 100,000 hours, depreciation for 15 years, no consumables for life.

Materials for fiber laser marking applications
Fiber laser marking can mark a wide range of materials, including PVC, PC, high temperature plastics, Teslin, ABS, PET, PET-G, PET-F and other materials. [next]
Application examples of fiber laser marking in IC card industry
Fiber laser marking is mainly used in the mobile phone card marking of the telecommunications industry and the marking of IC cards in urban utilities. Its specific application fields include public transportation, rental, rail transit (subway), water supply, heating, gas, garden landscape, The digital community, road and bridge toll collection, parking lot management and other very broad fields. The following lists some specific application fields and examples of fiber laser marking.
1. Telecom industry
(1) SIM card

Figure 4 shows the marking effect on a mobile phone card with a fiber laser marking machine with a power of 30W. Mobile phone card laser marking content is mainly 128,39 bar codes and numbers. Generally, there are certain requirements for the readability level of bar codes. Use 30W fiber laser marking machine to mark, the marking time used for each card is within 1s (depending on the material). Of course, for the same marking content, the higher the average output power of the laser, the shorter the time required for marking.

The application of smart cards has covered many fields of today's social economy. According to a survey by international professional institutions, billions of smart cards are currently being used internationally, and the application of smart cards in China's large and medium-sized cities is also increasingly popular. In some places, the local government even regards the construction of the city card or citizen card project as a kind of "people's heart project", which has indeed played a very good effect in real life and has played a positive role in promoting the construction of an overall harmonious society. Promotion. Therefore, with the development of the smart card industry, the application of laser technology in it will also become more and more extensive.
