Radio frequency tags (RFID) are a new force in the printing industry and an area that many entrepreneurs with long-term vision are most optimistic about. In order to meet the needs of different people, this article discusses in detail the causes and hazards of static electricity on radio frequency tags, as well as the methods for static electricity control experts and solution providers to protect radio frequency chips.
With the sudden rise of radio frequency identification technology, radio frequency tags (RFID) have also entered the paper product processing industry. Equipment suppliers want to become the number one provider of radio tag solutions in the industry. This has led to the rapid promotion of this technology throughout the industry. The scope of utilization of radio frequency tags is endless. Although it can bring countless opportunities to people, as the number of users increases, it will also bring a certain degree of challenges to people Liberians SugardaddyLiberians Sugardaddy.
Most label and trademark processors are asking: “What exactly is a radio frequency tag?” Wireless radio frequency technology is a method of remote storage and retrieval of data, and its application carrier is radio frequency tags. The tags contain antennas that receive and reflect wireless LR Escorts waves from the radio frequency transceiver. According to the different power supply methods of RF tags, they can be divided into two types, one is active RF tags and the other is passive RF tags. Active RF tags contain built-in batteries, while the latter do not. The built-in battery can emit clear electronic signals to distant places, but remote radio frequency tags are relatively larger and more expensive than passive radio frequency tags.
This is also where the “earthquake” occurred. Radio frequency tags are electronic devices. When people designed them, they did not take into account the harsh surrounding conditions of the paper products processing industry. I can’t say how familiar the paper product processing plant is with electronic components, but I can assure you that there is no place in the paper product processing plant suitable for storing unprotected chips. Indeed, as mentioned above, there are various types of chips, and some of them are more resistant to electrostatic interference. Despite this, there are still many documents recording the damage caused by electrostatic discharge to RF chips. case. This kind of damage usually leads to the quality of product tools declining in a short period of time, and more seriously, it may cause the failure of the radio frequency chip.
Question
In the process of packaging and paper product processing, static electricity is a common problem that needs to be discussed. For example: slitting, printing and coating processes are all related to static electricity.
Static charges are generated by materials coming into contact and separating as they pass through different stages of production and processing. When materials come into contact and separate from each other, the friction between them (triboelectric charging) creates surface charges, or static charges. By definition, static charge is the residual charge caused by charge imbalance. This charge usually occurs on insulating materials, such as film or coated paper, and may also occur on conductive surfaces that are isolated from the ground. This is an important point because many material suppliers claim that their new antistatic material Liberians Escort can protect RF chips from static electricity The disturbance of charge. Unfortunately, their statement is not entirely correct, because static charges can be transferred to conductive objects that are isolated from the air. Once such a conductive object (such as a radio frequency chip) is close to the ground, the transfer of charge can cause damage to the object. Contact and separation of material surfaces
When two surfaces come into contact, the charges between them are rearranged. And when the two profiles separate, electronic communication occurs. One surface will give up its electrons, then its charge balance will be broken and it will be in a positive state, while the electrons of the other surface will LR Escortswill be redundant or in a negatively charged condition. The materials involved and the attraction and pressure generated by their contact and separationLiberia Sugar will all affect the amount of chargeLiberia Sugar has had a huge Liberians Sugardaddy impact. To understand the charge characteristics of a material, you must consider its ranking in the triboelectric sequence. The relative position of materials in the triboelectric sequence determines the magnitude and polarity of the charges generated when materials are in direct contact and separation. The further apart the data are in the center of this sequence, the greater the number of charges generated between them. Moreover, it is easier for the material at the top of the table to capture positive charges when it comes into contact with the material at the bottom of the table.
Static electricity makes the problem more complicated because it increases gradually. Each time the material comes into contact with another surface, the charge it carries increases. This is most evident when materials come into contact with multiple surfaces, This is what the web tightening roller does during web processing. The most important thing is to realize that the control of these charges should be considered as part of the plan to keep the radio frequency tag safe during the birth process Liberians SugardaddyDepartment. Typical areas where it is not difficult to generate a large amount of electric charge are: web transfer system – unwinding device, clamping roller, accumulator, paper guide roller with insulating sleeve, corona treatment device, gravure printing roller , automatic rewinding device, independent packaging or cover device, etc.
Liberians Sugardaddy Electronic Equipment
The introduction of radio frequency chips into the packaging/paper product processing field has changed everything . Because these tiny circuits cannot withstand the influence of stray voltages. They may be damaged for a variety of reasons, the most damaging of which are:
* Damage caused by direct discharge of static electricity. When a charged Liberians Escort object or person comes into contact with the radio frequency chip, some of the stored charge will be transferred or released to the radio frequency chip. Or it can be transferred to the ground through radio frequency chips. The charge transferred to the RF chip contains enough energy to damage the circuitry on the chip. The transfer of energy is mainly reflected in heat, and this heat will cause one or more layers of material inside the device to melt.
* When conductive objects isolated from the ground are exposed to an electrostatic field, static electricity may also occur. Under these circumstances, the isolated conductor (radio frequency chip) will be polarized in the electric field, and if the radio frequency chip comes into contact with the ground quickly under these circumstances, it will generate a current in pursuit of charge balance. The result of this is that when the electric field is removed, the radio frequency chip will generate charges of the opposite polarity and be in a charged state. Then when it comes into contact with the ground for the second time, a direct discharge will occur.
* The impact of electromagnetic interference on radio frequency chips is also Liberia Sugar very dangerous. The so-called electromagnetic interference is the overLR Escorts voltage that we often refer to in the electronics industry. If the radio frequency chip encounters an instantaneous power, voltage or temporary power that exceeds its circuit isolation capability, damage will occur.
A failed analysis report made by the electronic industry department shows that the chance of static electricity causing direct or catastrophic damage to radio frequency chips is only 10%; in 9Liberians Escort 0% of the time, it will cause potential errors that will eventually lead to equipment failure. I think this potential problem is very similar to the cracks in the Liberia Sugar Daddy glass. The glass may still be usable, but each time it is pressed, the cracks will become larger until the glass is eventually broken. The question is, when will the radio frequency tags become ineffective? What’s more, people have no way to fix these potential problems during the birth process; you can check them at your own testing station. The RF chip undergoes initial testing and it works fine, but when your customer tests it, it doesn’t work properly. At this point, one of the biggest issues facing manufacturers is the integrity of the chips. Profit rate is not what they really need, they need to provide customers with 100% reliable products.
Solution
The most active radio frequency product in today’s paper processing field is the pressure-sensitive LR Escorts label. Now, its production process has become very slow, running at only 50 to 150 fpm (feet per minute) as the chip is transferred from the web holder to the substrate. Some manufacturers will embed the production process of radio frequency chips into their Liberia Sugar paper product processing process, or there may be some small labels The processing plant will transfer some post-assembled RF chips to the printed labels. In both cases, whether the extraction equipment they use is a very mature brand-name product or a processing machine assembled by themselves, it will have a great impact on electrostatic control.
Liberians Sugardaddy To control the static electricity on the RF chip, you need to use an active Liberians Sugardaddy Static eliminator, it can maintain a relative ionization balance, and can also neutralize the charge generated during your specific use (speed, material type, etc.) . The ionization balance of the static eliminator (the balance of positive and negative charges) is very important, because the glueImprinting voltage can damage some radio frequency chips. Although so far there is no industry standard that stipulates the voltage value at which radio frequency chips can be protected from static interference, many tag manufacturers recommend that people keep the charge level at about 500 volts. For example, when chips are put into p-s tag assembly lines, they become more robust, but many plug-in equipment manufacturers recommend that we use about 1,500 volts Liberians Escort, controls the electrostatic charge when the label is inserted into the label substrate. In any case, the ionization balance brought about by a well-designed ionizer can quickly reduce the number of static charges to a level that does not damage the radio frequency chip.
Do not use passive static eliminators (metal foil or conductive wire) to protect RF chips. Although passive static cancellers can dissipate some static charges in some industrial environments, such ionizers are very dangerous for RF devices because they can only reduce static charges to the point where ionization occurs. on the voltage value. The risk of using this device is that the threshold voltage of the passive static cancellerLiberians Escort is usually higher than what most RF chips can withstand voltage value.
Among active electrostatic ionization products, the most effective one has been proven to be the extended static bar. They neutralize reels that move at high speeds Liberia Sugar Daddy (2,000 to 2,500 fpm) https://liberia-sugar.com/”>Liberia Sugar Daddy static electricity on the paper, and its removal interval is very suitable, can LR Escortscan make ions better mixed to maintain a better ion balance Liberians Escort. At the same time, it can also keep the radio frequency chip at a relatively safe distance from the high-intensity electric field next to the Liberia Sugar Daddy emitter. When the electrostatic bar reaches the transfer point (pull-out point), it can successfully neutralize the electrostatic charge on the label paper (label printing material with adhesive and backing paper), paper or film. so-called transferThe point (pull-out point) is where the RF chip is exposed. At the same time, this is also the most vulnerable place and the least likely to be damaged by static electricity. Therefore, our concept of using electrostatic rods is to ensure the electrostatic balance in this area at all times.
The transfer (removal) operation is very critical, because during this process, the RF chip is very likely to generate charges due to contact or separation. People usually use ionization equipment designed specifically for electronic applications in this regard, ionization blowers or air-assisted ionizers in key areas, because the ion balancing characteristics of these equipment are more conducive to the sensitivity of the conductive chip, and they also have the ability to transfer ions Transported into a narrow mechanical space.
The electrostatic rod can be used at the switching point where the RF chip is inserted, to control the web Liberians Escort tight paper roller or additional Static electricity generated during processing (for example: die cutting). For label processing plants, the removal process of cutting materials after die-cutting is also a well-known area for static electricity generation, and it usually generates static electricity at a voltage of 20,000 or 30,000 volts. People must control LR Escorts these charges to protect the radio frequency chip and reduce the accumulation of energy on the paper roller when the web is rewinding. The number of charges. The large amount of electrostatic charge on the paper roller is a huge threat to the radio frequency chip installed on the label paper. The reason has been mentioned earlier, and I will not say more about it here.
Summary
Radio frequency technology brings bright prospects to the packaging industry, and it will bring a large number of business opportunities to this industryLiberia Sugar encounter, and, with the large-scale production of radio frequency tags on wider and higher-speed printing presses, electrostatic control has become an increasingly important issue. As long as you can control the static electricity, Liberia Sugar Daddy will be yours in the future.
