By attached between the antenna and the back metal, forming a magnetic conduction channel, which can eliminate the interfere to antenna from metal (Or other sources of interference) , Enable the antenna to transmit a signal normally.
WLF15 series of magnetic separation chip products as a Shenzhen Penghui of many products in a very cost-effective material, favored by the majority of customers. This series of products is 0.3mm, 0.35mm, 0.4mm, 0.5mm, 0.6mm, 1.0mm (if customer usage is particularly large, other special thickness that can be customized), this product is widely used in RFID labels, smart card, PCB antenna, Flexible antenna, mobile phone shell, in the card packages and other products, can help customers solve environmental interference (common interference source is metal, It can also be a PCB, Components, etc.) and cause the product can not be used normally problems.
Penghui WLF15 series of magnetic diaphragm products is the magnetic conductivity of ferrite fine powder scattered in the environmental protection organic polymer binder, but also add some other additives, by the equipment to form a magnetic conductivity of ultra-thin rfid nfc antenna ferrite sheet material.
Production process: raw material inspection ingredients, crushing, rolling back, cutting and inspection packaging.
Raw material inspection: check the appearance, performance, density, status of raw materials, meet the inspection requirements before the ingredients.
RFID absorber material is a composite material with excellent absorbing ability to electromagnetic waves. RFID absorber material is a composite material formed by physically refining the alloy and treating it with a magnetic field to form a magnetic alloy with high magnetic permeability, and uniformly dispersing it in a polymer. The RFID system consists of an electronic tag or a non-contact smart card (such as a smart phone with a swipe card function) placed on an identified object and a device that issues instructions to the electronic tag and collects feedback information from the electronic tag. The device is also known as the RFID card reader or the reader is composed of two parts. In order to allow other devices to display or use these data, an interface with the RS232 protocol can generally be installed on the reader, so that information can be transmitted with external devices.
In the RFID identification process, because the electronic tag is susceptible to the interference of the metal eddy current close to it, the actual effective reading and writing distance of the tag is greatly shortened or no response occurs at all, resulting in a complete failure of data reading and writing. RFID absorber material has high magnetic permeability and can play the role of focusing magnetic flux, providing an effective solution to such interference problems.
RFID absorber material is a functional composite material that mainly absorbs electromagnetic waves. It can eliminate the back and forth reflection of electromagnetic waves in the shielding cavity, reduce the interference of clutter to its own equipment, and effectively prevent electromagnetic wave radiation from harassing and harming surrounding equipment and personnel. , is an advanced means of eliminating electromagnetic wave pollution.
In addition, the rfid absorber material with high magnetic permeability can play the role of focusing magnetic flux and provide an effective solution to the problem of RFID reading and writing interference.
