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.

Appearance and structure of Penghui WLF15 series

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.

1. Ingredients: The raw materials inspected and meeting the production requirements shall be matched according to the proportion of the production ingredients;
2. Feed: put the matching raw materials into the refiner for refining;
3. Crushing: crushing the refined raw materials into raw material particles of the size required for production;
4. Forolding: produce broken raw material particles to make materials of various thicknesses;
5. Collection: roll the formed materials at the same time of production;
6. Back glue: according to the needs of customers, attach double-sided adhesive to one side or double sides of the material, so as for customers to fit and use (and not back glue);
7. Cutting: According to the customer’s drawings or the size specified by the customer, the customer can use it directly after receiving the goods;
8. Inspection: Check whether the finished products meet the shipping specifications and requirements;
9. Packaging: package the finished products that meet the shipment requirements for delivery.

Penghui WLF15 series magnetic diaphragm features

1. Made of soft magnet ferrite and environmental friendly polymer material composite, with soft, easy to cut, can be processed into the required shapes and sizes according to customer requirements;
2. One or two-sided non-conductive double-sided adhesive, which is easy to fit and install when used;
3. A thin thickness that can be used in a narrow space;
4. The surface is smooth and smooth, no powder, not rotten edge;
5. It can improve the vortex heating problem generated when the wireless charger receiving terminal (RX) and the transmitter terminal (TX) are close to the metal, and improve the charging efficiency of the wireless charger;
6. Can improve the RFID electronic labels, antenna, reader, IC card, bus card and other radio frequency electronic products in the problem of reading and writing failure when encountering metal, play a role of anti-metal interference;
7. High surface resistance can be used in more complex circuits;
8. High-viscosity fit effect makes it more reliable when applied;
9. Through the ROHS, HF certification, with aging resistance characteristics.
10. A relatively low price can reduce customers the finished products while helping customers solve the problem of metal interference, which is very cost-effective.

Principle of rfid absorber material

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.
