Electronic tag foil is usually used for RFID tag antenna, RFID tag antenna is RFID transponder transponder antenna, is a communication sensor antenna. Generally integrated with the chip to complete the RFID tag reader. RFID tag antenna due to material and manufacturing process is different, divided into metal etching antenna, printed antenna, copper antenna, and several.
Etching method: circuit board (PET aluminum foil) compound → curing → circuit printing and UV curing → etching → to ink cleaning → circuit conduction processing → coil cutting → circuit testing → inspection packaging;
Printing method: PET film → circuit printing and UV curing → coil slitting → circuit characteristic detection → inspection packaging.
RFID antenna production technology mainly etching method, coil winding method and printing antenna three. Low frequency LF RFID tag antenna is basically made by winding method, high frequency HF RFID tag antenna can be achieved using the above three ways, but the etching antenna, the material is generally aluminum or copper.
And we generally see the electronic label antenna material for the aluminum alloy, which is the electronic label aluminum foil, the advantages of electronic label aluminum foil have the following:
1, strong mechanical properties, anti-blasting performance, anti-puncture and tear resistance;
2, excellent moisture resistance, shading and high barrier capacity;
3, the surface clean, uniform color, no pattern, no oil, flat without pinholes;
4, bacteria, mold and many other tests, heavy metals do not exceed 0.55 million, strictly enforce the industry standards to ensure safety and health.
huawei Aluminum can produce electronic label aluminum foil thickness range of 0.018mm-0.2mm, according to customer requirements width control in the 100-1650mm. Long-term cooperation in a number of domestic and foreign enterprises to verify the quality of huawei Aluminum products in full compliance with the needs of customers, orders rose and then rise.
