Inlay with multiple label units

By attaching an aluminum foil shielding layer to tag units with radio frequency performance 3dBm below the standard, the principle of electromagnetic wave reflection or absorption is used to make them appear as having no signal in existing detection equipment. This solves the problem that defective products with radio frequency performance 3dBm below the standard cannot be screened, and achieves the effect of preventing abnormal products from flowing into end customers.

AI Technical Summary

Technical Problem

In the existing technology, defective products with radio frequency performance below the standard by 3dBm cannot be effectively screened by the testing equipment in the subsequent process, resulting in them flowing to the end customer and causing problems such as abnormal use and time-consuming and labor-intensive manual confirmation.

Method used

An aluminum foil shielding layer is pasted into the tag unit whose radio frequency performance is 3dBm lower than the standard. The aluminum foil shielding layer reflects or absorbs electromagnetic waves, ensuring that these tag units show no radio frequency signal in existing detection equipment, and are thus rejected.

Benefits of technology

This effectively prevents defective products with RF performance below the standard by 3dBm from reaching end customers, avoiding usage abnormalities and manual verification, and saving labor costs.
