• Competitive analysis
• Bulk procurement strategies

What Is a UHF RFID ISO18000-6C Gen2 Wet Inlay?

A UHF RFID wet inlay is a type of RFID label that consists of:

• An RFID chip
• An antenna
• A substrate with adhesive backing

The term “wet inlay” refers to the fact that the inlay already includes adhesive and a liner, making it ready for direct application to products or packaging.

These inlays comply with the global RFID standard ISO 18000-6C Gen2, ensuring compatibility with most RFID systems worldwide.

Key Features

• Passive RFID (no battery required)
• Long read range (up to 20 meters under optimal conditions)
• Lightweight and flexible
• Cost-effective for mass deployment
• Easy to integrate into labels or stickers

Technical Specifications

How Is a UHF RFID Wet Inlay Manufactured?

The production of wet inlays involves precision microelectronics and high-speed automation.

1. Antenna Fabrication

The antenna is created using aluminum etching technology, where:

• Thin aluminum layers are etched into specific patterns
• The design is optimized for UHF frequency performance

This ensures:

• Strong signal transmission
• Efficient energy capture

2. Chip Attachment (Flip-Chip Bonding)

The RFID chip—such as Alien Higgs 3 chip—is attached to the antenna using flip-chip bonding.

This process:

• Ensures strong electrical connection
• Enables high-speed production
• Maintains consistent performance

3. Substrate Lamination

The antenna and chip are mounted onto a flexible substrate:

• PET (polyester) is commonly used
• Provides flexibility and durability

4. Adhesive Application (Wet Process)

A layer of adhesive is added to the back:

• Covered with a release liner
• Ready for peel-and-stick application

5. Testing and Encoding

Each inlay is tested for:

• Signal strength
• Read/write capability
• Data integrity

Working Principle of UHF RFID Wet Inlays

The wet inlay operates using passive UHF RFID technology.

Step-by-Step Process

1. An RFID reader emits radio waves
2. The inlay antenna captures the signal
3. The chip is powered by the signal
4. The chip sends stored data back to the reader
5. The system processes the data
