The RFID card inlay is two or three PVC/PET layers laminated with embedded chip and antenna, also called chip material or pre lam (pre-laminating), it is a semi-finished product and core component of RFID card. Produced in the early stage of card production, RFID card inlay allows card factories to economically produce printed and personalized card easily and shorten production time.
1, ultrasonic embedding copper antenna, reasonable COB design, guarantee high consistency, reliable performance.
2, reliable spot welding guarantee very solid welding point, the pull force exceeds 80g, minimize the card mal-function rate
3, brand new high quality PVC/PET material ensures the sturdiness, and easy to process,
4, chip shelter processing and high temperature steel sheet laminating technique guarantee the flatness of the whole inlay, no bumps on the inlay.
5, Trimmed reference edges and optional printed cross marks to make the further process easier.
6, semi-finished core material of RFID cards, it helps lower down the production cost of printed and personalized RFID cards.
7, it has complete most of the early stage work of a RFID cards, it shorten the production cycle dramatically

Standard contactless card inlay is mainly used to produce standard contactless cards, including RFID PVC Card, RFID PET Card, low frequency card, high frequency card, UHF card etc.
Card pre lam producing:
Automatic wire implanting machine implants wire for 5 chips simultaneously and evenly with stable gap. Proudtek provides card inlay with very good frequency consistence.
Automatic welding machine soldering the antenna to COB connect pads accurately and efficiently, it is more stable work and faulty rate can be controlled very well.China Prelam manufacturers
