Advantage of Cold lamination Technology
The cold laminating card sealing process (PCBA丨FPCBA) independently researched and developed by Union Smart breaks the traditional hot laminating, embeds the circuit board PCB in the card, and encapsulates the components such as thin batteries, Bluetooth modules, blockchains, switches, etc., which can be widely used Communication, financial payment, object positioning and other fields.
Meanwhile, it can be customized to add electronic ink display, fingerprint module, NFC, RFID, buzzer, etc. to achieve specific application functions.
