Product Definition: The intelligent ring is a simple, lightweight, and intelligent wearable device. It originates from wristbands, smart watches, and focuses on monitoring health and exercise-related data as well as uploading sensor data to the cloud server. Bluetooth IoT combined with NFC effectively expands the IoT control functions, access control unlocking, and electronic payment functions of the intelligent ring. The intelligent ring is a subtractive product in the era of adding functions to mobile phones, with its specific personalized significance.
Most of the product forms of the intelligent ring are dominated by soft boards and soft-hard combined boards processes. A few product forms have rigid circuit boards as their base. The soft-hard combined circuit board process can effectively incorporate more functional circuits into the space of the ring. Based on the specific space and function requirements of the intelligent ring, we can provide ODM services for circuit board components based on the soft-hard combined process for customers.
Product features and highlights: Due to the limited space of the smart ring, the soft and hard composite board must be extremely thin. The connection area between the local hard board sections and the local soft board sections is very narrow, which poses a considerable manufacturing challenge.
Product Applications: Bluetooth hard networking smart ring, health monitoring smart ring, exercise monitoring smart ring, NFC identification smart ring, NFC digital RMB payment smart ring, NFC wireless charging smart ring, etc.
