Smart Ring PCBA Process

1. Board Type：4-layer rigid-flex with polyimide flex arm + FR4 rigid zone

2. Min. Trace / Spacing：0.075mm / 0.075mm (ultra-fine lines)

3. Surface Finish：ENIG (gold plating) for reliable soldering

4. Component Capability：Supports 01005 (0.4×0.2mm) and 0.4mm-pitch BGA

5. Inspection：100% AOI + X-ray for BGA void inspection

6. Protective Coating：Parylene nano coating + selective potting for sweat/moisture resistance

Smart Ring PCBA Application Scenarios

1. Consumer Health & Wellness

Smart rings are widely used in the consumer electronics field for real-time monitoring of blood oxygen saturation (SpO2), heart

rate (HR), heart rate variability (HRV), and single-lead electrocardiogram (ECG), providing users with daily health trend management.

2. Remote Patient Monitoring (RPM)
Smart rings are widely used in remote patient monitoring (RPM) scenarios, such as rehabilitation facilities, elderly care communities,

and post-operative follow-up centers, to continuously track patients' blood oxygen saturation and heart rate trends, assisting doctors

in conducting dynamic health assessments during outpatient periods.

Smart Ring PCBA Production Line

Our advanced SMT production lines are equipped with high-speed pick-and-place machines capable of mounting 01005

components. We implement strict process controls including vapor phase reflow soldering and automated optical inspection

to ensure every PCBA meets high-quality standards for wearable applications.
