Assemble, Pack, and Quality Control


SMT Lines

Our factory is ISO 9001 compliant. This picture shows one of our SMT lines. SMT is used to manufacture PCB circuit boards, which are the heart of a smart watch. Our SMT production pass rate is higher than 99.5%, which is the advanced level in the industry.



The circuit board manufactured by the SMT production line will be embedded into the housing of the watch or bracelet, this small piece of watch, integrated with a pedometer, heart rate sensor, blood oxygen sensor, and other advanced components.

Water Resistance Test

The air leak machine is used to test the water resistance reliability, placing the product in a vacuum environment and extracting air from it, in order to test if it meets the waterproof level.


Charging Test

In this step, our quality control team will test each smartwatch for charging, so that we can confirm that the battery and charging of all products can work properly. We use high-quality lithium batteries that can reach up to 1000 times charge and discharge, enough to support more than 3 years.

Smart Watch Aging Test


Display Test

The display is one of the most important components in the entire smartwatch. We pursue the highest standard of quality control, using both machine and manual testing to ensure that each product’s display is stable, colorful, and free of bad dots.


Auto Packing

We use a fully automatic packaging system, which ensures close to 100% packaging accuracy, and this packaging system also adds blister film to the boxes to prevent damage due to moisture in the storage and transportation of the product.


Pack & Ship

Now the product is ready for ship, our QC team will make a final check on package and carton, to make sure it is all correct.
