In 2018, our company successfully delivered a large batch of volume gate control boards for a Chinese client. This type of board is considered a standard board but requires both rapid delivery and high-level quality. The client requested the first batch to be delivered in just 17 days, which is significantly shorter than our usual 25–30 days lead time for similar projects. Recognizing this as an ideal fit for our capabilities, we decided to rise to the challenge and meet the customer’s demand.

Assembly Process Issue & Resolution

The silkscreen on this batch was incomplete, which could hinder component placement. Our engineering team resolved this by printing the assembly drawings directly from the *.pcb file and manually labeling areas without silkscreen. While this issue is rare, we now have a reliable process in place for such cases.

Product Function

This is a rolling gate control panel, primarily used for controlling the up-and-down motion of a rolling shutter. Users operate the shutter via wireless remote control. The board’s main controller acts as the central command system, issuing internal program commands to manage the motor and electric lock. Users can also adjust the opening speed and range through the controller.

Market Potential

This board is specifically designed for volume gates—a staple in almost every shop across China. Given the widespread use of rolling shutters, demand for this type of control board is immense, making it a high-demand product in the domestic market.

Final Notes

Below are detailed product images, showcasing our PCB manufacturing and assembly quality. For high-reliability PCBs, our company operates under the ISO9001 quality control system. If your project includes BGA components, we also offer X-ray inspection to guarantee soldering quality.
