Last week, Ring PCB received a repeat purchase order from one of our long-standing partners in France—an established smart home solutions provider who has now worked with us for three consecutive years. The latest order consists of 50,000 pieces of printed circuit boards and full PCBA assemblies designed for integration into their next-generation intelligent door lock systems. This project once again reflects the trust they place in our manufacturing expertise, rapid response capability, and commitment to consistent quality.

Rapid Prototyping Delivered Within 48 Hours

Upon receiving the customer’s engineering files and updated specifications, our technical and production teams immediately coordinated to launch the prototype phase. Thanks to our streamlined workflow, complete in-house SMT lines, and mature engineering review process, we delivered fully functional prototypes within 48 hours.

During this period, we maintained real-time communication with the customer to verify every detail—from board structure and surface treatment, to solder mask color, assembly footprint requirements, firmware loading interface, and final testing procedures. Our rapid prototyping ensured that the customer could evaluate the design quickly and confirm all production details without delay, keeping the project fully on schedule.

Confirmed Requirements and Smooth Transition Into Mass Production

Once the prototype passed review on the customer’s side, we immediately transitioned into mass production. Leveraging our automated equipment and well-trained production teams, we strictly followed the customer’s BOM, assembly sequence, and functional testing standards to ensure full consistency across all 50,000 units.

Currently, the order is in active mass production, and all processes—from PCB fabrication to SMT placement to AOI inspection—are progressing smoothly. Based on our production planning, the order will be fully assembled, packaged, and ready for shipment by this Friday, enabling the customer to meet their market launch timeline without compromise.

High-Precision Manufacturing and Professional Craftsmanship

This long-term partnership has benefited greatly from our proven expertise in high-precision PCB and PCBA manufacturing. For this smart lock application, the boards require:

• Strict impedance control

• High-precision SMT processing suitable for micro-components

• Stable performance under varying environmental conditions

• Perfect compatibility with the customer's housing design and functional modules

Our engineering capabilities allow us to execute every stage—from lamination and drilling to solder paste printing and reflow profiling—with maximum accuracy. Whether producing small batches or large-scale orders, our process control ensures consistent reliability.

100% Quality Inspection Ensuring End-Product Reliability

Quality assurance is a cornerstone of Ring PCB’s service. For this project, we implemented full-process, 100% inspection, including:

• Electrical testing (E-test)

• Automated optical inspection (AOI)

• X-ray inspection for BGAs and hidden solder joints

• In-circuit testing (ICT) and functional testing (FCT) according to customer requirements

Every unit is thoroughly checked before packaging. This level of testing is essential for products used in smart security systems, where stability and long-term performance cannot be compromised.

Efficient Packaging and Logistics to Support the Customer’s Global Supply Chain

To ensure the boards arrive in perfect condition, our logistics team handles anti-static packaging, multi-layer protective materials, and shock-resistant export cartons. With our optimized workflow, we minimize lead time from production to shipment. For this project, we are on track to dispatch all goods before Friday, supporting the customer’s global distribution schedule.

A Partnership Built on Reliability and Professional Excellence

This French client has chosen to work with Ring PCB for the third consecutive year because of our:

• Fast response and flexible cooperation model

• Stable and reliable manufacturing quality

• Professional engineering support

• On-time deliveries for both prototypes and mass production

• Ability to scale production rapidly when the customer’s market demands increase

The success of this 50,000-piece smart lock PCB/PCBA order reinforces our commitment to helping international clients innovate and succeed in competitive smart home markets.
