Smart Lock PCB Assembly Solutions
We provide professional smart lock PCB assembly and PCBA manufacturing services for global OEM and ODM customers in the security and smart home industries. Our solutions are designed to meet the high reliability, security, and durability requirements of modern smart lock products used in residential, commercial, and hospitality applications.
The smart lock PCBA is the core electronic module that controls authentication, communication, motor drive, and power management. Our experience covers control boards for smart door locks, including MCU-based logic boards, communication modules, power supply boards, and motor control PCBs. These PCBA solutions support multiple unlocking methods such as PIN code, RFID, Bluetooth, fingerprint, and mobile app control.
Our PCB assembly capability supports complex and compact smart lock designs that require high integration and stable performance. We provide advanced SMT PCB assembly for fine-pitch components, high-density layouts, and multi-layer PCBs. Components such as MCUs, secure chips, Bluetooth and Wi-Fi modules, sensors, and power management ICs are assembled using automated SMT lines to ensure placement accuracy and soldering reliability.
Quality and consistency are critical for smart lock PCB assembly, especially for products exposed to frequent mechanical operation and long-term residential use. Every PCBA undergoes strict quality control procedures, including SPI, AOI, and functional testing. Functional tests can be customized to verify communication stability, motor drive performance, power consumption, and system response. Where required, X-ray inspection is applied to ensure solder joint integrity for BGA and QFN components.
To support customer product integration and mass production, we offer value-added services such as firmware programming, parameter configuration, serial number assignment, and customized labeling. All PCB assembly processes are fully traceable, from incoming materials to final shipment, helping customers manage quality control and after-sales service efficiently.
Our engineering team works closely with customers from the early development stage. By applying DFM and DFA principles, we help optimize PCB layout, reduce assembly risks, and improve production efficiency. Flexible MOQ options support prototype builds and pilot runs, while scalable SMT PCB assembly capacity ensures smooth transition to mass production.
All smart lock PCB assembly and PCBA services are carried out under an ISO-certified quality management system. We support compliance with CE, RoHS, and other international standards, helping customers meet regulatory and market access requirements in Europe and North America.

Q: What Base Materials Does Tengxinjie Offer for PCB Manufacturing?
A: Tengxinjie offers a wide selection of PCB Base Materials, including standard FR4, HDI PCB, Flexible PCB, Rogers PCB, Teflon, copper-core, and aluminum substrates. With these options, you can easily select the most suitable material to ensure the best performance for your project.
Q: Does Tengxunjie accept small-batch or prototype orders?
A: Yes. We support small-batch production and prototype orders, typically with minimum order quantities ranging from 10 to 200 pieces.
However, small-batch production may result in higher unit costs, and certain electronic components have minimum order quantity (MOQ) requirements.
Partnering with a flexible PCBA supplier enables startups and R&D teams to advance product development without significant upfront investment.
Q: What is the typical PCBA lead time? What affects delivery time?
A: PCBA lead time depends on order size and project complexity. Typical estimates are:
Prototype builds: 5–10 working days
Small-batch production: 10–15 working days
Mass production: 15–30+ working days
Key factors that impact lead time include:
Component availability and specified brands
Turnkey service scope
PCB layer count and complexity
Testing and inspection requirements
An experienced PCBA manufacturer can help manage these factors to keep your project on schedule.
Q: How are PCBA boards packaged and shipped?
A: PCBA boards are packed according to their sensitivity and shipping method. Standard packaging includes:
ESD-safe anti-static bags
Bubble wrap, foam, or anti-static trays
Moisture-proof, labeled outer cartons with tracking information
For medical, automotive, or high-reliability electronics, cleanroom packaging or special handling is available.
Most PCBA suppliers support air freight, sea freight, and express courier based on order size and urgency.
Q: What are the advantages of turnkey PCBA and one-stop manufacturing?
A: Turnkey PCBA services mean the manufacturer handles everything — Electronic component sourcing, PCB fabrication, PCB assembly, testing, and logistics.
A reliable one-stop PCBA supplier helps customers:
- Simplify supply chain management
- Reduce sourcing and communication errors
- Shorten production lead time
- Speed up time-to-market
This is especially valuable for OEMs, startups, and engineering teams that need fast and stable production.
Q: How do we ensure the quality of electronic components used in assembly?
A: We maintain a rigorous supplier qualification process and a global procurement network, sourcing parts exclusively from authorized and trusted distributors. All incoming components undergo stringent inspection to verify authenticity and quality before being deployed.
