Once the design is finalized, the process enters the PCB (Printed Circuit Board) production stage. PCB manufacturing includes multiple steps, such as lamination, drilling, etching, surface treatment, and silkscreen printing to ensure accurate and reliable circuit connections.

After the PCB is completed, it moves into the SMT placement and DIP insertion stage. Components (such as resistors, capacitors, and IC chips) are precisely mounted onto the PCB using automated placement machines, and then soldered through reflow soldering or wave soldering to form the core functional modules of the electronic device.

3. Firmware Burning and Functional Testing

After the hardware is assembled, the software system also needs to be loaded. Technicians will burn the pre-developed firmware or operating system program into the device’s memory to make it operational.

Next, functional testing is carried out, including power tests, communication tests, user interface tests, etc., to verify whether each module works as expected. At this stage, automated testing platforms are also commonly used for fast detection.

4. Final Assembly

After the internal circuit has passed the tests, the electronic modules are integrated with structural parts (such as plastic or metal housings) for final assembly. This stage includes operations such as screw fastening, connector installation, display and button mounting, etc., ultimately forming a complete electronic device.

At the same time, an appearance inspection is carried out to confirm that there are no scratches on the casing, that the screws are firmly fixed, and that the structural assembly is correct.

5. Quality Control and Certification

Throughout the entire manufacturing process, every key point must undergo quality control. Before final delivery, the product must also go through full machine testing, aging tests, and safety certifications (such as CE, FCC, CCC), ensuring that its stability, safety, and compatibility meet industry and market standards.

For electronic devices used in medical, automotive, and other industries, higher certification standards may also apply (such as ISO , IATF , etc.).
