We deeply meet the core needs of smart audio devices for miniaturization, low power consumption and high fidelity, integrate high-quality electronic component resources, and through standardized full-process services such as SMT mounting, DIP insertion, and welding inspection, accurately assemble each electronic component on the circuit board. This ensures the excellent performance of products in audio transmission, signal processing, battery life control and other aspects, helping customers create more market-competitive smart audio products and empowering the innovative upgrading of the smart audio industry.

 

• Precise Adaptation to Smart Audio Scenarios: Deeply rooted in the smart audio field, we are familiar with the circuit design needs of various audio devices. Aiming at core functions such as Bluetooth transmission (supporting 5.0/5.2/5.3 versions), audio decoding and noise reduction processing, we optimize the assembly process, reduce signal interference, ensure the clarity and stability of audio transmission (SNR ≥100dB), and adapt to smart audio products of different sizes and functions. We also support 4-8 layer PCBs with 3mil/3mil minimum line width/line spacing, meeting the high-density layout requirements of small-sized smart audio devices.
• Strict Quality Control System: Complying with IPC-A-610 Class 2/3 standards, we are equipped with advanced AOI automatic optical inspection and SPI solder paste inspection equipment. From component screening, solder paste printing, component mounting to welding and cleaning, each link is strictly inspected to control the product defect rate to an extremely low level and ensure the long-term reliable operation of PCBA products, especially in maintaining stable performance of key parameters such as Bluetooth connection and SNR.
• Customized Flexible Services: We support full-process services from prototype proofing to mass production. According to customers' product design drawings and functional requirements, we can flexibly adjust the assembly process, including optional PCB layers (4-8 layers), adjustable minimum line width/line spacing (3mil/3mil or customized), and compatible Bluetooth version customization (5.0/5.2/5.3). We provide various process options such as single-sided SMT, double-sided SMT, and combination of SMT and through-hole components, meet the personalized customization needs of different customers, and shorten the product R&D and launch cycle.
• Cost-Effectiveness and Efficient Delivery: By vertically integrating the supply chain and optimizing the production process, we effectively control production costs while ensuring product quality and key parameter stability (such as SNR ≥100dB, Bluetooth 5.0/5.2/5.3 compatibility), providing customers with cost-effective solutions. With a professional production team and automated production lines, we can quickly respond to order needs, ensure on-time delivery of products, and help customers seize market opportunities.

1. Component Screening and Inspection: Strictly screen electronic components that meet industry standards, test the performance and quality of components through professional equipment, and prevent unqualified components from entering the production link.
2. Solder Paste Printing: Use high-precision solder paste printing equipment to evenly print solder paste on the pads of the circuit board, ensuring the uniformity and thickness of the solder paste, laying a solid foundation for subsequent component mounting and welding.
3. SMT Mounting: Adopt automated SMT mounting equipment to accurately mount chip components, integrated circuits and other components on the circuit board according to the design requirements, ensuring the accuracy and consistency of component placement.
4. DIP Insertion: For through-hole components that cannot be mounted by SMT, manual or automated DIP insertion is performed to ensure that the components are inserted in place and firmly fixed.
5. Welding and Cleaning: Use reflow soldering or wave soldering equipment to weld components and circuit boards, and clean the circuit board after welding to remove residual solder paste and impurities, ensuring the electrical performance of the product.
6. Final Inspection and Testing: Conduct comprehensive electrical performance testing, visual inspection and functional testing on the assembled PCBA products to ensure that the products meet the design standards and customer requirements before leaving the factory.

 

BQC (Batch Quality Control) is our core quality assurance link for PCBA assembly. We implement strict batch inspection and control throughout the production process, from incoming material inspection of components to finished product testing. BQC ensures that each batch of PCBA products meets the consistent quality standards, effectively reduces batch defects, and provides reliable quality guarantee for customers' smart audio products.
