- Cost Reduction: Streamlined assembly and reduced BOM complexity led to an 8.2% decrease in total unit cost.
- Performance Upgrade: Improved thermal dissipation and trace shielding improved stability in fluctuating environments by 47%.
- Lead Time Optimization: Total PCBA delivery cycle was reduced from 4 weeks to 2.3 weeks, accelerating the client’s product launch.
5. KKPCB Advantages Demonstrated in This Project
KKPCB leveraged its end-to-end capabilities from multilayer PCB fabrication to high-precision PCBA assembly to deliver a stable and miniaturized sensor solution. Through rigorous DFM checks, X-ray inspection, AOI, and customized functional testing, we ensured zero-defect delivery. Our proactive engineering support and flexible production scheduling helped the client overcome prototyping challenges and meet aggressive go-to-market timelines.
6. KKPCB’s Custom Manufacturing-Focused Solution
Understanding the client’s need for ultra-compact and high-accuracy PCBA, KKPCB proposed a 4-layer PCB stack-up with tight impedance control and moisture-resistant board finish. We applied selective conformal coating to protect key sensing components from condensation without interfering with sensor accuracy. Components were placed with a ±20μm accuracy using our SMT line, ensuring optimal performance in extreme conditions.
We also offered value-added engineering support, such as component substitution proposals during material shortages, and delivered complete traceability documentation in line with European regulatory compliance.
7. Real-World Impact of the Solution
Thanks to KKPCB’s tailored manufacturing approach, the client reported:
- Zero field failures during the first six months of deployment
- A 14% improvement in environmental data accuracy under high-humidity conditions
- A 10% decrease in system-level energy consumption due to faster, more stable sensor feedback
- A 2-month earlier market entry than originally scheduled
