Q1: What is the lead time for OEM/ODM PCBA orders?
A: The lead time varies based on order quantity, customization complexity, and component availability. For standard customized PCBA (small to medium quantity, ≤1000 units), the lead time is 2-4 weeks from design finalization and component procurement. For mass production orders (>1000 units), lead time is 4-8 weeks. For ODM projects involving full design development, lead time is 8-12 weeks, including design, prototyping, testing, and mass production preparation. We work closely with global component suppliers to minimize procurement delays and ensure on-time delivery.

Q2: The PCBA be customized for specific battery chemistries and BESS power ratings?

A: Yes. Our engineering team has extensive experience in designing PCBA for various battery chemistries, including lithium-ion (NCM, LFP), lead-acid, and redox flow batteries. We can customize the BMS circuitry, power conversion modules, and control algorithms to match your battery's specifications . Additionally, our PCBA solutions support BESS power ratings from a few kW to several MW , with scalable designs to accommodate different project sizes.

Q3: What testing procedures do the PCBA products undergo?

A: Our PCBA undergoes a comprehensive testing process at every stage of production: 1) Incoming inspection: Testing of raw components to ensure quality and compliance. 2) In-process testing: ICT to detect soldering defects, component misplacement, and circuit continuity; AOI for visual defect detection. 3) Final testing: FCT to verify the PCBA's performance under real operating conditions; thermal testing, EMI testing, and reliability testing to ensure durability. All test data is documented and provided to customers for quality assurance.
