High Volume PCB Testing Capabilities
At Kingda, we understand that energy storage systems and power electronics applications demand the highest level of reliability, safety, and performance. Whether it’s for BMS (Battery Management Systems), inverters, or power conversion modules, every PCB must withstand high current, high voltage, and thermal stress conditions.
Our experienced engineering and QA teams ensure that every PCB—regardless of volume—is rigorously tested throughout the entire manufacturing process. We implement strict quality control procedures to guarantee that all boards meet industry safety standards and long-term operational stability.
We specialize in high-volume production of power PCBs with thick copper, high-Tg materials, and precision layouts, ensuring consistent performance across all units. Every product undergoes extensive validation to minimize failure risks in mission-critical applications such as EV charging, renewable energy systems, and industrial power control.
As an ISO 9001:2015 certified company, we source all components from authorized and traceable suppliers, ensuring full traceability and eliminating risks associated with counterfeit or substandard parts—critical for energy applications.
Testing & Inspection Capabilities
To ensure optimal performance in demanding environments, we conduct the following tests:
- Design for Manufacturability (DFM)
Ensures your design supports high-current routing, thermal dissipation, and high-voltage isolation. - Design for Assembly (DFA) Checks
Identifies issues that may affect assembly efficiency or reliability in power modules. - AOI (Automated Optical Inspection) & AXI (X-ray Inspection)
Detects soldering defects, misalignment, and hidden joint issues in multi-layer and high-density boards. - Electrical Testing
Verifies continuity, insulation resistance, and performance under electrical load conditions. - Flying Probe Testing
Ensures electrical integrity without requiring test fixtures—ideal for complex designs. - Functional Testing
Confirms real-world operation, especially for BMS, inverters, and power control boards. - In-Circuit Testing (ICT)
Validates individual components and circuit behavior. - High Voltage / Insulation Testing
Critical for ensuring safety in energy storage and power electronics systems. - Solder Paste Inspection (SPI)
Ensures accurate solder volume for high-current components.
High Volume PCB Assembly Technologies
To meet the diverse requirements of power electronics applications, we utilize three advanced PCB assembly technologies:
Surface Mount Technology (SMT)
SMT enables compact, high-density designs essential for modern energy systems.
- Supports miniaturized power control modules
- Ensures high mechanical strength under vibration and thermal cycling
- Ideal for control circuits, signal processing, and communication modules
With decades of SMT experience, we ensure precision placement and high reliability, even in harsh environments such as renewable energy systems and EV infrastructure.
2.Through-Hole Technology (THT)
Through-hole assembly is critical for high-power components such as transformers, capacitors, and connectors.
- Supports high current carrying capacity
- Provides strong mechanical bonding
- Compatible with wave soldering and manual assembly
We offer complete THT services including:
- Double wave soldering
- RoHS-compliant processes
- Manual & automated insertion
- High-reliability inspection and testing
3.Mixed Assembly (SMT + THT)
Most energy storage and power electronics PCBs require a hybrid approach combining SMT and THT.
- SMT for control and signal circuits
- THT for power components and connectors
This optimized combination ensures:
- Electrical performance stability
- Mechanical durability
- Efficient thermal management

Energy Storage & Power Electronics PCB Assembly– FAQ
For high-power applications, materials such as high-Tg FR4, polyimide, or metal-core PCBs (MCPCB) are commonly used. These materials provide better thermal stability, insulation performance, and mechanical strength under high current and temperature conditions.
Power electronics PCBs usually require 2 oz to 10 oz copper thickness or higher, depending on current requirements. Thicker copper helps reduce resistance, heat generation, and voltage drop.
Thermal management is achieved through:
- Use of thermal vias and copper pours
- Integration of heat sinks or metal substrates
- Proper component spacing and layout optimization
- Use of high thermal conductivity materials
Main challenges include:
- Soldering large copper areas
- Managing heat dissipation during reflow
- Preventing warpage and delamination
- Ensuring strong solder joints for power components
A combination of:
- SMT (Surface Mount Technology) for control circuits
- Through-Hole Technology (THT) for high-power components
