Products Descrption

PCBA for EV Inverter is a highly integrated, precision-manufactured printed circuit board assembly specifically designed for the core control and power conversion functions of EV inverters. Unlike standard PCBA products, this solution is optimized for the harsh operating environments of EVs, including wide temperature fluctuations (-40°C to 125°C), high voltage (up to 800V), and continuous vibration.
The product integrates high-power semiconductor components (such as IGBTs and SiCs), high-precision sensors, and robust passive components, all mounted on a high-temperature-resistant substrate (FR-4 or ceramic). Each PCBA undergoes rigorous soldering inspection (AOI, X-ray) and functional testing to ensure consistent performance, minimizing the risk of inverter failure- a key concern for EV manufacturers and end-users.

Products Application

This PCBA solution is a critical component for EV inverters across multiple vehicle segments, with key application scenarios including:

Passenger EVs: Compatible with inverters for BEVs (Battery Electric Vehicles) and PHEVs (Plug-in Hybrid Electric Vehicles), supporting powertrain outputs from 50kW to 300kW (suitable for compact cars, sedans, and SUVs).

Commercial EVs: Designed for inverters in electric buses, delivery vans, and light trucks, where high durability and continuous operation (8–12 hours daily) are required.

Heavy-Duty EVs: Adaptable to inverters for electric trucks and construction vehicles, with reinforced mechanical structures to withstand extreme vibration and shock.

EV Aftermarket: Provides replacement PCBA modules for inverter maintenance, ensuring consistent performance with original equipment standards-addressing the growing demand for reliable EV aftermarket parts.

Products Features

PCBA for EV Inverter stands out with four core advantages, tailored to the evolving needs of the EV industry:
High Voltage & Thermal Stability: Supports DC input voltages up to 800V (compatible with next-gen EV batteries) and uses heat-dissipating substrates to maintain component temperatures within safe limits, even during high-load driving (e.g., uphill, fast acceleration).
Precision & Reliability: Adopts advanced SMT with 01005 component placement capability, ensuring tight circuit tolerances. 100% X-ray inspection for BGA components and IP67-level conformal coating protect against dust, moisture, and corrosion.
Energy Efficiency Optimization: Integrates low-loss power management chips and optimized circuit layouts, reducing energy conversion losses by up to 3% compared to standard PCBA solutions-directly contributing to longer EV driving range.
Customization Flexibility: Offers full OEM/ODM support to match diverse inverter designsfor passenger cars, commercial vehicles, and heavy-duty EVs. Shortens lead times for prototype developmentto accelerate client product launches.

FAQ

Q1: Does BQCTECH provide component sourcing for the PCBA, or do clients need to supply components?
A1: BQCTECH offers two options: 1) Full turnkey service: We source components through our global supplier network which will ensure traceability and cost efficiency); 2) Client-supplied components: We accept client-provided materials and provide assembly and testing services.

Q2: Can the PCBA be adapted for SiC inverter designs?
A2: Yes. Our PCBA is fully compatible with SiC power modules, which require higher temperature resistance and precision soldering. We have specialized SMT processes for SiC components, including laser soldering and thermal simulation testing.

Q3: What testing procedures does the PCBA undergo before delivery?
A3: Each PCBA goes through a 5-step testing process: 1) AOI for soldering defects; 2) X-ray inspection for BGA and hidden solder joints; 3) Functional testing ; 4) Environmental testing ; 5) Final visual inspection and traceability labeling.
