Quality assurance
The company has established a systematic supplier tiered management system and uses a full-process ERP system for management. We implement tiered inspection mechanisms tailored to each supplier level to ensure product consistency, traceability, and delivery reliability.
Supplier Categories
Inspection Process
Shipment Inspection (OQC)
All outbound materials must be re-checked before shipment to confirm that the order and delivery note model, brand, quantity, packaging, year, moisture level (MSL) check, packaging, product code, etc. are all correct, and the label is also checked again to ensure customer receipt with "zero deviation and zero complaints."
Advanced inspection measures
For non-traceable materials, advanced inspections are carried out as required, including X-RAY, open cap analysis (DE-CAP), weldability testing, and commissioning third-party laboratories (designated Baima Laboratory) for specialized testing;
Incoming Materials Inspection (IQC)
Applicable to all material categories, with a focus on checking incoming material label information (brand, model, production date/batch number, quantity), and the integrity of the outer packaging, among other routine items;
Standardized Warehouse Management
Real-time temperature and humidity monitoring
The warehouse is equipped with a real-time environmental monitoring system to ensure that the storage environment always meets the safe storage conditions for electronic components.
Ground resistance testing
All ESD grounding protection devices (such as wrist straps, mats, and shelves) undergo regular grounding resistance tests according to industry standards and are recorded to ensure they consistently maintain compliant grounding performance.
Electrostatic protection measures
All operators are equipped with anti-static wrist straps and ensure effective grounding during operation.
The workbench is covered with anti-static rubber pads to effectively block static buildup.
All storage racks are connected to ESD grounding wires, ensuring comprehensive static discharge throughout the system.
MSL (Humidity Level) management
To ensure the safe storage and handling of MSL Level ≥3 moisture-sensitive devices, the warehouse is equipped with the following professional measures:
Vacuum Packaging Equipment: Used for secondary vacuum sealing of unsealed and inspected moisture-sensitive devices, ensuring moisture-proof safety during subsequent storage.
Constant temperature and humidity sealed cabinet: Used to store tested but not yet shipped moisture-sensitive components. The cabinet body controls temperature and humidity within specified ranges to effectively manage moisture resistance.
