Quality Control System — Full-Chain Management from Raw Materials to Factory Exit

In the semiconductor industry, even the tiniest defect can lead to the scrapping of an entire batch of wafers. Building a full-chain quality control system from raw materials to final delivery, with a "zero-defect" philosophy embedded in every manufacturing step, is the foundation of survival for semiconductor component enterprises.

 

Raw Materials: Strict Selection

From automatic cutting machines slicing raw materials to drying furnaces relieving stress, every step follows standardized operating procedures. CNC lathes and machining centers perform precision machining and hole drilling, while tool setting instruments ensure cutter accuracy and dynamic balancers guarantee machining stability.

 

Surface Treatment: Multi-Layer Verification

After each surface treatment process — chemical cleaning, sandblasting, anodizing, brush plating with nickel — corresponding inspection methods are applied. Key tank solution parameters including pH value, concentration, metal ions, conductivity, and particulate matter are monitored in real time to ensure full process controllability. The measured breakdown voltage of mixed-acid hard anodizing reaches 4.2KV–4.65KV, significantly outperforming industry standards.

 

Welding: Zero Tolerance for Defects

All four major welding processes — electron beam welding, friction stir welding, vacuum diffusion bonding, and vacuum brazing — are equipped with professional welding defect analysis systems for precise detection and evaluation of welding anomalies.

 

Factory Exit: Eight-Dimensional Inspection

Dark light inspection, gas flow detection, organic contamination analysis, micro-particle detection, surface metal trace analysis, material composition analysis, liquid particle count detection, and chemical residue analysis — eight inspection dimensions ensure every product leaving the factory meets all standards.

 

AMTD, with its full-chain quality control system, proves to the industry: Chinese manufacturing can meet and even exceed international standards. Quality control is not a cost — it is the core competitiveness of semiconductor component enterprises.
