Strict Quality Control, Craftsmanship Protects Every Device

1. Raw Materials Storage

   
   

   All core components come from strictly certified suppliers and are stored in a standardized manner in a constant temperature and humidity environment, ensuring quality from the source.
   
   
2. Incoming Quality Control (IQC)

   
   

   A professional inspection team conducts multi-dimensional testing on each batch of raw materials. Only materials that pass all tests including electrical performance, appearance, and reliability can enter the production process.
   
   
3. Welding

   
   

   High-precision automated welding equipment is used, combined with manual calibration by professional technicians, to ensure that every solder joint is firm and free of cold solder joints, guaranteeing the long-term stability of the circuit.
   
   
4. Function Testing

   
   

   In an environment simulating real working conditions, comprehensive tests are conducted on the core functions, response speed, and anti-interference ability of the equipment to verify that its performance meets standards.
   
   
5. Assembling

   
   

   Following standardized operating procedures, precision assembly is completed in a dust-free workshop to minimize human errors and ensure the consistency of equipment structure.
   
   
6. Semi-finished Testing

   
   

   Multiple rounds of aging tests and pressure tests are conducted on the assembled semi-finished products to detect potential problems in advance and prevent defective products from entering the next stage.
   
   
7. Final Inspection of Finished Products

   
   

   Before leaving the factory, each device undergoes a final round of full-function verification and appearance inspection. Only products that pass all tests with 100% accuracy can be labeled with Coolmay's certification of conformity.
