Quality Control Process

External visual inspection

1. Packaging inspection (outer box label, product label, date code, quantity)

2. Appearance inspection (appearance integrity, degree of oxidation, whether there is a foot drop or reprocessing)

3. Supplier shipment document series (COC, inspection report, lead and lead-free specification)

4. Make sure the original factory

Instrument test

1. Carry out comprehensive functional and electrical characteristics tests at room temperature (25°C), including:

·Contact test

·Power consumption test

·Input leakage test

·Output level test

·Comprehensive dynamic parameter testing

·Comprehensive functional testing

·Analog signal parameter test

2. If the room temperature test is passed, the high/low temperature performance test can be carried out as needed

3. Take a certain number of samples for further electrical characterization to ensure long-term stability

Warehouse Logistics

1. Follow the "first in, first out" inventory management mechanism

2. Constant temperature management warehouse

(anti-static, dust-free, temperature and humidity control)

3. Abide by ISO9001 management requirements

Package

1. Vacuum packing

2. "Electrostatic discharge" protection against high temperature and high humidity

transportation

1. Designate cooperative logistics partners

2. Transparent and traceable transportation process

After-sales service

1. Confirm "Customer has received the goods"

2. Confirm "Passed Customer Quality Inspection"

3. "Customer return visit" after use

4. Commitment to "refund and exchange for quality problems within 30 days"

5. Joint third-party electronic component testing center technical support
