Penghe Technology cooperates with well-known electronic component manufacturers and top agents at home and abroad to purchase goods, ensuring that all components sold are original and genuine, with 100% quality assurance. All materials must undergo strict quality control processes before they can be released and handed over to customers.

External visual inspection:

1. Packaging inspection (outer box label, product label, date code, quantity)
2. Appearance inspection (integrity of appearance, degree of oxidation, presence of missing feet or reprocessing)
3. Supplier shipment document series (COC, inspection report, lead free specification sheet)
4. Ensure original factory packaging
