SummaryCoretek (Shenzhen) Electronics Co., Ltd is a China-based limited company in Shenzhen, Guangdong, identified as a trading company, manufacturer/factory, and group corporation, although no associated company is indicated. It offers a broad range of electronic components and modules, has in-stock capability, and reports export sales of 90%. Its stated management-system certifications include QHSE, ISO 9000, ANSI/ESD, ISO 9001, ISO 14001, ISO 14000, QSR, and EICC. Production-related evidence includes 6–10 quality-control staff, annual output within the stated non-financial range, and lead times within 15 workdays in both peak and off seasons. Quality assurance and raw-material traceability are reported, but there are no written corrective-action or complaint-handling procedures. R&D engineer experience is under five years and no SDK is available. Overseas support is limited: no overseas warehouse, showroom, agents, branches, or offline trade-show participation are reported.

CertificationsThe supplier reports certifications or system holdings including QHSE, ISO 9000, ANSI/ESD, ISO 9001, ISO 14001, ISO 14000, QSR, and EICC. These stated certifications provide explicit evidence of formal quality, environmental, ESD, and related management-system coverage.

After-Sales capabilityThe supplier has in-stock service capability and reports lead times within 15 workdays in both peak and off seasons, but it has no written complaint-handling or corrective/preventive-action procedures or records. It also reports no overseas warehouse, showroom, agents, branches, or overseas-service countries, indicating documented after-sales processes and international service coverage are limited.

R&D capabilityThe supplier offers products including AI/GPU and high-end chips, but its R&D engineer experience is reported as under five years and no SDK is available. The explicit absence of an SDK is a stated limitation for development support.

Production capacityEvidence supports manufacturing capability through the manufacturer/factory designation, 6–10 quality-control staff, quality assurance, raw-material traceability, in-stock capability, and reported lead times within 15 workdays in both seasons. However, the supplier reports zero quality-control capability for own-brand quantities, so capability is stronger for general supply than for own-brand quality-control scope.
