Naipu Circuit Technology
PCBs and SMT assembly from a Dongguan micro-enterprise with a production-and-R&D scope, import/export clause and National High-Tech Enterprise status.
PCBs and SMT, from the scope.
Aluminum-Base PCBs (铝基板)
Metal-core PCBs for LED lighting, power supplies and automotive electronics where heat dissipation is critical. Specify the dielectric layer thickness, thermal conductivity target (W/m·K), copper weight and surface finish.
Copper-Base PCBs (铜基板)
Copper-substrate boards for high-power and high-frequency applications. Key specifications: copper thickness, dielectric material, Tg value, impedance control requirement and any UL or IPC class.
Thermal-Separation PCBs (热电分离线路板)
Boards that separate the thermal path from the electrical path, used in high-power LED and power-electronics packaging. Ask for the thermal-resistance specification and cross-section structure.
Single / Double / Multi-Layer PCBs
Standard rigid PCBs from single-sided through to multi-layer stack-ups. Specify layer count, material (FR-4, CEM-3, Rogers), copper weight, minimum trace and space, via structure and IPC class.
SMT Assembly (贴片加工)
Surface-mount assembly services — solder-paste printing, pick-and-place and reflow. Ask for component sizes handled (down to 01005 or 0201), placement accuracy and line capacity.
LED Components & Electronics
LED chips (灯珠) and electronic products are in the registered scope. Confirm which LED packages are stocked or produced, and ask for binning and luminous-flux specifications.
What the registry confirms, and what stays open.
A Micro-Enterprise with a Production Scope
The company was registered on 2020-03-12 with RMB 500,000 of fully paid capital. It has 4 insured staff and is classified as a micro enterprise (小微企业). Its registered scope covers R&D, production and sales of specific PCB types plus SMT assembly — a manufacturing clause on a very small company. Ask for a factory tour or video to understand the production capacity behind the scope.
PCB Types Named in Scope
The scope individually lists aluminum-base, copper-base, thermal-separation, single-sided, double-sided and multi-layer circuit boards. This level of specificity is unusual for a generic electronics company and points to PCB fabrication as the declared core activity.
Import/Export in Scope
The scope includes 货物或技术进出口 (import/export of goods or technology), so the company is registered to trade directly with overseas buyers. This is a meaningful difference from the previous two factories.
National High-Tech Enterprise
The enterprise record carries the 高新技术企业 (National High-Tech Enterprise) designation, a government-assessed title that requires meeting criteria for R&D spending, IP ownership and revenue from high-tech products. This designation is noted on the enterprise record.
Registered as Wholesale, Scope Says Production
The registered industry code is 批发业 (wholesale), while the scope explicitly lists production (生产). The industry code may reflect the initial registration or primary revenue classification. The scope is the controlling document for what the company is licensed to do.
Room-Number Address, 4 Insured Staff
The registered address is a room (105室) in a building in Shuitian Town, Dongguan. With 4 insured staff, the on-site production capacity is an open question. The background note says this is a wholly-owned subsidiary of Shenzhen Naipu — production may run at the parent’s facility. Confirm where boards are actually fabricated.
What was checked — and what the check found.
The stamp rests on a registry check: the credit code passes the national check-digit rule, the company is active with a PCB production, R&D and import/export scope and carries the National High-Tech Enterprise designation. What stays as notes: it is a 2020 micro-enterprise with RMB 500,000 of capital, 4 insured staff and a room-number address — scale and actual production location are the open checks. Background notes identify it as a wholly-owned subsidiary of Shenzhen Naipu; if production runs at the parent, confirm that in writing.
A Dongguan PCB micro-enterprise, read off the record.
Dongguan Naipu Circuit Technology Co., Ltd. (东莞市耐普电路科技有限公司) was registered in March 2020 in Shuitian Town, Dongguan. Its scope covers R&D, production and sales of aluminum-base, copper-base, thermal-separation, single-sided, double-sided and multi-layer PCBs, LED chips, electronic products and SMT assembly, plus import/export of goods and technology.
The company is classified as a micro enterprise with 4 insured staff and RMB 500,000 of fully paid capital. It holds the National High-Tech Enterprise designation on the enterprise record. Background notes identify it as a wholly-owned subsidiary of Shenzhen Naipu, with a website at naipupcb.com.
The registered industry code is wholesale (批发业), while the scope explicitly lists production. The address is a room number, not a factory floor. Buyers should confirm where PCBs are actually fabricated and what production capacity is available. Contact routes through ChinaMakersHub; direct details are exchanged after first inquiry.
From a 2020 registration, on the record.
Company registered in Dongguan
Dongguan Naipu Circuit Technology Co., Ltd. is registered in March 2020 with a PCB production, R&D and import/export scope. Confirmed on the enterprise record.

The company earns the National High-Tech Enterprise designation, noted on the enterprise record.
Listed on ChinaMakersHub
Registry read 2026-09-30: active, PCB production and R&D scope, import/export clause, National High-Tech Enterprise, 4 insured, micro enterprise. Open: production location and capacity.
What would move it forward
A factory tour or video, production-capacity data, IPC or UL certifications, and confirmation of the manufacturing site.
Who these boards are for.
LED Lighting Manufacturers
Aluminum-base and copper-base PCBs for LED modules, drivers and thermal management. Specify thermal conductivity, dielectric thickness and UL requirement.
Power Electronics Companies
Thermal-separation and metal-core PCBs for power converters, inverters and motor drives. Key: current-carrying capacity, thermal resistance and IPC class.
Consumer Electronics Brands
Multi-layer rigid PCBs and SMT assembly for consumer devices. Ask for impedance-control capability, minimum feature size and component-size range.
Automotive Electronics Suppliers
PCBs meeting automotive-grade requirements (IATF 16949, AEC-Q). Confirm whether automotive qualifications are held and at which facility.
Small-Batch & Prototype Buyers
A micro-enterprise scope may suit small-batch and prototype orders. Confirm minimum order quantities and lead times for quick-turn PCBs.

Frequently Asked Questions
What does Naipu Circuit Technology make?
PCBs — aluminum-base, copper-base, thermal-separation, single-sided, double-sided and multi-layer circuit boards — plus SMT assembly and LED components, in Dongguan. The scope also covers import/export.
Is it a manufacturer?
Its registered scope covers R&D, production and sales of named PCB types plus SMT assembly, so it has a manufacturing clause. However, it has only 4 insured staff, a room-number address and a wholesale industry code. Background notes identify it as a subsidiary of Shenzhen Naipu; production may run at the parent facility. Ask where boards are fabricated.
Can it export directly?
Yes. Import/export of goods and technology is in the registered scope.
What certifications does it hold?
The enterprise record carries the National High-Tech Enterprise designation. No product-specific certifications (IPC, UL, IATF) have been sighted on this listing. Ask directly.
