MANUFACTURER DOSSIER
湖北中培电子科技有限公司 · Hubei
湖北中培电子科技有限公司 publishes a lighting-led PCB catalogue: aluminium-base boards, a copper-core example with PSR-4000 solder mask, glass-epoxy and composite boards, and flexible LED circuits. Its company page also describes single-sided, double-sided and multilayer fabrication, PCB design and PCBA work. The useful sourcing decision is which substrate and delivery scope fit your light engine or controller—not whether a photograph looks like your lamp.
The contact page places the operation beside Tangtu Avenue in Yangxin Economic Development Zone, Huangshi, Hubei. The company description also uses Xingye Avenue. Confirm the producing address and the legal entity on the quotation. The factory says it was established in 2013; Yangxin’s government report dates its arrival in Yangxin to 2015. These are separate events.
Heat moves from the component through solder, copper pattern, insulating layer and metal base into the mechanical interface. Request the dielectric grade and thickness, relevant test method, operating temperature and breakdown requirement together with the substrate. A copper-core title alone does not specify the thermal resistance of that path.
The copper-board title names PSR-4000. It does not identify a precise formulation, approved coating thickness or a material-batch certificate. Solder mask is also distinct from the insulating layer between circuitry and a metal base.
Yangxin’s original December 2024 company report describes collaboration with Hubei Polytechnic University on adhesive preparation, prepreg, rolling/hot pressing and heat-dissipation structures. It reports improvement using values written as 0.5 W and 1.5–2.0 W, without the full definition or test conditions needed to use them as thermal conductivity.
Those figures are not converted here into W/(m·K), nor attached to either catalogue board. Request a report for the selected material and construction. The manufacturer’s March 2026 news describes a high-thermal-conductivity series at small-batch trial stage, which likewise does not qualify every listed board.
Request copper-base thickness, dielectric grade and thermal resistance through the board-to-heatsink interface. Confirm which PSR-4000 formulation is approved and how insulation is tested.
Treat 100 W as the catalogue application label. Agree LED loading, ambient temperature, dielectric properties, heat-sink interface and temperature-rise acceptance for the complete luminaire.
The “100 W” label describes the intended catalogue application. PCBVerified does not turn it into a measured power-handling limit. Quote the LED arrangement, current, heat sink, interface material, enclosure and ambient conditions. Agree where temperatures are measured and which operating cycle is accepted before approving production.
Define mask reflectance and ageing criteria if relevant, LED footprint, current distribution and panel separation. A catalogue voltage/power label is not a board safety approval.
Release mains creepage, clearance, insulation, thermal and surge requirements with the luminaire circuit. The driverless wording does not demonstrate a safe or compliant complete lamp.
The catalogue calls the second example a “12 W / 220 V driverless” bulb board. That wording supplies neither an isolation rating nor a compliant assembled-lamp design. Define creepage, clearance, dielectric test, protective arrangement, surge behaviour and thermal limits for the actual circuit and housing. Decide which party designs the circuit and supplies the required product-compliance evidence.
The 12 V / 15 W bare-board title similarly does not prove an assembled output or a regulated drive current. If you want an assembled light engine, release the LED and driver BOM, component alternates, soldering profile, functional test and packaging as a separate scope from PCB fabrication.
Agree the FR-4 grade, copper, hole treatment and electrical-test revision. The single-layer title does not establish plated-through-hole construction.
Specify the exact CEM-3 grade, thickness, copper and lot traceability. Request the material certificate and approve any substitution against the design rather than accepting a brand name alone.
Several metal-board pages repeat a table containing 1–8 layers, 0.6–2.4 mm board thickness, 0.5–2 oz copper and 0.15 mm minimum line width, alongside a mixed list of FR-4, CEM-1, 22F, aluminium, high-Tg, Rogers and halogen-free materials. These are broad entries, not a stackup for the photographed copper or aluminium board.
The separate “single-layer metal board” page repeats that 1–8-layer row. Because the title and general table have different scope, no layer range is assigned to that sample here. Minimum spacing, finished-hole size and impedance tolerance are also not supplied by those entries. They remain unknown in numeric matching.
The CEM-3 product title names Kingboard but no grade. It does not establish a qualified purchase channel or current batch. Request the selected laminate’s part number and material record, define electrical/thermal requirements and prohibit unapproved substitution. The FR-4 title expressly says single layer; it supplies no copper thickness or Tg.
State the installed shape, static versus repeated flexing, bend radius, reinforcement and connector method. Do not infer a dynamic-flex lifetime from a strip photograph.
Approve the flexible stack, copper type, cover layer or ink, tail connection and stiffeners. Define bending conditions and inspection rather than importing the homepage values into this sample.
Specify the assembled shape, permitted bend radius, adhesive/backing, support, cut locations and connector strain relief. Agree how the strip is transported and installed without damaging the conductor or solder joints.
If the circuit will flex in service, define movement, cycle count, temperature and test configuration. The product pages do not publish a dynamic-flex qualification, copper grain type or film/adhesive stack. Ask for an approved construction and test evidence for that duty.
The homepage has separate PI, 0.1 mm and copper-text fragments near its material sections, but the individual flex pages do not connect them to these exact products. They are not silently transferred into the sample specifications. One page explicitly says single layer; the other does not state a layer count.
The company description reports a 33,000 m² site, 11,800 m² of buildings and 300,000 m² annual board capability. These are manufacturer statements about the operation, not reserved capacity for your order. Its April 2026 article describes phase-two construction and future introduction of LDI, storage controls and AOI.
The December 2024 Yangxin report describes a new phase-two factory under construction and a proposed 7,000 m²/day single-sided digital line. It does not establish that this line is commissioned now. The corporate phase-two investment wording also varies between its company description and later news; confirm the actual operating line rather than choosing the larger figure.
The 2026–2028 provincial “Silver Seed” reserve-company list, published by Hubei’s financial authority on 31 March 2026, includes the exact legal name. It is an enterprise-development listing, not proof of exchange listing, PCB quality, UL ownership or automotive approval.
The company and August 2026 quality article describe PCB/PCBA engineering, IQC, process inspection, final inspection and AOI. No current machine model, serial number or line-specific image inventory was established from these pages. Planned machinery is not described as already installed.
The homepage’s “View more” destinations include a cable-solutions page and another page advertising “since 2006” and “100+ assembly lines.” Their scope conflicts with the company narrative. Those claims are excluded from this profile. Confirm the assembly site, equipment, maximum panel and test coverage directly in the quotation.
Official company text claims UL, ISO9001 and NPS; the government’s 2024 report repeats historical qualification statements. Current issuer-verifiable certificate numbers, expiry and manufacturing scope were not supplied by the reviewed pages. No current certification badge is added. Request the required certificate-holder and product/site scope for your programme.
Individually researched9October2026:18original product pages/images,company/contact/datednews and two government originals. Eight corresponding examples selected for lighting, laminate and flex decisions. Broad repeated tables are not measured sample specifications; incomplete thermal units are not converted; planned equipment and certification claims are not current independently checked inventory or badges.
