About Ke You Pcb Co., Ltd - PCB Supplier in China

Ke You Pcb Co., Ltd is based in China and currently lists seven distinct PCB‑related items in its catalogue. The product portfolio falls under the printed circuit board (PCB) category, which is classified internationally under HS chapter 85, commonly HS codes 8542.31 to 8542.33 for single‑sided, double‑sided and multilayer boards. Each listing references a specific type of board or assembly, ranging from charger boards with ENIG finish to Bluetooth earphone modules and medical‑meter PCBA. The catalogue also includes flexible formats such as rigid‑flex boards and standard double‑sided prototypes, as well as complete PCBA and OEM USB charger assemblies. The supplier’s trust tier is identified as “harbor,” indicating a moderate level of verification within the platform.

The ENIG Charger Printed PCBs and Bluetooth Earphone ENIG PCBs use electroless nickel immersion gold surface finish, a common choice for high‑frequency and corrosion‑resistant applications. The Rigid‑flex and Double‑Side Rigid PCBs are typically fabricated on FR‑4 substrate with copper thickness of 1 oz per square foot, trace widths down to 6 mil, and comply with IPC‑2221 design standards. The Uric Acid Meter PCBA and the generic PCBA Assembly are supplied as fully populated boards, often requiring compliance with medical device standards such as IEC 60601. The USB Charger PCB Assembly OEM is marketed for power conversion and typically incorporates a 5 V output, meeting IEC 60950 safety requirements. All items are produced in China, where PCB manufacturers frequently hold ISO 9001 quality management certification, although specific certificates are not listed for this supplier. Buyers can expect the listed products to be shipped in anti‑static bags within corrugated cartons, suitable for container loading.

Product Range and Specialties of Ke You Pcb Co., Ltd

The catalogue covers seven PCB products: ENIG‑finished charger board, Bluetooth earphone ENIG board, a Uric Acid Meter PCBA, a rigid‑flex printed board, a double‑side rigid prototype, a generic PCBA assembly, and a USB charger PCB assembly offered as OEM. In the broader industry, ENIG finish is rated for surface planarity and corrosion resistance, while rigid‑flex boards combine flexible polyimide layers with rigid FR‑4 for space‑constrained devices. Double‑side boards are commonly produced with 1 oz copper and meet IPC‑A‑600 visual standards, and multilayer or rigid‑flex designs often require controlled impedance testing. PCBA assemblies for medical instruments usually need IEC 60601 compliance and RoHS‑free solder paste. USB charger assemblies are subject to IEC 60950 or IEC 62368 safety testing, and typical packaging includes anti‑static bags, moisture‑absorbing desiccants, and sturdy cartons for 20‑ft or 40‑ft container shipments.

Trade and Export Information - Ke You Pcb Co., Ltd

China remains one of the world’s largest exporters of printed circuit boards, with major import markets in North America, Western Europe, and Southeast Asia. Buyers of Chinese PCBs typically reference HS codes 8542.31 (single‑sided), 8542.32 (double‑sided) and 8542.33 (multilayer) for customs declarations, and they often request certificates such as ISO 9001, UL, CE and RoHS conformity to satisfy regional regulatory requirements.

Logistically, PCB shipments are usually packed in anti‑static bags inside double‑wall corrugated cartons, and loaded into 20‑ft or 40‑ft containers under FOB Shanghai or CIF destination terms. Export documentation commonly includes a commercial invoice, packing list, certificate of origin, and any product‑specific test reports (e.g., IPC‑A‑600 visual inspection, X‑ray inspection for inner layers). Importers in the EU frequently demand a CE Declaration of Conformity, while US buyers may request UL listing or FCC compliance for electronic modules. The Chinese export environment for PCBs benefits from well‑developed port facilities and a mature supply chain for raw materials such as FR‑4 laminates and copper foil.

Sourcing from Ke You Pcb Co., Ltd - Buyer Guidance

When sourcing from this supplier, request a detailed material data sheet that specifies substrate type (e.g., FR‑4), copper weight, layer count, surface finish, solder mask color and any compliance certificates (RoHS, IEC 60601 for medical boards). Obtain an IPC‑A‑600 visual inspection report and, if applicable, an X‑ray or ICT (In‑Circuit Test) report to verify internal layer quality before confirming a large order.

Typical minimum order quantities for prototype boards are as low as one unit, while production runs often start at 100 pcs for double‑side or rigid‑flex boards. Lead times range from 2‑4 weeks for standard prototypes to 4‑8 weeks for multi‑layer or fully populated PCBA assemblies, depending on material availability and testing requirements. Verify packaging details - anti‑static bags, desiccants, and carton dimensions - to ensure safe transport, and confirm the Incoterm (e.g., FOB Shanghai) to align logistics responsibilities.

What PCB types does Ke You Pcb Co., Ltd list in its catalogue?

The supplier lists seven items: ENIG charger PCB, Bluetooth earphone ENIG PCB, Uric Acid Meter PCBA, rigid‑flex PCB, double‑side rigid prototype board, generic PCBA assembly, and USB charger PCB assembly offered as OEM.

Which surface finish is used on the charger and earphone boards?

Both the charger and Bluetooth earphone boards are specified with ENIG (Electroless Nickel Immersion Gold) finish, a common choice for reliable solderability and corrosion resistance.

Are there any certifications mentioned for these PCBs?

The supplier’s facts do not list specific certifications; buyers should request ISO 9001, RoHS, UL or CE certificates as appropriate for their target market.

What material and copper specifications are typical for the listed rigid‑flex and double‑side boards?

Typical specifications include an FR‑4 substrate, 1 oz (35 µm) copper per layer, trace widths down to 6 mil, and compliance with IPC‑2221 design standards.

Which HS codes are relevant for importing these products?

Printed circuit boards from China are usually declared under HS chapter 85, with codes 8542.31 for single‑sided, 8542.32 for double‑sided, and 8542.33 for multilayer or rigid‑flex boards.

What documentation should a buyer request before placing a large order?

Buyers should ask for a material data sheet, IPC‑A‑600 visual inspection report, RoHS compliance statement, and any applicable safety certifications such as IEC 60601 for medical PCBA or IEC 60950 for power modules.

What are the typical packaging and shipping methods for these PCBs?
