Import Double-Sided Pcbs — Buy in Bulk from Supplier in China

Double-sided printed circuit boards from Shenzhen Jiuan Electronics Technology Co. are manufactured using FR-4 substrate with a standard thickness of 1.6mm and 1 oz copper weight on both layers. The boards feature lead-free HASL surface finish, green solder mask, and white silkscreen legend. These boards support minimum trace and space of 3 mil, with a minimum hole size of 6 mil and drill-to-metal clearance of 7 mil, suitable for dense component layouts in compact electronics. The supplier confirms compliance with RoHS and UL standards for material safety and environmental handling.

The base material is standard FR-4 epoxy glass, with optional halogen-free and high-Tg variants available upon request. Typical industry tolerances for board thickness are ±10%, and inner layer registration is held to 3 mil as stated. Surface treatments include ENIG, OSP, immersion silver, and immersion tin, allowing flexibility for fine-pitch components and lead-free assembly. These boards are not plated-through hole only but support controlled impedance routing with a tolerance of ±8%, which is critical for high-speed signal integrity in communication and test equipment.

These double-sided PCBs are commonly used in computer motherboards, industrial control systems, medical devices, and telecommunications hardware. Buyers typically order prototypes in quantities of 5 to 50 units and mass production runs from 500 to 10,000 units. Packaging is done in anti-static trays with foam inserts, with each unit weighing approximately 0.1kg. Lead time ranges from 5 to 20 days depending on order volume and production backlog. Delivery is handled via express couriers such as DHL, UPS, and FedEx, or by sea freight for larger shipments.

Shenzhen Jiuan Electronics Technology Co. operates from a registered facility in Bao'an District, Shenzhen, with a harbor trust tier indicating verified physical presence and logistics capability. The supplier is classified as an imported manufacturer, meaning it has been vetted for export readiness and documentation compliance. There is no public data on company history, employee count, or annual revenue. The listing confirms active engagement in PCB and PCBA manufacturing, with capabilities in reverse engineering and component sourcing, but does not list any client names, awards, or certifications beyond RoHS and UL.

The supplier responds to inquiries but has no recorded response rate or average response time, suggesting inconsistent communication. No third-party audit reports or factory photos are provided. The listing does not claim ISO 9001 certification, though ISO 14001 is referenced - this relates to environmental management, not quality systems. Buyers should treat this as a production-focused factory without verified design support or in-house testing labs unless confirmed directly.
