Import Bluetooth Earphone Enig Pcb Circuit Board — Buy in wholesale FOB from Supplier in China

Ke You Pcb Co., Ltd manufactures Bluetooth earphone ENIG PCB circuit boards using electroless nickel immersion gold surface finish, a configuration preferred in consumer audio devices for its flat coplanar pads, multiple reflow cycle durability, and reliable wire bonding characteristics. The company's SMT capability spans nine lines, five equipped with Yamaha pick-and-place systems and four with KME machines, achieving 52 million component placements per month. Maximum board size handled is 457mm by 356mm, with minimum component size capability down to 0201 passives and support for fine-pitch QFP, CSP and BGA packages.

The ENIG finish on this Bluetooth earphone PCB provides nickel thickness typically 3 to 5 micrometres and gold thickness 0.05 to 0.1 micrometres, ensuring solder joint reliability and preventing copper oxidation during storage and reflow. PTH (plated through-hole) operations run across axial, radial and jumper wire insertion lines with combined monthly capacity of 21 million points, supported by dual-wave lead-free wave soldering with maximum temperature of 399°C and three pre-heat zones. This infrastructure allows Ke You Pcb Co., Ltd to produce mixed-technology boards combining SMT, through-hole and wave-soldered components in single-pass or dual-sided configurations.

Target buyers include Bluetooth audio OEMs, TWS brand owners, and consumer electronics contract manufacturers seeking PCBA sourcing with documented SMT and PTH capabilities. The Shenzhen location offers proximity to component markets in Huaqiangbei and major south China shipping ports. Importers should verify whether Ke You Pcb Co., Ltd provides full turnkey PCBA (component procurement plus assembly) or consignment-only services, and whether firmware flashing, acoustic testing, or RF calibration are available as value-added steps for finished earphone module delivery.

Ke You Pcb Co., Ltd is located at Room 221, Jinhetian Center in the Qinghu Area of Longhua District, Shenzhen, Guangdong Province, China, placing it within the world's most concentrated electronics manufacturing ecosystem. The supplier holds a harbor-tier trust designation with a 0.00 percent response rate and zero recorded average response hours, indicating no platform-tracked inquiry history rather than necessarily reflecting current operational status. The address suggests a commercial office or light manufacturing facility rather than a sprawling industrial campus, which is typical for Shenzhen-based PCB trading companies and specialised assembly houses.

The company's disclosed capabilities focus on SMT and PTH assembly rather than bare board fabrication, implying Ke You Pcb Co., Ltd either sources PCB substrates from partner factories or operates as a pure PCBA service provider. No ISO certifications, IPC membership, quality awards, client references, revenue figures, employee headcount, or factory ownership details appear in the available profile. Buyers should conduct on-site audits or third-party verification through agencies such as SGS or Bureau Veritas to confirm production floor existence, equipment condition, and whether the Jinhetian Center location houses manufacturing or serves as a sales office with production at an undisclosed satellite facility.
