Import 6-Layer Hdi F4b Pcb — Buy in Bulk from Supplier in China

The 6-Layer HDI F4B PCB from Shenzhen Longxiang Intellectual Technology Co., Ltd. is a high-density interconnect printed circuit board built on F4B substrate, a low-loss fluoropolymer composite material valued in RF and microwave applications. The board measures 1.6mm in finished thickness with minimum trace width and space of 3.5mil (0.089mm) and minimum drilled hole size of 0.15mm (6mil). This construction employs blind and buried vias to achieve denser routing in a compact footprint than conventional through-hole multilayer designs.

F4B material exhibits a typical dielectric constant of 2.65 and dissipation factor below 0.003 at 10GHz, making it suitable for 5G base stations, satellite communications, and radar systems where signal integrity at microwave frequencies is critical. The six-layer stackup allows dedicated power and ground planes with controlled impedance on signal layers. Copper thickness options range from 0.5oz to 6oz (17.5 to 210 micrometres), with inner-layer copper greater than 18 micrometres in plated through-holes. Surface finish choices include immersion gold (ENIG), immersion silver, immersion tin, lead-free HASL, and OSP, selected according to assembly process and shelf-life requirements.

Shenzhen Longxiang Intellectual Technology Co., Ltd. manufactures this board at their facility in Baoan District, Shenzhen, with maximum panel size of 580 x 900mm and outline tolerance of plus or minus 0.13mm. Target markets include projector manufacturers, telecommunications equipment producers, and aerospace contractors requiring impedance control and via-plugging capabilities. OEM and assembly services are offered alongside bare board fabrication. Buyers should confirm current lead times, minimum order quantities, and whether UL file and TS16949:2002 certification documentation is active and current, as the source description references these marks without verification of validity.

Shenzhen Longxiang Intellectual Technology Co., Ltd. is located at Room 318, Zhihuichuangxin Center, Qianjin 2Road, Xixiang, Baoan District, Shenzhen 518101, Guangdong, China. The company holds a harbour trust tier with a 0.00% response rate and zero recorded average response hours, suggesting that platform-mediated enquiries may not receive prompt replies. Buyers are encouraged to contact the company directly at their Baoan District address for technical discussions and quotation requests.

The source description references UL marking and TS16949:2002 certification without providing certificate numbers, scope, or expiration dates, so buyers must independently verify the current validity of these claims. No information is given about year of establishment, production floor space, number of employees, annual revenue, or major customers. The listing does indicate capability across 1 to 28 layer counts and multiple material systems (FR-4, CEM-3, high Tg, halogen-free FR4, Rogers, and F4B), which suggests a flexible manufacturing operation rather than a single-product facility. Request a facility audit or third-party manufacturing assessment before committing to volume orders.
