Import 8l, Fr4, 1.6mm, Blue Soldermask — Buy in Bulk from Supplier in China

This 8-layer FR4 printed circuit board from Shenzhen Hemeixin Electronic Co., Ltd. measures 335 mm x 245 mm with a finished board thickness of 1.6 mm and copper foil weight of 1 oz across all layers. The blue soldermask provides visual contrast for inspection and component placement, while the FR4 laminate base offers the dielectric stability required for multilayer signal integrity. These are the exact dimensions and layer count stated in the listing data.

FR4 is a glass-reinforced epoxy laminate standard in the PCB industry, with a typical glass transition temperature (Tg) of 130-140°C for standard grades and 170-180°C for high-Tg variants. The 8-layer stackup allows dedicated power and ground planes, reducing crosstalk and improving electromagnetic compatibility in dense designs. The 1.6 mm total thickness is the most common standard for industrial and commercial electronics, balancing mechanical rigidity with connector compatibility. Typical dielectric constant for FR4 at 1 GHz ranges from 4.2 to 4.5, with dissipation factor around 0.02.

Applications include telecommunications infrastructure, industrial automation controllers, automotive ECUs, and consumer electronics where compact multilayer routing is essential. Buyers should confirm layer stackup details, impedance control requirements, and surface finish options with Shenzhen Hemeixin Electronic Co., Ltd. directly. The supplier's location in Shenzhen's Shajing industrial zone places it within the Pearl River Delta electronics manufacturing cluster, though no verification status or response history is recorded in the available data.

Shenzhen Hemeixin Electronic Co., Ltd. is located at South Of 5th Floor, 7 Building, Wanxia Industrial Park, Tongfuyu Industrial Area, Shajing St., Shenzhen 518101, Guangdong, China. The supplier carries a 'harbor' trust tier and an 'imported' supplier tier in the platform's classification system. No response rate or average response time data is available; the response rate is recorded as 0.00 with zero average response hours.

The listing does not state the year of establishment, factory size, employee count, annual revenue, specific client references, or ISO/CE certificate numbers. Any such details would need direct confirmation from the supplier. The address places the company in Shenzhen's Bao'an District, a dense concentration of PCB fabricators and electronics assembly operations. Buyers should verify production capabilities, quality certifications, and engineering support levels before placing orders.
