从China供应商批量进口4 Layer Osp Circuit Board

The 4 layer OSP circuit board from Ume E - Technology Co., Ltd. is engineered for high-performance electronic applications, featuring a four-layer configuration to enhance signal integrity and reliability. The board undergoes OSP (Organic Surface Preservation) treatment, a lead-free process that protects the copper layer while ensuring excellent solderability. With a final thickness of 1.60 mm, it is suited for compact and complex electronic designs.

This PCB includes a green solder mask for durability and environmental protection, paired with a yellow silkscreen for improved component placement visibility. The OSP finish is a standard choice for lead-free manufacturing, common in industries such as telecommunications, consumer electronics, and automotive systems. Typical 4-layer PCBs meet IPC-6012 standards for performance and reliability, though the listing does not explicitly state compliance.

Used in devices requiring precision and reliability, this circuit board is ideal for manufacturers of smartphones, IoT devices, and industrial controls. Buyers sourcing from China should confirm the board’s compliance with international standards such as ISO or CE, as these are often expected but not guaranteed. The supplier’s trade terms include FOB and CIF shipping, with payment options like L/C and T/T, making it adaptable to various procurement processes.

Ume E - Technology Co., Ltd. is located in Room 402, No. 07 West Street, Dong Fuwei Community, Fuyong Town, Bao’an District, Shenzhen, Guangdong, China. This address places the supplier in a well-known electronics manufacturing hub, with Shenzhen being a global center for PCB production and export.

The company holds an 'imported' supplier tier and a 'harbor' trust tier, though the profile indicates a 0.00% response rate and no recorded average response time. This suggests limited recent engagement, so buyers should verify the supplier’s current operational status and responsiveness. The listing mentions ISO and CE certifications, but these are not confirmed in the supplier’s profile, so buyers must request documentation directly.
