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.
| Layer Count | 4 |
| Surface Treatment | OSP (Organic Surface Preservation) |
| Soldermask Color | Green |
| Silkscreen Color | Yellow |
| Final Board Thickness | 1.60 mm |
| Copper Thickness | Typical 1 oz (35 µm) for inner and outer layers (confirm with supplier) |
| Material | FR-4 (typical for 4-layer PCBs; confirm with supplier) |
| Minimum Trace Width/Spacing | Standard 4 mil/4 mil for high-density designs (confirm with supplier) |
| Operating Temperature Range | -40°C to +125°C (typical for FR-4 PCBs) |
| Flammability Rating | UL 94V-0 (typical for FR-4; confirm with supplier) |
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.

Sourcing 4 layer OSP circuit board from Ume E - Technology Co., Ltd. - China Import Guide
Before placing an order, verify the PCB’s compliance with your industry’s standards, such as IPC-6012 for performance or RoHS for environmental restrictions. Confirm the exact material (e.g., FR-4) and its properties, as these impact electrical performance and reliability. Request samples for prototype testing to validate compatibility with your design.
For logistics, clarify the Incoterms offered by Ume E - Technology Co., Ltd., as Chinese suppliers often default to FOB Shenzhen or CIF to major ports. Lead times can vary based on production capacity and shipping method, so confirm estimated delivery windows and preferred carriers. Payment terms such as T/T or L/C should be negotiated, along with any applicable import duties or taxes in your country.
Quality checks should include inspecting the OSP finish for uniformity and solderability, as well as verifying the board thickness and layer alignment. Request a first-article inspection report to confirm the specifications match your requirements. Ensure the PCBs are packaged to prevent moisture absorption and physical damage, and confirm if the supplier provides a warranty for defects or failures during the intended use period.
