Import Black Oil Resistance Pcb — Buy in wholesale FOB from Supplier in China

The Black Oil Resistance PCB from Hk Ct Tech Co., Limited is a 4-layer multilayer board designed for applications requiring enhanced resistance to oil and environmental contaminants. The PCB features a thickness of 0.25mm, with a minimum linewidth of 0.075mm (3mil) and a minimum gap of 0.065mm (2.8mil), enabling high-density interconnects. The black solder mask is applied using a 36T screen, providing a resistance welding oil layer that is 50 tons thicker than traditional 43T screens, improving reliability for fine-pitch components like BGAs.

This PCB supports a minimum aperture internal radius of 0.15mm and a minimum external diameter of 0.45mm, with a minimum BGA pitch of 0.2mm. The board is a through-hole, non-impedance type, making it suitable for general-purpose applications where controlled impedance is not a requirement. The black oil-resistant coating enhances durability in harsh environments, such as automotive or industrial settings where exposure to oils, greases, or solvents is common.

Hk Ct Tech Co., Limited targets buyers in electronics manufacturing, particularly those producing consumer devices, automotive control systems, and industrial equipment. The PCB is ideal for compact designs where space constraints demand fine-line circuitry and reliable solder joints. Buyers should confirm the exact layer stack-up, copper weight, and thermal properties, as these are not specified in the listing. Shipping typically originates from Shenzhen, with lead times and packaging details to be agreed upon during order confirmation.

Hk Ct Tech Co., Limited is based in Shenzhen, China, with its office and production facility located in the Hongfa Technology Industrial Park, Tangtou Community, Baoan District. The company specialises in multilayer PCBs, including high-density interconnect (HDI) and oil-resistant variants, catering to industries such as consumer electronics, automotive, and industrial automation. Its harbor trust tier indicates a baseline level of verified trade activity, but no additional certifications or quality accreditations are stated in the profile.

The supplier’s response metrics currently show a rate of 0.00, with no average response time recorded. This may indicate that direct inquiries require persistent follow-up, and buyers are advised to use multiple contact channels to confirm technical specifications, lead times, and production capabilities. The profile does not disclose details such as annual production volume, workforce size, or export markets, so buyers should request this information directly.
