Import Ceramics Substrate — Buy in wholesale FOB from Supplier in China

The product is a ceramics substrate that can be produced from a range of ceramic materials including alumina, aluminum nitride, zirconia and ferrite, each offering distinct electrical and thermal characteristics. The supplier lists thickness options from 0.1 mm up to 2 mm, a minimum feature size of 0.01 mm and dimensional tolerances between 5 µm and 20 µm depending on the overall size. Shapes are not limited and can be supplied as circles, triangles, rectangles, hexagons or any CAD‑defined polygon, allowing designers flexibility in layout.

In the industry, alumina substrates typically exhibit a dielectric constant of about 9.8 and a thermal conductivity near 25 W m‑¹ K‑¹, while aluminum nitride substrates provide higher conductivity around 170 W m‑¹ K‑¹, useful for high‑power electronics. Typical flexural strength for 99.9 % alumina is roughly 350 MPa, and standard surface finish is polished to a roughness of Ra ≤ 0.2 µm to support thin‑film processes. Commonly, multilayer constructions are used for microwave dielectric applications, where a dielectric constant of 9 - 10 and low loss tangent are required for base‑station equipment and intelligent transport systems.

Buyers such as LED manufacturers, power‑electronics firms and microwave circuit designers source these substrates for their high thermal conductivity and stable dielectric properties. The listing does not disclose minimum order quantities, exact pricing, Incoterms or lead times, so interested parties should request those details directly from the supplier. Confirmation of any specific certifications - for example, ISO 9001 or IPC standards - is also advisable before finalising a purchase.

Walthy Precision Co., Ltd. is based at No.19 Aigeho Road, Weitang, Suzhou, Jiangsu 215000, China. The company holds a harbour‑level trust tier, indicating a verified status, though the response rate shown is 0 % and average response time is not recorded. The profile does not provide the year of establishment, staff numbers or revenue, and no specific certifications are listed.

The supplier specialises in technical ceramics, offering custom‑manufactured substrates that combine ceramic material processing with metallisation techniques. Their capabilities include microwave dielectric, thin‑film and thick‑film substrates, as well as metallised variants for RF and optical applications. No additional services such as assembly or testing are described, so buyers should confirm whether the supplier can provide required post‑processing or inspection services.
