Import Aluminum Base Board(Al-Base Pcb) — Buy in Bulk from Supplier in China

Oak Cream Electronic Co., Ltd. manufactures aluminum base printed circuit boards (Al-base PCBs) with 1.5mm board thickness and standard 1oz copper foil, featuring minimum hole sizes of 0.2mm and fine line capability for intricate layouts. The base material is aluminum, selected for its thermal conductivity advantage over standard FR-4 substrates in heat-generating applications. The supplier operates from Changsha, Hunan Province, China, with a harbor trust tier and imported supplier tier classification.

Aluminum base PCBs typically employ aluminum alloy 5052 or 6061 as the metal substrate, with a dielectric layer of thermally conductive epoxy or polyimide bonding the copper circuit to the aluminum base. Standard thermal conductivity for this construction ranges from 1.0 to 3.0 W/m·K for the dielectric layer, though the bulk aluminum substrate itself conducts approximately 160-200 W/m·K. The 1oz copper (approximately 35 micrometers thickness) provides current carrying capacity of roughly 3.5-4.0 A per 10mm trace width at standard temperature rise, though exact values depend on trace geometry and cooling conditions. Surface finish options typically include HASL, ENIG, OSP, or immersion tin, though buyers should confirm which finishes Oak Cream supports.

Primary applications include LED lighting modules, power supply converters, motor drivers, and audio amplifiers where heat dissipation prevents LED degradation or semiconductor thermal runaway. The telecommunications, automotive, and consumer electronics industries represent the core buyer segments. Buyers should confirm with Oak Cream whether they offer single-sided, double-sided, or multilayer Al-PCB constructions, as capability varies significantly between manufacturers. The supplier mentions ISO and CE certifications, though specific scope and validity should be verified directly. Packaging and shipping terms require confirmation, as the source description indicates flexibility without stating standard practice.

Oak Cream Electronic Co., Ltd. is located at Composite Building, Oak Park High-Tech Development Zone, Yuelu District, Changsha 410025, Hunan Province, China. The supplier holds both harbor trust tier and imported supplier tier designations, with a 0.00% response rate and zero recorded average response hours, indicating limited or no response data on the platform. No information is provided about year of establishment, factory floor space, employee count, or annual revenue.

The company positions itself as a manufacturer of industrial-grade aluminum base PCBs for telecommunications, automotive, and consumer electronics markets. The source description references verified suppliers and competitive pricing, though these appear to be platform marketing phrases rather than specific claims about Oak Cream's own verification status or pricing structure. Buyers should independently assess production capability through factory audit or video verification, as the available profile provides minimal operational detail beyond the Changsha address and general product description.
