Import 24 Layers High Density Interconnect Pcb, Hdi — Buy in Bulk from Supplier in China

Hitech Circuits produces 24 layer high-density interconnect (HDI) PCBs from their Shenzhen facility, specialising in fine-pitch designs for complex electronics. The boards support 36 layer builds with step lamination (3+N+3 architecture), minimum line width and spacing of 0.05 mm (2 mil), and annular ring down to 0.1 mm. Via diameter starts at 0.1 mm and maximum panel size reaches 500 x 800 mm, enabling compact, multi-functional assemblies for telecommunications, computing and industrial control equipment.

Construction uses FR4 substrate with High Tg 220 resin, offering thermal stability for demanding applications. Material thickness begins at 25 microns above copper, with copper weights ranging from 0.3 to 10 ounce per square foot (10 to 350 microns). This layup supports both signal and power distribution across 24 densely routed layers, accommodating buried and blind vias for signal integrity and impedance control. The combination of material grade and layer count suits prototypes through medium-volume production runs.

Buyers typically source these boards for medical devices, aerospace subsystems, automotive control modules and RF components where signal density and thermal performance are critical. Orders ship from Guangdong, with lead times and tooling costs dependent on design complexity and order volume. Confirm design file requirements, layer stackup specifications, solder mask colour, silkscreen options and finish type (HASL, immersion gold, or OSP) directly with Hitech Circuits before placing purchase orders.

Hitech Circuits Co., Limited operates from Songgang, Bao'an, Shenzhen in Guangdong Province, China, an established manufacturing hub for PCB production. The facility is registered in the harbour trust tier, though real-time response metrics show zero recorded responses; buyers should anticipate initial contact delays and should reach out with technical drawings, volume requirements and lead-time expectations clearly stated. The listing does not disclose ISO certifications, years in operation or production capacity, so these details must be confirmed during early supplier dialogue.
