1 Layer - 64 Layer Rigid Flex PCB Assembly Custom Multi Layer PCBA ISO Certified

HTF delivers advanced multilayer rigid-flex circuit board manufacturing with industry-leading 1–64 layer capability, serving as a premier printed circuit board assembly manufacturer for demanding electronic applications worldwide. Our state-of-the-art fabrication facility in Guangdong, China is equipped with automated laser direct imaging systems, precision drilling stations, and vacuum lamination presses capable of producing high-layer-count rigid-flex boards with exceptional registration accuracy and impedance control. From simple 2-layer prototypes to complex 64-layer HDI stackups with blind and buried vias, every board is fabricated to IPC Class 2 and Class 3 standards with full process documentation and traceability. Our engineering team brings extensive experience in managing signal integrity challenges, thermal management requirements, and mechanical reliability considerations inherent in high-layer-count designs, providing design-for-manufacturing feedback that optimizes yield and reduces time-to-market for your projects.

• 1–64 Layer Range: Full spectrum manufacturing capability from single-sided boards to 64-layer rigid-flex assemblies, covering all intermediate layer counts with consistent process control.
• HDI Technology: Advanced HDI fabrication with laser-drilled microvias, stacked and staggered via structures, and via-in-pad designs supporting component densities up to 0.3 mm pitch BGAs.
• Impedance Control: Precision impedance management with ±5% tolerance on controlled-impedance traces, supporting high-speed digital interfaces including PCIe, DDR4/5, USB 3.2, and HDMI 2.1 standards.
• Rigid-Flex Integration: Seamless transition between rigid and flexible sections using polyimide flexible cores laminated with FR4 rigid outer layers, eliminating connectors and improving reliability in space-constrained designs.
• Material Versatility: Support for standard FR4, high-Tg FR4 (170°C and 180°C), halogen-free laminates, polyimide flex cores, aluminum substrates, and Rogers high-frequency materials for RF applications.
• Copper Weight Options: Standard 1 oz copper with available options from 0.5 oz for fine-pitch traces to 6 oz for high-current power distribution planes requiring heavy copper processing.
• Blind & Buried Via: Multiple sequential lamination cycles supporting complex via architectures including stacked microvias, skip vias, and back-drilled through-holes for minimal stub effects in high-speed designs.

Our 1–64 layer rigid-flex PCB assemblies serve mission-critical applications across diverse technology sectors. In telecommunications infrastructure, our high-layer-count boards support 5G base station equipment, optical networking modules, and high-speed backplane systems requiring stringent impedance control and signal integrity management. Aerospace and defense contractors utilize our rigid-flex assemblies in satellite communication payloads, avionics systems, and radar signal processing units where weight reduction, three-dimensional packaging, and high reliability are non-negotiable requirements. Medical device manufacturers depend on our multilayer boards for CT and MRI imaging systems, portable ultrasound devices, and implantable medical electronics that demand biocompatible materials and Class 3 manufacturing standards. Advanced computing applications including AI accelerator cards, FPGA development platforms, and edge computing nodes leverage our HDI and high-layer-count capabilities for dense component placement and thermal management. Industrial IoT gateways, robotics controllers, and automated test equipment systems rely on our boards for reliable operation in electrically noisy, temperature-extreme environments.

All multilayer rigid-flex boards are subjected to 100% automated optical inspection, in-circuit testing, and functional testing according to customer-provided test specifications before shipment. We also perform cross-section analysis on first-article samples to verify layer-to-layer registration, plating thickness, and lamination integrity. Finished boards are vacuum-sealed in anti-static packaging with humidity indicator cards and desiccant, then packed in custom-fitted foam inserts within reinforced double-wall cartons. Single unit packaging measures 59.0×42.0×14.0 cm at 0.5 kg gross weight. Our ISO 9001:2015 certified quality system governs every process step from incoming material inspection through final outgoing quality control, while our ISO 14001:2015 environmental management certification ensures responsible handling of process chemicals and waste streams in full compliance with RoHS and CE regulatory requirements.
