Product Details High-density interconnect PCB technology is used for electronic products that require compact board structures, high wiring density and controlled high-speed signals. Custom HDI PCBs can combine fine-line routing, laser microvias and multilayer structures to provide more interconnections within a limited PCB area.Rogers high-frequency laminates can be used for applications where stable electrical performance and controlled signal transmission are important. Materials such as Rogers RO4003C and RO4350B can be combined with FR-4 in hybrid PCB constructions, allowing the board structure to balance high-frequency performance with the requirements of the overall product design.The HDI manufacturing process can support 4 to 32 layer PCB structures, including 1+N+1 and any-layer HDI configurations. Laser blind and buried microvias can be produced down to 0.1 mm, while fine-line and fine-space designs can reach 3/3 mil depending on the board structure and manufacturing requirements.Controlled impedance is important for RF circuits, differential signals and high-speed digital interfaces. Single-ended and differential impedance can be controlled within ±5% according to the specified PCB stack-up and design requirements. Impedance verification can be performed during production to check that the manufactured PCB meets the required electrical characteristics.The PCB fabrication process can support ENIG, HASL, OSP and immersion silver surface finishes. The appropriate surface treatment can be selected according to the component assembly process, electrical requirements and expected operating environment.HDI technology also allows designers to reduce PCB size while maintaining a high component and routing density. Laser microvias can connect different PCB layers in compact areas where conventional through-hole vias may consume too much board space.For RF and high-frequency designs, the PCB stack-up, dielectric material, copper thickness, trace geometry and impedance requirements need to be considered together. Rogers materials can be used in selected signal layers, while FR-4 can be incorporated into other layers to create a hybrid multilayer construction.The manufacturing process can include automated optical inspection and impedance verification. These checks help identify PCB fabrication issues and verify critical electrical characteristics before the boards move to the next production stage.Custom HDI PCB manufacturing can be used for 5G communication equipment, RF and microwave modules, IoT gateways, automotive ADAS controllers and medical imaging electronics. These products often require compact circuit boards with controlled impedance and high-density signal routing.The PCB can be manufactured from customer design files such as Gerber or ODB++ data, BOM information, PCB stack-up requirements and impedance specifications. Engineering review can be carried out before production to evaluate manufacturability and the relationship between the PCB layout, materials and required electrical performance.Prototype and volume production can both be supported according to project requirements. The same HDI manufacturing process can be adapted for different layer counts, materials, via structures and impedance requirements, allowing the PCB to be developed for both compact prototypes and production electronic equipment.
