Rogers HDI PCB Boards — Heavy Copper & Multilayer

HDI stands for High Density Interconnect. It refers to a PCB technology characterized by a higher wiring density per unit area than conventional boards. HDI PCBs use laser drilling (microvias), blind and buried vias, and fine-line trace geometries to achieve miniaturization and improved electrical performance — critical for advanced applications requiring tight impedance control and multi-layer signal routing.

Rogers material refers to high-frequency laminates manufactured by Rogers Corporation, used as an alternative to standard FR4. These advanced dielectric materials offer low signal loss, stable dielectric constant across a wide frequency range, and excellent thermal management. They are preferred in RF, microwave, and high-speed digital applications within aerospace, defense, telecommunications, and medical device electronics.

SFX PCB's Rogers HDI boards support up to 20 total layers. The stack-up can incorporate Rogers dielectric layers alongside FR4 or Polyimide layers for hybrid constructions, enabling complex signal routing, controlled impedance of +/-10%, and laser drilling down to 4mil — suitable for demanding multilayer designs in aerospace, military, and high-frequency telecom systems.

Available surface finishes include ENIG (Electroless Nickel Immersion Gold), Immersion Silver, Immersion Tin, OSP (Organic Solderability Preservative), ENEPIG, Soft Gold, and Hard Gold Plating. Each finish offers different benefits for solderability, corrosion resistance, and wire-bonding compatibility. SFX PCB's engineering team can recommend the optimal finish based on your application's performance and environmental requirements.

Every Rogers HDI bare board undergoes 100% electrical testing, automated optical inspection (AOI), and flying probe testing. Assembled boards are further verified through X-ray inspection, AOI, and functional testing (FCT). SFX PCB also provides free DFM (Design for Manufacturability) analysis prior to production to identify and resolve potential reliability issues before manufacturing begins.

SFX PCB accommodates both prototype and high-volume orders with no fixed minimum quantity constraints. Prototype PCBs can be assembled as quickly as 24 hours once all components are available. Lead times for production runs vary based on layer count, complexity, and volume.
