Multilayer PCB Design for High-Speed Signal Integrity

SFX PCB supports layer counts ranging from 4 layers up to 68 layers for rigid FR4 PCBs, and up to 20 layers for rigid-flex configurations. Custom layer stack-ups are available to meet specific signal integrity, impedance, shielding, and thermal management requirements for each unique application.

Available substrates include standard FR4, High Tg FR4 (Tg150/170/180), Rogers RO4000 series (RO4003C, RO4350B) for low-loss RF and microwave applications, polyimide for flexible boards, ceramic (ALN, Al2O3) for high-power thermal management, and specialty materials from Isola, Ventec, and Arlon for demanding aerospace and military applications.

Impedance control ensures transmission line impedance matches design targets, preventing signal reflections and degradation at high speeds. SFX PCB supports impedance-controlled manufacturing across its 6-layer PCB, multilayer PCB, rigid FR4 PCB, rigid flex PCB, and flex PCB product lines, with tight tolerances achievable depending on material and layer configuration.

SFX PCB holds ISO9001 (quality management), ISO14001 (environmental management), and ISO13485 (medical device manufacturing) certifications. Production also conforms to IPC-A-610 Class 2 and Class 3 standards, with RoHS and REACH compliance across applicable product lines, and UL listing for the Rigid FR4 PCB range.

Yes. SFX PCB supports both blind vias and buried vias in its multilayer PCB and 6-layer PCB product lines. These advanced via structures enable higher routing density, reduced signal path lengths, and improved signal integrity — essential for miniaturized, high-speed digital and RF circuit designs.
