6 Layer PCB Manufacturer for Precision Fabrication

A 6 layer PCB contains six conductive copper layers laminated within a single board, providing higher wiring density, more routing channels, and better signal integrity than a 4 layer PCB. The additional layers allow for dedicated power, ground, and signal planes, enabling support for blind and buried vias, impedance control, and more complex circuit designs in a compact form factor.

SFX PCB's 6 layer PCBs are primarily fabricated on FR4 substrate with copper weights ranging from 0.5oz to 10oz per layer and board thicknesses from 0.6mm to 10mm. Surface finishes including HASL, ENIG, and OSP are available. Premium material options such as Rogers, High Tg, and Halogen-Free variants can be specified for specialized high-frequency or high-temperature applications.

SFX PCB supports a minimum line width and spacing of 0.07mm (approximately 2.76 mil) for 6 layer PCBs. Minimum hole size is 0.15mm, and both blind and buried vias are supported. These tight tolerances enable high-density interconnect designs suited to compact, performance-critical electronics.

Yes, impedance control is a standard capability for SFX PCB's 6 layer boards. This is essential for high-speed digital circuits, RF applications, and signal transmission systems where consistent characteristic impedance across traces prevents reflections, signal degradation, and EMI issues. Customers should specify impedance requirements when submitting design files.

SFX PCB holds ISO 9001, ISO 14001, and ISO 13485 certifications, along with UL listing and IPC-A-610 Class 2/3 compliance. All 6 layer PCBs are manufactured under RoHS and REACH compliance standards, ensuring suitability for global markets including the EU, North America, and Asia-Pacific regions.

6 layer PCBs are widely used in telecommunications equipment for high-speed data transmission, medical devices requiring precise signal processing, industrial control and automation systems, automotive electronics, aerospace applications, and consumer electronics such as smartphones and computers. Their dense routing capability makes them suitable for any application demanding complex multilayer circuit integration.

Yes. SFX PCB accepts Gerber files, Eagle files, and native PCB design files. Customers are encouraged to submit complete design packages including drill files and stackup information. A free DFM (Design for Manufacturability) analysis is performed on every order to identify potential faults before production begins, reducing costly rework. Quotes are provided within 24 hours of file submission.
