Large PCB Fabrication Manufacturer
Large PCB Fabrication Manufacturer: Triangle Labs, Inc.
Triangle Labs, Inc. is an award-winning, ISO 9001:2015-certified PCB fabrication manufacturer engineering high-performance, large-format printed circuit boards (PCBs) and printed wiring boards (PWBs) for the most demanding electronic applications in the world. From our facility at 6101 Morgan Mill Rd. in Carson City, Nevada, we fabricate mission-critical, high-frequency circuits built to the strict reliability requirements of the defense, aerospace, and medical sectors.
Our specialty is the intersection of scale and signal integrity: complex RF and microwave circuits on panels other fabricators cannot process. Anchored in deep IPC-6018 expertise, Triangle Labs bridges prototype development and high-volume production for transmission circuits spanning 300 MHz to over 100 GHz, on panels as large as 48″ × 144″.

Large-Format PCB Fabrication Manufacturer: Triangle Labs, Inc.
Why Triangle Labs Is a Different Kind of PCB Fabrication Manufacturer
Most circuit board shops optimize for standard-format, digital work. Triangle Labs is built around the opposite: large-format panels, exotic high-frequency substrates, and tolerances that hold across dimensions where most equipment loses registration.
Three capabilities define our position in the market:
- Large-format fabrication up to 48″ × 144″ – a rare capability that lets us produce antenna arrays, radar assemblies, and microwave circuits as single continuous panels rather than tiled sections.
- High-frequency RF/microwave specialization – full IPC-6018 qualification across all types and classes, with materials and processes purpose-built for signal integrity at millimeter-wave frequencies.
- Precision Laser Direct Imaging (LDI) at panel scale – imaging fine geometry accurately across a 48″ × 96″ panel, holding line-and-space resolution that large-format work normally sacrifices.
These are not incremental advantages. They determine which programs a fabricator can support at all. When a design calls for a continuous large-format microwave panel with 2-mil geometry and controlled impedance, the field of qualified suppliers narrows sharply, and Triangle Labs is in it.
Large-Format PCB Fabrication (Up to 48″ × 144″)
Large-format PCB fabrication is our signature capability. We routinely produce boards and panels up to 48″ × 96″ as a standard offering and extend to 48″ × 144″ for expanded-format requirements.
Fabricating at this scale as a single panel eliminates the seams, connectors, and stitched interfaces that degrade performance in tiled assemblies. For phased-array antennas, radar apertures, and large microwave backplanes, a continuous panel preserves electrical continuity and mechanical stability across the full aperture, a direct contributor to reliability in fielded systems.
Maintaining registration and geometry across a panel of this size is the hard part of the problem. It is solved not with a single tool but with a coordinated process built around Dynamic Registration through LDI, custom-built drilling and routing platforms, and non-contact metrology accurate to fractions of a mil.
High-Frequency RF & Microwave PCB Capabilities
Triangle Labs’ core technical competency is IPC-6018, the qualification and performance specification for high-frequency microwave printed boards. We fabricate to all IPC-6018 types and classes and produce transmission circuits across the full 300 MHz to 100+ GHz range.
Our RF and microwave process capabilities include:
- Microstrip, stripline, and multilayer microwave circuits
- Mixed-dielectric hybrid constructions (for example, Teflon/FR4 assemblies)
- Single-plane and mixed-signal designs
- Conductive paste, plated cavities, and buried metal-core constructions
- Formed and conformal PCBs
- Passive and active designs
- Aluminum and copper base materials with externally mounted heatsinks for thermal management
At high frequency, small deviations in conductor geometry translate directly into insertion loss and phase shift. Our process is engineered to hold conductor dimensions and layer-to-layer registration tightly enough to keep those deviations out of the signal path.
Detailed Manufacturing Capabilities
Triangle Labs supports advanced feature sets that place us among the most capable printed circuit board PCB fabrication manufacturers for high-reliability work:
- Line widths / gaps: 2 mil / 2 mil minimum
- Minimum hole diameter: 0.004″
- Plating aspect ratio: 10:1 for 0.008″-diameter PTH; copper 5 oz.+; filled vias
- Board thickness: up to 0.650″, including thin-core dielectrics
- Heavy copper: up to 40 oz.
- Layer count: 60+ layers for complex multilayer aerospace and commercial designs
- Embedded passives: printed resistors (±5%) and buried passive components
- Specialty processes: Ticer and Ohmega-Ply embedded-resistor technology; Rohacell and DIAB structural foam fabrication
Every board is supported by in-house milling, bonding, optical CMM measurement and inspection, cross-section analysis, and integrated coupon testing. Custom tolerances beyond our published specifications are available on request, a reflection of an engineering-led process rather than a fixed catalog of standard stackups.

Precision Equipment & Technology
A capability is only as reliable as the equipment behind it. Triangle Labs has invested in a toolset matched to large-format, high-frequency work:
- Precision LDI (Laser Direct Imaging): A 48″ × 96″ precision LDI system, believed to be the only one of its size in the world, enabling 0.002″/0.002″ lines and spaces across the full large-format panel. A second, dual-head 39″ × 39″ LDI unit performs simultaneous double-sided imaging, also at sub-2-mil resolution.
- Schmoll-Maschinen driller/routers: Custom-built drilling and routing platforms among the most advanced in the industry.
- PLURITEC MEGA driller/routers: A 50″ × 114″ platform sized for large-format panels.
- Chemcut clean / develop / etch / strip line: A 48″-wide wet-process line, upgraded in 2017.
- Optical / non-contact CMM: Metrology accurate to 0.00001″, used for print verification, quality control, and First Article reporting.
Dynamic Registration through LDI is central to holding layer-to-layer accuracy at high frequency. By imaging each layer to the actual position of the material rather than a fixed reference, we mitigate the signal loss and phase shift that result from conductor geometry deviation, the failure mode that most often limits large-format microwave yield.
Materials & Supplier Relationships
High-frequency performance begins with the substrate. Triangle Labs processes copper-clad laminates and prepreg bonding materials from the leading names in RF and microwave materials, including Rogers, Arlon, AGC (Nelco/Taconic), Taconic, and Isola.
We are also an exclusive fabrication specialist for Rohacell, the closed-cell structural foam used to build lightweight microstrip patch antennas for satellite communication and other weight-sensitive aerospace and defense applications. Precision machining of Rohacell and DIAB structural foams supports designs where mass, dielectric performance, and mechanical stability must all be optimized together.
While we recommend proven high-frequency laminates, we fabricate with materials from any supplier a customer’s design requires. Material selection is treated as an engineering decision, not a procurement default.
Markets Served
Triangle Labs supports programs where circuit board failure is not an option:
- Aerospace: large-format microwave circuits, antenna structures, and multilayer assemblies for airborne and space systems
- Defense: radar, electronic warfare, and communications hardware built to defense reliability standards
- Medical: high-frequency and high-reliability circuits for critical medical electronics

Our work as a PCB fabrication manufacturer has supported Raytheon AESA radar systems, including the AN/APG-82(V1) and AN/APG-79, with performance feedback attributed to the Raytheon SAS and Raytheon SEAC groups. Delivering into Tier 1 defense radar programs is a direct measure of a fabricator’s qualification, process control, and consistency.
Engineering Support Services
Triangle Labs functions as an engineering partner, not just a build house. Our team provides support on-site, at customer facilities, or via net conferencing across:
- Design for Manufacturability (DFM)
- Design for Reliability (DFR)
- Cost vs. performance analysis
- Material selection analysis and development
- RF organic substrates
- Composite and hybrid applications
- Signal integrity
- Thermal analysis
- Mixed surface coatings
