Advanced PCB Assembly
Advanced PCB assembly means tighter tolerances, denser designs, and no margin for error. We're talking 10+ layer stacks, micro BGAs, blind vias, and mixed signal routing. These are the builds behind high-tech medical devices, aerospace controls, advanced robotics, and RF systems.
At Ninja Circuits, this is our comfort zone. We specialize in turning these complex assemblies quickly so your team can keep testing, refining, and pushing forward. Our engineers work directly with you on stackups, placement, and BOM files to lock in every detail before a single board hits the bench. You get precision builds, responsive support, and fast U.S.-based delivery from day one. If you're developing what's next, we’re ready to help you build it faster.
Advanced PCBA Applications
PCBA PROTOTYPING
Prototypes are what we do every day. Our goal is to provide you with quality products that will validate your designs in as short a period of time as possible. Our staff can source all the components for your design, or provide labor only builds if you have all the components, or a combination of both. Let us know what you need.
PCB ASSEMBLY
Are you looking for a one-time build to bridge the gap between old and new products? Or perhaps support for legacy products? Ninja can provide you with fast turn options tailored to your needs that will help minimize your inventory requirements and still service your customers efficiently.
REPAIRS, UPGRADES, REPLACEMENTS
If you need assistance with a product already assembled, Ninja can help. Component upgrade or replacement, modifications, repairs, Ninja personnel have the skills and experience and equipment to help bring your existing product to the desired configuration.
SHORT-RUN PRODUCTION
Do you need to bring your product to market but your electronics manufacturer can't ramp up fast enough? Ninja can meet your short-run needs with fast turnaround of quantities to fit your demand.
Advanced PCBA Applications
Advanced PCB assemblies are the backbone of leading edge technology systems in aerospace, defense, medical, and automation fields. These boards manage sensor data in unmanned vehicles, control feedback loops in surgical robotics, and handle high-speed signal routing in next-gen telecom. They're built for speed, accuracy, and repeatability (often under strict compliance requirements).
Our boards are application-specific builds, shaped around your layout constraints, environmental conditions, and electrical demands. Fine-pitch QFNs, tight trace spacing, mixed signal routing, rigid-flex hybrids, we’ve seen it all, and we build them fast. Clients come to us when the standard fab house says no or when the next design review is breathing down their neck. If the challenge is technical, time-sensitive, or both, you’ve met your match.
Testing Standards
Precision begins at inspection. Every high tech PCB assembly undergoes a tailored quality control process based on build complexity, component density, and regulatory class. Testing protocols include:
- Microscope-level visual inspection for solder joint integrity and placement accuracy
- 3D Automated Optical Inspection (3D AOI) to identify opens, shorts, and coplanarity issues
- X-ray imaging for internal verification of BGAs, QFNs, and other leadless packages
- Electrical test procedures using flying probe or custom fixture setups for continuity and isolation checks
- Adherence to IPC-A-610 Class II and III standards based on product requirements
- ITAR-controlled processes and serialized documentation upon request

Testing is integrated from the start, aligned to your performance specs and compliance requirements.
THE NINJA WAY
Ninja Circuits is a flexible, fast, and skilled pcb assembly manufacturer dedicated to developing the best and quickest pcb assembly prototypes in the USA. We offer exceptionally fast pcb assembly prototypes to engineers and innovators developing new products to improve and enhance our lives and the world we live in. Ninja Circuits is proud to be based in the USA, which allows Ninja Circuits to provide excellent communication, on-time delivery, quick turn PCB assembly, and responsive customer service.
Flexible
Flexibility is our strength. No two customers are alike. Ninja will tailor our services to your needs to provide you with the desired outcome for your project.
Fast
Ninja Circuits knows that the culmination of your project design is a working prototype. Waiting weeks or months for validation is not only frustrating but impedes schedules and time to market and is unacceptable. Ninja can provide you a quality product in as short amount of time possible.
SKILLED
Our personnel are trained with skills on par with anyone in the EMS industry. A poorly assembled product is a failure. Ninja delivers fast AND quality products every day and will ensure your project needs are met.
OUR certifications
Ninja Circuits is committed to providing quality to customers. Certifications, training, and experience are what we take pride in at every step of the way for every project.
WHAT OUR CUSTOMERS SAY
We appreciated the quick and creative response you provided in building this product. I was concerned about the robustness of this assembly, but you found a solution that secured the components in the box sufficiently.

Sometimes the layout isn't final. Sometimes the part you need is backordered. Sometimes the schedule just doesn’t care. We get it. Advanced PCB assembly rarely happens under perfect conditions, and that’s exactly where we come in.
At Ninja Circuits, we specialize in prototypes, short runs, and edge cases. We offer fast decision-making, flexible turnarounds, and real engineering support. Our team works that way every day. Upload your BOM, share your files, and we’ll help you hit your deadline without sacrificing build quality. Every project starts with a real quote, not guesswork or auto-generated pricing.
