Your Partner for High-Mix, Turnkey Solutions

When looking for a partner that balances personalized service with industrial-grade capabilities, Wintech emerges as a top contender. They have carved a niche in the market by focusing on the specific needs of clients who require more than just a board fabrication—they need a complete electronic solution.

Wintech distinguishes itself by being a "one-stop-shop." For startups and established enterprises alike, the ability to hand off a concept and receive a fully assembled, boxed product—including metal fabrication and plastic molding—is invaluable. This holistic approach reduces supply chain friction and ensures that the final product meets rigorous quality standards from the circuit board up to the external enclosure.

The Standard for Quick-Turn Prototypes

Advanced Circuits, often referred to as AdvancedPCB, is a household name in the North American engineering community. Based in Aurora, Colorado, they are celebrated for their "Quick Turn" capabilities, often delivering simple prototype boards in as little as 24 hours. This speed is critical for R&D teams that need to iterate designs rapidly without waiting weeks for offshore shipments.

Beyond speed, Advanced Circuits offers a unique "Bare Bones" service for students and hobbyists, making professional-grade PCBs accessible to a wider audience. However, they are also fully capable of high-reliability production runs, holding certifications for military and aerospace applications (MIL-PRF-31032, AS9100). Their commitment to "Made in USA" is a core part of their identity, ensuring that all manufacturing and customer support remain domestic.

Key Capabilities:

• Same-day and weekend turns for prototypes.
• Free Design for Manufacturability (DFM) checks.
• No minimum order quantity (MOQ) on standard specs.
• Educational discounts for students and universities.

Complex Technology for Mission-Critical Systems

Sanmina is a heavy hitter in the Electronic Manufacturing Services (EMS) industry. Headquartered in San Jose, California, they operate globally but maintain a robust manufacturing footprint in the US. Sanmina is the go-to manufacturer for the most complex and demanding PCBs on the market, such as massive backplanes used in telecommunications infrastructure and high-layer-count boards for medical imaging devices.

Their expertise lies in engineering support. Sanmina doesn't just build to print; they work closely with OEMs to optimize designs for signal integrity and manufacturability. Their capabilities include manufacturing boards with over 70 layers and utilizing exotic materials that standard fab houses cannot handle. If your project involves critical infrastructure or life-support medical devices, Sanmina's rigorous quality systems are designed to mitigate risk.

Key Capabilities:

• High layer count backplanes (up to 70+ layers).
• Optical and RF technology integration.
• Advanced failure analysis labs.
• Vertical integration with mechanical systems.

The Summit of High-Density Interconnects

Summit Interconnect has rapidly grown through strategic acquisitions to become one of the largest privately held PCB manufacturers in North America. Their focus is squarely on the high-reliability sector, serving defense, aerospace, and medical clients. With multiple facilities across California and Toronto, they offer a redundant manufacturing capability that provides supply chain security to their customers.

Summit specializes in difficult-to-manufacture boards, particularly those requiring High-Density Interconnect (HDI) technologies. HDI boards are essential for modern miniaturized electronics, allowing for more components to be placed on smaller boards through the use of blind and buried vias. Summit's investment in laser drilling and direct imaging technology allows them to achieve extremely fine lines and spaces, essential for next-generation electronics.

Key Capabilities:

• Sequential lamination for complex HDI designs.
• Flex and Rigid-Flex fabrication.
• Semiconductor test boards (ATE).
• Thermal management solutions for high-power electronics.

The Prototype and Microelectronics Specialists

Located in the heart of Silicon Valley, Sierra Circuits has been a staple for tech companies since the 1980s. They define themselves by their ability to handle "Micro-electronics" PCBs—boards with extremely tight tolerances and microscopic features. Sierra is often the first stop for Silicon Valley startups looking to prototype the next big wearable or IoT device.

Sierra Circuits emphasizes transparency and education. They provide an extensive library of technical resources and design guides to help engineers create better board layouts. Their proprietary "Turnkey Pro" service allows customers to order fabrication, component procurement, and assembly online instantly, streamlining the prototyping process significantly.

Key Capabilities:

• Micro-PCB manufacturing (trace/space down to 2 mils).
• Controlled impedance and signal integrity analysis.
• In-house assembly for seamless prototyping.
• Specialty materials (Rogers, Polyimide).

Passion and Speed in Fabrication

APCT has differentiated itself with a mantra of "Passion / Commitment / Trust." While this sounds like marketing, their operational model backs it up. They specialize in reducing cycle times for their customers. Where a standard lead time might be 3-4 weeks, APCT excels at delivering complex multi-layer boards in 5-10 days, and standard technologies even faster.

Headquartered in Santa Clara, California, APCT has expanded its footprint to include facilities capable of global volume production management. This means a customer can prototype with APCT in the US for speed, and then utilize APCT's offshore partnerships for cost reduction when moving to mass production, all managed by the same US-based team.

Key Capabilities:

• Quick turn manufacturing for HDI and Rigid-Flex.
• Global supply chain management (Offshore transfer).
• Human-centric customer service approach.
• Diverse material inventory for immediate production.
