Top 10 PCBA OEM Suppliers in Cuba

Nestled in the heart of Cuba's capital, Havana Electronics Solutions has been a cornerstone of the local electronics scene since 2005. What sets HES apart is its one-stop smt assembly service —they handle everything from PCB design reviews and component sourcing to final testing. Their 15,000 sq. ft. facility is equipped with state-of-the-art SMT lines capable of placing components as small as 01005 (0.4mm x 0.2mm), making them a go-to for high-precision projects.

HES specializes in serving the medical device and industrial automation sectors, where reliability is critical. They're also known for their robust component management system, which uses electronic component management software to track over 50,000 part numbers, ensuring clients never face delays due to stockouts. "We once helped a local medical device startup source a rare microcontroller during the 2022 chip shortage by leveraging our global network," says HES operations manager, Maria Gonzalez. "That's the kind of problem-solving our clients rely on."

Located in Santiago de Cuba, the country's second-largest city, SPAC has built a reputation for affordability without compromising on quality. Founded in 2010, they focus on low cost smt processing service for small to medium enterprises (SMEs) and startups, making them a favorite among local innovators.

SPAC's sweet spot is low to medium volume production (100–10,000 units), with lead times as short as 5 days for prototypes. They offer both SMT and DIP assembly, plus functional testing to ensure boards work right out of the box. What clients love most? Their transparent pricing—no hidden fees, and detailed quotations that break down costs for components, labor, and testing. "We started with a small order of 50 PCBs for a home automation device," says a local entrepreneur. "SPAC not only delivered on time but also suggested cheaper alternative components that didn't affect performance. They treated us like a big client, even when we were just starting out."

Varadero Tech, based in the coastal city of Varadero, is all about precision. Their facility boasts high-end SMT machines with placement accuracy of ±50 microns, making them ideal for projects with tight spacing, like IoT devices and wearables. They're also one of the few suppliers in Cuba offering conformal coating—a protective layer that shields PCBs from moisture, dust, and temperature extremes.

What makes Varadero Tech unique is their focus on turnkey smt pcb assembly service . Clients provide a design file, and Varadero handles the rest: sourcing components (including hard-to-find ICs), assembly, testing, conformal coating, and even packaging. They work closely with global smt contract manufacturing partners to source components, ensuring access to parts from Asia and Europe. "We needed a PCB for a marine sensor that had to withstand saltwater corrosion," explains an engineer from a local environmental firm. "Varadero suggested a silicone conformal coating and sourced a specialized waterproof connector—our sensors have been deployed for two years with zero failures."

Camagüey Precision Circuits, in the central city of Camagüey, is a family-owned business with a focus on customer relationships. Founded in 2008 by two electrical engineers, CPC prides itself on "treating every project like it's our own." They specialize in mixed-technology assembly (combining SMT and DIP components) and offer smt assembly with testing service to catch issues early.

CPC's claim to fame is their component management system. They use electronic component management software to track inventory in real time, allowing clients to reserve parts for future orders and avoid last-minute shortages. They also help manage excess components—if a project is canceled or scaled back, CPC can store or resell unused parts, reducing waste and saving clients money. "We had a batch of 200 PCBs where the design changed mid-production," recalls a client. "CPC stored the excess resistors and capacitors for us, and we used them six months later on another project. That kind of flexibility is rare."

Holguín Electronics Assembly, in eastern Cuba, is a rising star known for its fast turnaround times and low volume smt assembly service . Perfect for startups and R&D teams, HEA can produce prototype PCBs in as little as 48 hours, with no minimum order quantity. Their small but efficient team of 15 technicians focuses on quality, with a 99.7% first-pass yield (meaning almost all boards work correctly on the first try).

HEA also offers design for manufacturing (DFM) reviews—free of charge. Their engineers look at client designs and suggest tweaks to make assembly easier, reduce costs, or improve reliability. "We sent HEA a PCB design that kept failing during testing," says a university researcher. "Their team noticed we'd placed a heat-sensitive component too close to a resistor. They redesigned that section for us, and the next batch worked perfectly. It saved us weeks of frustration."

Santa Clara SMT, in the central city of Santa Clara, is a favorite among industrial clients. They specialize in rugged PCBs for harsh environments—think factory machinery, agricultural sensors, and mining equipment. Their assembly process includes conformal coating and potting (encapsulating boards in resin) for extra durability.

What sets Santa Clara apart is their testing capabilities. They have a dedicated testing lab with equipment for functional testing, in-circuit testing (ICT), and environmental testing (temperature, humidity, vibration). For clients with complex projects, they even build custom test fixtures to automate testing, saving time and reducing human error. "We needed PCBs for a sugar mill conveyor system," says a plant manager. "Santa Clara tested each board under 60°C heat and heavy vibration—exactly the conditions in our factory. Not a single board failed after six months of operation."

Guantánamo PCB Innovations is all about innovation. Based in Guantánamo, they're one of the few suppliers in Cuba offering advanced services like BGA (Ball Grid Array) rework, which is essential for repairing or upgrading complex chips. They also specialize in prototyping for emerging technologies, from AI-powered sensors to renewable energy controllers.

Guantánamo's team includes engineers with backgrounds in electronics design, so they don't just assemble boards—they collaborate on design optimization. "We came to them with a rough sketch for a solar panel optimizer," says a renewable energy startup founder. "Their engineers helped us refine the circuit, choose more efficient components, and even suggested a smaller PCB size that reduced material costs. They turned our idea into a working prototype in three weeks."

Cienfuegos Tech Works, in the historic city of Cienfuegos, is a small but mighty supplier focused on sustainability. They're the only PCBA OEM in Cuba with a zero-waste certification, recycling 95% of their manufacturing waste (scrap metal, solder, packaging). They also prioritize sourcing eco-friendly components, like lead-free solder and halogen-free PCBs.

Cienfuegos specializes in low-volume, high-mix production—great for clients with multiple product lines or frequent design changes. They offer flexible payment terms and small minimum orders (as low as 10 units), making them ideal for startups and educational institutions. "We're a university lab working on multiple research projects," says a professor. "Cienfuegos lets us order 10 PCBs for each project, and they're always patient when we need to tweak the design mid-order. Plus, their commitment to sustainability aligns with our values."
