With a 10,000 sq. ft. facility in Sant Julià de Lòria, they specialize in conformal coating for consumer electronics—think smartwatches, Bluetooth speakers, and IoT devices. What makes AEC stand out is their speed: they can coat up to 50,000 PCBs per day using automated dip and spray lines, making them a go-to for clients with tight deadlines. But speed doesn't mean cutting corners. AEC uses 3D inspection systems to check coating thickness (target: 25-50 microns) on every batch, ensuring compliance with IPC-CC-830 standards. "Our clients are under pressure to launch products before competitors," says production manager Elena Gomez. "We take that pressure off by (promising) 48-hour turnaround for urgent orders." AEC also partners with local SMT assembly houses, offering "coating as part of the assembly line" services—saving clients time and logistics hassle. For mass production with zero compromises, AEC delivers.

MicroCoat Andorra is for the innovators—clients working on cutting-edge tech that demands microscopic precision. This niche supplier specializes in ultra-thin conformal coatings (as thin as 5 microns) for microelectronics, like wearables and medical implants. Their secret weapon? A custom-built electrostatic spray system that can coat individual components without masking, reducing waste and improving efficiency. "Traditional masking tape can leave residue or damage tiny components," explains founder Dr. Pierre Dubois, a materials science expert. "Our system uses charged particles to 'wrap' the coating around components, so we don't need masks." MicroCoat also offers R&D services, helping clients develop custom coating formulations for unique challenges (e.g., biocompatible coatings for implantable devices). While they're smaller than some competitors, their expertise has earned them partnerships with universities and tech startups across Europe. If your project pushes the boundaries of what's possible, MicroCoat will push right alongside you.
