Many electronics require a mix of SMT and through-hole (DIP) components, and Leskovac Electronic Solutions (LES) specializes in this hybrid assembly. Located in Leskovac, in southern Serbia, LES has mastered the art of combining fine-pitch SMT parts with larger DIP components like connectors, transformers, and electrolytic capacitors—common in industrial controls, power supplies, and audio equipment.
LES's facility includes two SMT lines and two manual DIP stations with wave soldering, allowing them to handle complex boards with both technologies. They also offer selective soldering for through-hole components on densely populated PCBs, ensuring precision without damaging SMT parts. Their
PCBA testing process
includes hipot testing (for high-voltage boards) and in-circuit testing to verify both SMT and DIP connections. LES provides turnkey solutions, from component sourcing to final assembly, and uses
component management software
to track lead times for long-lead components, preventing production delays. Certified to ISO 9001 and IPC-A-610, LES is known for its problem-solving skills—when a client needed a PCB with 50+ DIP components and 0201 SMT parts, LES engineers redesigned the assembly process to ensure both technologies were placed accurately. Their flexibility makes them a top choice for industries with mixed-technology needs.
Industrial environments are tough on electronics—dust, moisture, vibration, and extreme temperatures can quickly degrade PCBs. Užice Tech Partners (UTP), based in Užice, Serbia, specializes in ruggedized PCBA for industrial applications, including factory automation, oil and gas sensors, and renewable energy systems.
UTP's expertise lies in protective coatings and encapsulation. They offer conformal coating (acrylic, silicone, urethane), potting (for complete environmental sealing), and custom enclosures designed to withstand IP67/IP68 ratings (dust and water resistance). Their SMT lines handle large, heavy components (up to 500g) and thick PCBs (up to 3.2mm), common in industrial equipment. Certified to ATEX (for explosive atmospheres) and ISO 9001, UTP tests boards under simulated industrial conditions, such as 1,000-hour salt spray testing and 50G vibration testing. Their
component management software
prioritizes sourcing industrial-grade components with wide temperature ranges (-55°C to +125°C) and long lifecycles, critical for equipment with 10+ year service lives. Clients often partner with UTP for their engineering support—they help redesign commercial off-the-shelf (COTS) boards for industrial use, adding ruggedization features like reinforced connectors and thermal management.
Rounding out our list is Sombor Electronics Manufacturing (SEM), a agile supplier specializing in low-volume, high-mix PCBA. Based in Sombor, near the Croatian border, SEM serves clients in niche industries: aerospace, defense, scientific instruments, and custom industrial controls—sectors where product runs are small (10–1,000 units) but requirements are highly specialized.
SEM's strength is customization. They don't just assemble PCBs; they work with clients to design test fixtures, develop custom soldering processes for unique components, and even source obsolete parts for legacy equipment. Their
component management software
includes a global network of brokers and distributors, allowing them to find rare or end-of-life components that other suppliers can't. SEM offers flexible lead times (as little as 1 week for urgent orders) and prototype-to-production services, making them ideal for small businesses and research institutions. While they're smaller than some competitors, SEM maintains high quality—each board undergoes manual inspection by a senior technician, and functional testing is tailored to the client's specifications. Certified to ISO 9001 and RoHS compliant, SEM prides itself on being a "problem-solving partner" rather than just a manufacturer. Clients often say they stay with SEM for years because of their willingness to take on challenging projects that larger suppliers decline.
