Ceske Budejovice Welding Services (CBWS) may be the youngest supplier on this list (founded in 2010), but it has quickly made a name for itself with its focus on innovation and customer-centric approach. Located in the southern Czech Republic, CBWS specializes in low-volume, high-mix dip plug-in assembly—making it ideal for startups, R&D teams, and businesses launching new products.

CBWS's claim to fame is its rapid prototyping service. While many suppliers require large minimum orders, CBWS accepts prototype runs of just 1–10 PCBs, with turnaround times as fast as 48 hours. This speed is a game-changer for startups testing new designs or making last-minute adjustments before mass production. "We needed to iterate on three PCB designs in a week, and CBWS delivered each prototype within 2 days—helping us meet our investor deadline," a startup founder recalled.

Despite its focus on small batches, CBWS doesn't skimp on quality. They're ISO 9001 certified and use automated optical inspection (AOI) for every PCB, ensuring that even prototype runs meet industry standards. Their services also include manual dip soldering for delicate components that can't withstand wave soldering, a skill that requires years of expertise. For clients transitioning from prototyping to mass production, CBWS offers seamless scaling, with dedicated project managers to oversee the process.

Liberec Industrial Welding (LIW) is a powerhouse in heavy-duty electronics manufacturing, serving clients in mining, construction, and transportation. Located in the industrial city of Liberec, LIW specializes in dip plug-in assembly for large, rugged PCBs used in harsh environments—think circuit boards that withstand extreme temperatures, vibration, and moisture.

What makes LIW unique is its expertise in soldering large through-hole components, such as capacitors, connectors, and transformers, which are common in industrial equipment. Their wave soldering machines are designed to handle PCBs up to 600mm x 400mm, a size that many suppliers can't accommodate. They also offer post-soldering services like potting and encapsulation, which protect PCBs from environmental damage.

As an ISO 9001 and ISO 45001 (occupational health and safety) certified facility, LIW prioritizes both product and worker well-being. Their rigorous testing process includes thermal cycling, vibration testing, and humidity testing, ensuring that PCBs perform reliably in real-world conditions. "Our mining equipment operates in dusty, high-temperature environments, and LIW's PCBs have lasted 3+ years without failure—far exceeding our expectations," a mining client stated.

LIW's customer base spans Europe and beyond, with export capabilities to 20+ countries. They offer multilingual support (Czech, German, English, and Polish) and flexible shipping options, including express delivery for urgent orders. For businesses needing durable, heavy-duty PCBs, LIW is a trusted partner.
