Read MoreAs a critical hub in Central and Eastern Europe (CEE), Hungary has evolved into an industrial powerhouse for automotive assemblies, clean energy electronics, and machinery manufacturing. Major global automotive and technology companies have established massive production plants in Hungary, establishing a complex supply chain that demands highly reliable electronic manufacturing services (EMS).
With the rapid rise of Electric Vehicles (EVs), intelligent grid integrations, and IoT-driven factories, local procurement departments are constantly challenged by scaling capacity, navigating component supply bottlenecks, and finding manufacturing partners that meet stringent European standards (such as CE, RoHS, and specialized certifications like IATF 16949 for automotive or ISO 13485 for medical systems).
This is where a high-efficiency Chinese factory matches the Hungarian market's requirements. By pairing Shenzhen's unparalleled raw material and component sourcing speed with global delivery structures, companies get the best of both worlds: rapid time-to-market and reliable quality.
Shenzhen STHL is a premier provider of Electronics Manufacturing Services (EMS) based in China. We serve customers worldwide along the entire industry chain, including PCB layout, components sourcing, PCB fabrication, PCBA assembly, cable assembly, box build assembly, and comprehensive testing services.
Established in 2006, our 20 years of experience in electronics contract assembly manufacturing backs our capability to handle demanding designs. Today, STHL has a team of over 220 professionals working in our state-of-the-art 10,000 square meter facility.
We operate 7 SMT assembly lines, 2 DIP/THT lines, 2 functional testing lines, and 2 finished device assembly lines. Our customer base spans key global markets including Germany, USA, Italy, UK, Poland, Turkey, Korea, Thailand, and of course, growing partners in Hungary.
As an IATF 16949, ISO 9001, ISO 14001, and ISO 13485 certified electronic assembly manufacturer, our products fully comply with RoHS and REACH standards.
We are equipped to handle complex high-density components on multi-layer configurations:
Robust mechanical bonding for high-power, high-vibration systems like automotive and energy grids:
By handling every step from design check to final delivery, we minimize delay risks and maintain rigorous control over every stage of assembly.
STHL operates 7 automated PCB assembly lines for both prototype and mass production. Advanced SMT ensures precise component placement and quality. Skilled technicians provide efficient THT assembly and RoHS-compliant lead-free soldering.
STHL PCB fabrication service produces high-quality, reliable printed circuit boards from simple singles to complex multi-layers, from flex PCB to rigid-flex PCB, we use premium materials and controlled processes to meet precise specifications.
STHL offer global electronic component sourcing and supply chain solutions. Our vast supplier network and expertise ensure access to genuine, certified parts, mitigating risks of counterfeits, allocation, and long lead times to secure your production schedule.
With the precision manufacturing of cable assembly components including handles, retention systems, connectors, and shielding in a wide range of materials and finishes, we have performed many successful cable assemblies for many customers from various industrial applications.
Making your projects at STHL from SMT assembly to box build assembly is very cost-effective and fast to market. Covering everything from putting a PCBA into the enclosure with all functions testing to a complete product assembly packaged and ready for delivery to your customers, we can supply full support.
STHL conducts functional testing (FCT) to verify product performance, preventing defects such as circuit issues, missing or incorrect components. This ensures delivered products are stable and fully qualified.
Procuring PCBAs for industrial projects requires balancing material costs, lead times, and engineering flexibility. For Hungarian businesses, partnering with a Chinese supplier offers several strategic advantages:
Our direct connections to major component hubs allow us to source standard and hard-to-find components quickly, reducing delays from raw material shortages.
With 7 automated SMT lines, we can easily scale production from low-volume prototypes to high-volume manufacturing runs as your design moves into the market.
We maintain quality through international standards, including IATF 16949 (Automotive), ISO 13485 (Medical), and ISO 9001, providing consistent output across batches.

Review technical and logistical information regarding ordering and importing customized PCBA assemblies into the Hungarian and wider European markets.
Prototype fabrication and SMT/THT assembly typically take 5 to 10 working days after component availability is confirmed. Mass production orders generally require 3 to 4 weeks, depending on component lead times and volume. Air freight to Budapest Liszt Ferenc International Airport averages 3 to 5 days, while sea freight via major European ports takes 30 to 45 days.
Yes. All materials, solder pastes, and finishes we use comply with RoHS and REACH standards. We hold active IATF 16949, ISO 9001, ISO 14001, and ISO 13485 certifications, allowing us to supply components for highly regulated industries such as automotive, healthcare, and industrial safety in Europe.
We procure parts directly from authorized global distributors like Digi-Key, Mouser, Arrow, and Future Electronics. For local sourcing in China, we work exclusively with certified tier-1 distributors. Each incoming batch goes through incoming quality inspection, is labeled with tracking codes, and is stored under controlled ESD and temperature conditions.
We require standard Gerber files (RS-274X format), a detailed Bill of Materials (BOM) in Excel format containing part numbers, values, footprints, and designators, as well as clear assembly drawings or 3D step files. If functional testing (FCT) is required, please provide a testing manual or custom jig specifications.
If an Engineering Change Order (ECO) is submitted, our engineers halt production on the affected batch immediately to evaluate the change. We analyze component changes, stencil adjustments, and firmware updates, and update our documentation before resuming work.
