We have more than 25 years experience in manufacturing and assembly, and more than 20 years in research and development. Our main focus is to quickly respond to all our customer requirements and needs, and keep maximal satisfaction.

Vesla s.r.o., the main manufacturing plant of the UnitronGroup, is located in the industrial area of Kladno, 20km from Prague, with fast access to the highways R7 and D5 and at only 14km distance from the Prague international airport. The company was founded in 1994 and went through different stages to become the flexible production unit of today.

Currently, more than 1500m² are dedicated to manufacturing activities and about 750m² to warehousing (400 pallets). Our broad range of activities includes: 

  • Purchase and receipt of components
  • Printed board (SMT) assembly services
  • Manual and selective soldering
  • Sheet metal processing
  • Subsystem assembly services
  • Test and measurement
  • Quality control
  • Packaging
  • Warehousing and expedition

Our strength is to offer small and mid-range series at an affordable price and with guaranteed quality: we produce series ranging from a single piece up to high volume production. Based on the ordered quantities a semi-automated or fully-automated test flow is implemented.
For each challenge, we want to be a competent and competitive partner, here follows a summary of our capabilities and approach in some of our departments.

Printed board assembly services
This department is equipped with two modern SMD lines: our main production line JUKI has a screen printer, 4 pick-and-place machines and a reflow oven, it can handle SMD components up to 0201 size. We produce series ranging from single piece up to high volume quantities.
On the output of the SMD lines Automated Optical Inspection (AOI) is implemented.
We can handle the reflow and wave soldering processes.
We have experience in both paste and glue designs.
In this department a strict ESD policy is maintained to guarantee a 100% antistatic (ESD) working environment.


Sheet metal processing
Our multifunctional and reliable machine park allows in-house production of tinned sheet metal covers and frames, all necessary equipment
for cutting, punching, bending and welding is present:

  • Centrifugal pressing machines  (1 x 50 tons, 2 x 40 tons, 3 x 10 tons)
  • Hydraulic pressing machines (2 x 15 tons)
  • 2x Welding machine

Our skilled operators are involved from the start of a customer project and can assist in design for manufacturing, die exchange time reduction and cost-reduction programs.
Our customers always enjoy the luxury of our flexibility and our customer-oriented approach.


Subsystem assembly services
Our operators are continuously trained to accomplish high qualitative assembly of electronic, electrical, mechanical and cabling components using wave or selective, or even manual soldering to offer our customers the most competitive solution.
The performance of our employees is monitored in real-time, continuous improvement is realized by registering all occurring problems and providing
direct visual feedback by Pareto- and control-charts.

Test and measurement
A profound analysis of the customers testing requirements is made during the project transfer phase. Based on this input the optimal test methodology is selected and implemented: manual, semi-automatic or full automatic testing.
It is our aim to offer the best quality at the lowest cost by the correct level of automation, this results in avoiding operator related mistakes and reduces sincerely the needed test times.
Besides RF related tests, other test setups (for example a High-Voltage test stand) are available in Vesla s.r.o.
Our test engineers have built up their experience implementing test setups for our range of RF products. The result is an extensive knowledge of network and spectrum analysers and integrated testbenches (based on National Instruments software).
The results of these automated tests are present in a relational database structure and can be exported to a desired format (html, xml, …)


Where quality is a state-of-mind
Quality of the delivered products is assured through an integrated quality control system:

  • Incoming inspection based on the AQL methodology (quality at the source)
  • In-process testing during the different assembly and testing stages (progressive inspection)
  • Real-time registration and follow-up of non-conformities
  • Outgoing quality control based on the AQL methodology
  • Full product traceability with storage of records up to 20 years
  • Weekly quality meetings to close the feedback loop and assure continuous improvement

We offer our customers flexibility to request other inspection and quality control methods.
Our quality driven approach is supported by our quality management system, Vesla s.r.o. is ISO certified since 1997, currently ISO9001 certified.


Our production line is adapted to deal with large-scale production batches, which ensure low-cost and high quality, but also small scale flawless batch sizes. Our skilled and well trained team is our main capital.

Our slogan is: "Unlimited flexibility, guaranteed quality"
