Modern electronics would be unthinkable without printed circuit boards: As the backbone of electronic devices, PCBs ensure the successful integration of many components such as capacitors, resistors and power supply connections. PCBs make many things possible - if the quality is right. And this is exactly what we at Lacon Electronic have been emphasising for over 40 years.
Our strengths are your advantages

Bigger, faster, further - the demand for assembled PCBs is constantly increasing. That's why we at Lacon Electronic equip modern PCBs with surface-mounted components (SMD). And thanks to our partially or fully automated assembly lines, we guarantee our customers an optimised high-mix / low-mid volume service portfolio. Because what counts in the end is that you are satisfied and realise a successful project with us.
Printed circuit boards from Lacon - manufactured in Europe, globally competitive
Is surface mounting (SMT) worthwhile in Asia? We at Lacon Electronic answer this question with genuine manufacturer quality "Made in Germany" - at absolutely competitive prices, by the way. In general, manufacturers of complex electronics carefully weigh up long transport routes and costs as well as possible delivery delays.
With our concept of off-line upgrading of feeder benches, we enable short, fast routes with high productivity in the SMT sector - with international sourcing and, above all, without the risks of outsourcing production to the Far East.
Your advantages of SMT assembly
- SMT with high flexibility
- 1 to 10 million units in shift operation
- Availability monitoring and obsolescence management for all active components (on request)
- High process reliability: all test procedures possible, traceability of assemblies
- 100% quality inspection of all assemblies
- Sample and prototype production
- Availability within one week in the DACH region (Germany, Austria and Switzerland)
Our traceability concept: transparency throughout the entire production process
Our fully automatic machines achieve a resilient average of 35,000 components per hour - with excellent quality. Thanks to our in-house developed traceability concept, we ensure the best possible traceability of the raw material: during the entire production process of the assemblies right down to the component level ("trace up" and "trace down").
Our SMT machinery makes it possible
We operate 3 lines plus stand-alone machines: for prototyping, the production of small series and sample construction.

Through-hole technology is the manual assembly technique of choice for wired components. Even today, it is still primarily used for assembling PCBs with different components that are exposed to high loads - in addition to connectors and relays, these include power coils and semiconductors or electrolytic capacitors.
Mixed assembly
SMT meets THT
95% of all assemblies in industrial and power electronics are mixed assemblies. This means that both SMT and THT are used for assembly. For this purpose, Lacon Electronic has integrated HEEB laser light spot tables into the part line production. The components are prepared directly in the department: Bending, cutting, beading and programming of IC components of all kinds. A transponder system ensures that assemblies can be identified at any time and at any point in production.
Your advantages of THT and mixed assembly
- Continuous staff training
- Certified soldering personnel
- Mixed assembly soldering in one operation
- Transponder system line assembly
- Military technology (leaded solutions)
- Minimisation of set-up and one-off costs
- Customised fixture construction
- Prototyping and sample production
Our machinery for your wire assembly
We operate a wide range of assembly machines so that we can guarantee a smooth process and maximum efficiency for our customers. Because your success is our goal.

Prototype and customised production
Customised special assemblies
We love hand-assembled printed circuit boards! Do you too? We sit down at the workbench for many essential components: prototypes, development samples, complicated components and old assemblies that are required in small quantities. Because we are constantly working to provide you with exactly the PCBs that will drive your project and your business forward in the long term.
Play in the top league with us: Our testing systems are well-known and popular throughout Europe - we have set new standards in the field of production testing and inspection. And so that we can guarantee our usual high Lacon quality in the long term, we have developed a rigid control system.
Zero-defect strategy for quality control
We can dispense with random samples, as every item we manufacture is carefully checked and tested. During our inspections, we check the completeness of all components such as electrolytic capacitors, connectors, sockets and IC polarity. We carry out solder joint check-ups on unsoldered components and protruding elements (tombstone effect). Throughout the entire process, traceability at component level is particularly important to us.
Our test device: AOI system TR7500QE
As an algorithm-based system, the TR7500QE AOI system from TRI Innovation measures precise physical and optical features of assemblies - in contrast to an image-based system. This minimises the occurrence of false calls (erroneously reported defects). This is because components are checked using clear target data and not simply by comparing component images (manually selected good samples).
The TR7500QE AOI system offers you
- 3D high-performance inspection of solder paste and assemblies through pioneering combination of 2D + 3D
- Adaptive digital 4-way fringe pattern projection
- 3D height range up to 20 mm
- high-speed image acquisition with CoaXPress
- customised templates for zero defect slippage on all assemblies
Advantages of the algorithm-based AOI system
- High accuracy and repeatability of measurements
- Low number of false calls, even with high volumes
- Exponential reduction in programming effort - with increasing operating time
- Use of precisely defined component characteristics for good/bad differentiation
- universal applicability of unique models - for every inspection programme in the library
- High flexibility with precisely programmable tolerances for colours, component sizes and solder joints
- Precise reproducibility of component positions
Conclusion
Quality, innovation and flexibility
With over 40 years of experience, Lacon Electronic stands for the highest quality in the assembly of printed circuit boards.
The IPC-certified team offers SMT and wire assembly, prototype and customised production as well as comprehensive quality assurance, short distances and competitive prices.
Flexible SMT assembly enables the production of 1 to 10 million units in shift operation, supported by a transparent traceability concept.
Quality assurance utilises innovative testing systems such as the efficient TR7500QE AOI system for maximum accuracy and efficiency.
SMT stands for surface mounting technology and describes surface mounting technology for the partially or fully automated assembly of printed circuit boards. In this process, automatic placement machines suck in components that will later be mounted on the PCB and place them on the carrier material.
Through-hole technology involves manual wire assembly of printed circuit boards. In this process, wires with mounted components are cut to the required length. These wire ends of the components are then inserted into the contact holes of the PCB and soldered firmly.
The assembly of printed circuit boards with a combination of SMT and THT is called mixed assembly - this is currently the most common method for the assembly of components.
SMD stands for Surface-Mounted-Device, while SMT is called Surface-Mounting-Technology. In concrete terms, this means that SMT is the technology of surface mounting and SMD is a surface-mounted component.
PCBs - also known as printed circuit boards - can be assembled using various methods. The most common are SMT, THT and mixed assembly. In general, assembly processes of electrical components on a printed circuit board are referred to as mounting - always for use in complex electronic devices.
As the name Electronics Manufacturing Services suggests, EMS service providers plan and manufacture specific electronics.
