Assembly technologies
Through Hole Technology
As an optimal complement to fully automatic PCB assembly, we offer conventional Through Hole Technology (THT). This means we are ideally positioned for the often desired mixed assembly of PCBs- with a combination of SMD and THT components.
In THT production, the printed circuit board is assembled manually with great sensitivity. Our experienced employees insert wired components through the contact holes and solder them. In this process, the entire assembly is passed over a hot stream of liquid solder in a wave soldering machine. The solder wave wets the inserted pins with solder, establishing electrical contact with the conductor tracks. We can cover a soldering area of 400 x 400 mm.
For THT solder joints that are difficult to access, for example in double-sided assembly, we use our automatic selective soldering system SPA 440 EVO and manual soldering.
Advantages of selective soldering:
Selective soldering allows THT components to be soldered onto already assembled circuit boards later. The soldering parameters for each solder joint can be set individually.
This means that selective soldering is used primarily when full-surface soldering processes
such as wave soldering are not suitable for process reasons or when high precision and quality are required.
Other advantages of selective soldering are:
- Each solder joint can be individually programmed; flux quantity and soldering time can be precisely adjusted
- High quality of the solder joint (without overheating of components)
- High process reliability and stability
- Low thermal stress for the PCB and adjacent components
- Guaranteed reproducibility
- Increased flexibility: enables the soldering of heavy PCBs that are difficult to process with wave soldering systems.
Compared to the SMT process, the manual THT process is much more time-consuming. Nevertheless, it is still indispensable for certain components, such as plugs and switches.
Application examples
SMT-Surface Mounting Technology
Fully automatic circuit board assembly
With the SMT production line, we can manufacture compact and highly individual PCBs for you in the shortest possible time – and at an excellent price-performance ratio.
We are able to produce printed circuit boards up to a size of 500 x 500 mm as standard. However, larger assemblies are also possible by arrangement.
Placement capacity: up to 30,000 components per hour.
Your advantages through SMT production at miunske:
- Miniaturization: significant reduction in size and weight of the printed circuit boards
- Lower costs due to flexible PCB design and technology (SMT and THT)
- Improvement of the high-frequency properties due to the smaller component spacing
- Shorter production times through automated SMD assembly
- Highest product quality through AOI (automatic optical inspection) and flying probe test system
- Excellent price-performance ratio, especially for small batches
- Sufficient capacity reserves - also for short-term appointment services
"With our new SMT production line, we will be able to offer customers even greater flexibility and customization options in the future. "
Press-fit Technology
In addition to THT and SMT assembly, miunske also offers press-fit technology with its own components, particularly for the manufacture of high-performance components in compact designs. That is why you can expect even more robust and customized electronic components from miunske® in the future.
Advantages of press-fit technology:
- Minimization of the installation space through even more compact components
- Low contact resistances, especially with high continuous current loads
- High resistance to climatic and mechanical stresses
- Minimal risk of failure, e.g. due to cold solder joints
- Environmentally friendly, due to the absence of solder and flux or lead-free materials
