Precise cleaning by de-smearing

Our de-smear systems provide you with perfect chemical cleaning processes. Individually customized to the wishes of our customers, we build efficient machines for maximum precision de-smearing. In this way, they create the foundation for high-quality, reliable and high-performance printed circuit boards. 

• Thorough cleaning and preparation of the glass fibers. 
• Reliable borehole activation 
• Optimization of electrical properties 
• Indispensable for multilayers 

All-round carefree service

To ensure that our machines continue to work perfectly even after many years, we offer our customers a high-performance and experienced service. Whether maintenance, wear, repair or modernization, the TSK service ensures reliable production at all times. 
In addition, we also take care of machines for horizontal wet chemical processes that do not come from our company. Feel free to ask us!  

Central in PCB construction

De-smear systems play a central role in the production process of printed circuit boards. They carefully remove any residue that is created during the drilling of the plates. Caused by the thermal and mechanical stress on the starting material during drilling, these residues can impair the adhesion of the metal layer that will be applied later. The de-smear system cleans the base material and activates the borehole walls evenly. This ensures reliable preparation for the subsequent contacting of the conductive layers in the circuit board and lays the foundation for high-quality and functional printed circuit boards. 

Optimising electrical properties

De-smear plants combine chemical and physical processes. In a multi-stage process, they remove resin residues caused during drilling and prepare the base material for subsequent metallization. This is usually done by chemical treatment. The swelling of the resin forms the preliminary stage, whereby an oxidizing solution first roughens the borehole walls and then neutralizes them. An even and, above all, dense and homogeneous layer formation in the drill holes ensures better adhesion of the metal that will be applied later. This improves the surface structure of the bore in order to create electrical conductivity for the subsequent plating process. 

Indispensable for high quality

TSK design systems can be found in the production of complex printed circuit boards, for example in automotive, telecommunications and consumer electronics. Especially for multilayer PCBs, which consist of several layers, the de-smear technique is indispensable. It ensures that the different layers can be safely connected to each other by means of boreholes. The use of de-smear systems significantly increases reliability and performance in the subsequent through-hole process of the printed circuit boards. Every via, combined with the high quality requirements, therefore makes the de-smear process indispensable. 

Perfect cleaning

De-smear systems from TSK meet the highest standards of function, precision and durability. In close cooperation with our customers and the respective chemical manufacturers in combination with your base materials, we develop your de-smear plant exactly according to your requirements. Precisely manufactured from TSK you get de-smear systems that deliver perfect results over the long term. 
In addition to the de-smear machines and vias, we offer all common measurement and analysis methods to keep the chemistry as efficient as possible. These include area and piece counters, regeneration units and conductivity measurements. The regeneration cells to oxidize manganate back are integrated in the module sump and reduce leaks.  

Continuously refine technologies

For TSK, the state of the art is always only the basis and starting point for making further technological advances and refining technologies. In doing so, we always keep in mind that our systems are easy to maintain and robust in order to reliably maintain production. Resource conservation and environmental friendliness, wastewater-saving circuits, emissions into the air and noise emissions are just as important to us as the production quality for which the machines were designed. We support our customers in obtaining operator approvals for the processes on site.
