Cleaning Applications

Stencil, Misprint and Squeegee

Machine cleaning of stencils and squeegees is an essential cleaning process in SMT for perfectly cleaned stencils and especially its apertures. Improper cleaning of stencils leads to misprints, which have to be discarded or cleaned from incorrectly applied solder paste. Thanks to our cleaning processes, we can clean also the misprints, so the PCB can be used again.

PCB Cleaning

Cleaning of PCB after soldering is an actual topic because of the increasing demands of the electronics industry, especially in areas of security, automotive, healthcare, aviation, aerospace, military, or measuring technologies. Poorly cleaned PCBAs can cause the failure of electronics. Cleaning of PCBA is also an important step before the coating process.

Our products 

Maintenance Cleaning

Maintenance cleaning of machines and other equipment is a preventive cleaning process in electronics production, which prevents problems during mounting and soldering. Without machine cleaning of filtres from soldering ovens and waves, soldering frames, masks, or transport carriages the production process can not be effective and the quality can not be sustainable.

Our products 

Conformal Coating Cleaning

Removal of conformal coating is demanding cleaning application since the coating is a durable material. The cleaning is done during the maintenance of coating frames and machine parts for maintaining the high quality of SMT production. It is possible to remove the coatings from PCB as well in case of repair. We clean acrylic, polyurethane, epoxy, silicone …

Manual Cleaning

Manual cleaning is an ordinary part of the production processes of electronics. It is done during the maintenance cleaning of the inner parts of soldering ovens, waves, and other machine parts from flux residues. It is possible to clean manually stencils as well in case of small volume production. Another area of manual cleaning is the removal of flux from PCBa during the repair.

Our products 

Under Stencil Cleaning

Cleaning of the underside of the stencil directly in the SMT printers is important for the precise application of soldering paste on PCB. Appropriate cleaning chemistry and a good process set up can shorten the time of production and lower the costs. We develop cleaning agents for this cleaning application on a water and alcohol basis.

Tyco ElectronicsRadek Matuška
Process Engineer

Our company, Tyco Fire Protection Products, focuses on manufacturing and services in the field of fire protection. With the transfer to lead-free soldering, we have encountered issues with the cleaning efficiency of PCBs after the reflow process. Thanks to our long-term cooperation with DCT Czech, their professional approach to our cleaning needs, their flexibility and customer oriented and user-friend solutions, we were able to successfully modify and implement a new vertical spraying PCB cleaning process. DCT Czech developed and manufactured a high-capacity cleaning system, which we have been successfully using for nearly two years.

David Joura CEO

All technologies are useless if you miss the courage.

The birth of our company in 2001 was preceded by great courage - to act and make dreams come true. And today, we try to give the same space for self-fulfillment to our employees, too. There is almost 100 of us in the company now, and having left the former horse barn where we had started then, we moved to a spacious industrial building in Boskovice. However, the growth of the company brings along responsibility: for employees and clients from 36 countries in every corner of our planet. Our desire to improve thus never ends. We learn and improve every day to be one of the best companies in the sector of cleaning technologies in the electrical engineering industry.

Zbyněk Zukal CSO, Co-Owner

Our success is based on nothing more than the everyday hard work of the entire DCT team and an effort to be the best supplier of cleaning technologies for the electronics industry in the world.

Since the very beginning, the very first customer, the very first application we encountered, we have focused on one fundamental thing: helping new customers improve their existing and future cleaning processes technically, economically, and comprehensively. We have created a unique business and service model built on good personal knowledge of our customers and their real needs. We have implemented this model over the past 20+ years in more than 36+ countries with more than 700+ customers.
