DCT offers more than 20 types of cleaning machines (also custom-made products can be realized). 

PCB cleaning after soldering
Why clean the print circuit boards after soldering?
It ensures that the resulting product has a far longer lifespan and is reliable for longer.  Trends that raise demands on cleanliness in the pick-and-place process

• The general miniaturisation of PCB
• The reduction of operating voltage
• Narrower and smaller component spacing
• Shorter distances between conducting paths
• The rise in the use of electronics in all areas of industry

What are the most common problems?  

•   Corrosion causing leakage current and short circuits  
•   Dendrite formation causing leakage current and short circuits  

What causes these problems?
Flux residue on PCB 

Stencils, misprints and squeegees cleaning

Why to clean stencils, squeegees and misprints of PCB?
51 – 72 % of the errors caused by soldering happen as the result of poor solder paste printing.

What are the most common problems?

• Not enough paste is applied
• Solder joint connection
• Creation of "Solder ball"

What causes these problems?
The residue of old solder paste remaining on the template





Conformal Coating cleaning from coating: pcns, frames and machine parts


Why to remove coating PCB and parts of coating devices?
Coating PCBs: enables the removal of defective components from PCB, re-soldering and coating
Coating frames and parts for coating devices: Makes sure of fully-functioning coating frames and coating technology

What are the most common problems?
PCBs: failure of components on PCB during the lifespan of a product
& dendrite formation and corrosion beneath the coating and resulting leakage current and short circuits

Coating frames and parts of coating devices: Layers of hardened coating blocking coating device frames and parts so that the coating process is not 100 % possible.

Cleaning of filters of reflow ovens and waves, soldering frames cleaning

Why to clean filters, coolers and soldering frames?
To ensure a stability of the soldering profile and extend the life of parts

What are the most common problems?
Filters and parts of soldering technology: incorrect functioning of filters, coolers, and other parts, affecting of circulation of air and setting of solder profile

Soldering frames: incorrect position of PCB in the frame, no functions of clamps and fixation springs

What causes these problems?
Flux and other residue from the soldering process
