PCB cleaning

PCB cleaning
The number of PCBs used in the automotive, healthcare, aviation, communications and other industries is growing rapidly. Ensuring the functional reliability of these modules is therefore very important. Everything is further enhanced by miniaturization of PCBs and their subsequent exposure to climatic influences (humidity, gases, temperature,…).

One solution to future problems is to thoroughly clean the PCB surface after fitting components from flux residues, chemicals and other potentially harmful substances. Thorough use of cleaning liquid on the surface consequently affects other process steps such as conformal coating. Poorly cleaned or uncleaned PCBs can subsequently cause module failure in the final product.

Our cleaning fluids will help you avoid these problems.

InJet® 388 TWIN CRRD Sausage dog

InJet® 388 TWIN CRRD Sausage dog

InJet® 388 TWIN CRRD “Sausage Dog” is developed primarily for high-capacity and precise plate cleaning after soldering. The cleaning system can also be used for high-capacity removal of solder pastes and SMT adhesives from stencils, PumpPrint, squeegees and misprints. Cleaning takes place in the first inlet chamber, after which the cleaned part is automatically transported to the central passage chamber where the first rinsing process takes place. The last third and outlet chambers are for the final rinse and drying process. Both chambers (inlet and outlet) can be used simultaneously, which increases machine capacity and reduces cross-contamination compared to single-chamber systems.

InJet® 388 Triple CRRD

InJet® 388 Triple CRRD

InJet® 388 TRIPLE CRRD is developed primarily for high-capacity and precise plate cleaning after soldering. All processes are fully automated and run in 3 separate process chambers, where the cleaning takes place in the first inlet chamber, then the cleaned part is automatically transported to the central chamber where the first rinsing process takes place. The last third and outlet chambers are for the final rinse and drying process. All 3 chambers can be used in parallel, which increases machine capacity and reduces cross-contamination compared to single-chamber systems.

InJet® 388 Double Triple CRRD

InJet® 388 Double Triple CRRD

InJet® 388 DOUBLE TRIPLE CRRD delivers twice the cleaning capacity of the InJet® 388 TRIPLE CRRD and is, therefore, our most powerful vertical sprayer for post-solder plate cleaning, which has also been developed. The cleaning system can also be used for high-capacity removal of solder pastes and SMT adhesive from stencils, PumpPrint, squeegee and misprint. All processes are fully automated and run in 3 process chambers. Cleaning takes place in the first inlet chamber, after which the cleaned part is automatically transported to the central chamber where the first rinsing process takes place. The last third and outlet chambers are for the final rinse and drying process. All 3 chamber chambers (inlet and outlet) can be used simultaneously, which increases machine capacity and reduces cross-contamination compared to single-chamber equipment. The machine has two positions on the PCB frame (two slots), which means that at full capacity, 6 frames with PCB are simultaneously processed.

1 PR Filtration

1 PR Filtration

This system makes it possible to rinse PCBs or stencil with de-mineralised water with a conductivity of about 0.5 uS and a pressure of 0.2 bar. This gives the customer a precise final rinse during the process itself. The filtration system is firmly attached to the cleaning system structure. This PR FILTRATION (Phase Rinsing Filtration) is a unique filtration system of rinse water developed in DCT Czech s.r.o.

2 PR Filtration

2 PR Filtration

This 2PR FILTRATION (Two-Phase Rinsing Filtration) is a unique filtration system of rinse water developed in DCT Czech s.r.o. This system operates continuously in 2 phases of rinsing. In the 1st phase, rinsing water flows through a mechanical filter with a pressure of 1 bar and a conductivity of 400uS. This phase perfectly removes detergent residues from printed circuit boards or stencils. The 2nd rinsing phase enables the circuit board or the template to be rinsed with demineralized water at a pressure of 0.2 bar and a conductivity of around 0.5uS. This gives the customer a precise rinse during the process. The combination of these phases ensures perfect cleaning of the clean parts. The filter system is firmly connected to the cleaning machine structure.
