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 agents 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.
How our systems/machines work and what are their main advantages - see our PCB cleaning procedure.
Or take a look at our case studies about PCB cleaning.
Our cleaning fluids will help you avoid these problems.

InJet® 388 CRD
InJet® 388 CRD is developed primarily for the removalof solder pastes and SMT adhesives from stencils, PumPrints,squeegees and misprints. The cleaning system can also be used for PCB cleaning, or for a combination of PCB cleaning and the afore-mentioned cleaning processes. The machine can also be used for the removal of cured conformal coating.
Technical data sheet►InJet® 388 CRRD Combo
The InJet® 388 CRRD “Combo” is primarily designed for precision plate cleaning after soldering. The cleaning system can also be used for high-quality removal of solder pastes and SMT adhesives from stencils, PumpPrint, squeegees and misprint, or the aforementioned cleaning applications, along with cleaning the boards after soldering. It is also possible to use the machine to remove the cured conformal coating.
Technical data sheet►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.
Technical data sheet►InJet® 3179 CRD BigBoard
InJet® 3179 CRD is designed to remove solder pastes and SMT adhesives from non-standard large stencils up to 100 x 1700 x 900 mm or 3.94 x 66.93 x 35.43 in, respectively. The process chamber's size also allows inserting and simultaneously cleaning 2 standard 29 ”x 29” stencils. The InJet® 3179 CRD includes 100% closed-loop withprocesses of cleaning, rinsing, and drying technologies. All the processes are fully automated, and take place in one process chamber.
Technical data sheet►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.
Technical data sheet►InJet® 888 CRRD 2F
The InJet® 888 CRRD-2F is designed primarily for removing flux residues from PCB. It is possible to insert and clean a stencil or misprints at the same time. The 2F designation refers to a 2-storey solution where smaller parts can be cleaned in two baskets simultaneously to maximize cleaning capacity. After easy removal of the rotation arm, large parts can be cleaned in one (lower) basket.
Technical data sheet►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.
Technical data sheet►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.
Technical data sheet►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.
Technical data sheet►External filtration
Large-capacity external filtration, made completely of stainless steel, is another of a number of unique solutions for filtering of rinse water from the production of DCT Czech s.r.o. The system uses the sandwich filtration continuously connected in three filter tanks. These are interconnected by stainless steel distribution pipes and placed on a separate structure with rollers, which ensures trouble-free handling and the possibility of connecting to any type of cleaning system from the production of DCT Czech. Easy maintenance and service are commonplace without any disassembly.
