Conformal Coating Cleaning

Conformal Coating Cleaning

The removal of conformal coatings from the surfaces of coating frames, various PCBAs or from coated PCBAs themselves is a very complex cleaning process. Coating manufacturers care about the quality of their products, but they usually do not deal with the subsequent cleaning of different surfaces.

Thorough cleaning of coated parts means that these products can return to service without compromising their functionality and reliability. The reuse of coated parts (frames) in operations results in total cost savings of purchasing these items. The second complex process is the complete or partial removal of coatings from coated PCBA surfaces, their repair and subsequent return to service.

Overall, conformal coating cleaning is very complicated and our agents achieve very good results in this area.

Since the opening of our new facility, we added both the InJet®388 for cleaning stencils and AirJet®594 for washing reflow heat exchangers. We requested multiple custom design changes for the InJet and DCT worked with us to modify the machine accordingly. We run 24/7 and have had exceptional service with DCT night/day/weekend. The machines are built very well and we haven’t had any major hardware or software issues for the last 2 years.

At Tyco Fire Protection Products, our primary focus is on fire protection products and services. With the transition to lead-free soldering, we have struggled with the quality of washdown results for PCBs after the soldering process. Thanks to our long-standing relationship with DCT Czech, their expertise in cleaning, flexibility and customer solution orientation, we successfully changed and implemented a new PCB cleaning process using vertical spraying. DCT Czech designed and manufactured a high-capacity cleaning system for us, which we have been using successfully for almost 2 years.

DCT Czech helped us to solve the application of cleaning the printing templates from the residues of solder paste and SMT glue and at the same time cleaning the soldered PCBs from the residues of flux. After implementing the new Injet 388 mCRD cleaning technology and Decotron CP381 cleaning agent, it is possible to clean all parts in one cleaning machine with one type of cleaning fluid. A comprehensive solution has thus been achieved that ensures long-term stable cleaning results. We are also working with DCT Czech to improve other cleaning processes in our production.

We have been cooperating with DCT since 2006. We use DCT washing processes for cleaning: stencils, PCB overprints, soldering frames, filters from reflow ovens and also for manual cleaning. We are very happy and satisfied with our cooperation with DCT. We appreciate the support directly from DCT, but also from local DCT specialists.

Continental Automotive Czech Republic – Frenštát pod Radhoštěm is assembling PCBs for a major automotive client that requires maximum reliability of all its parts. Due to these high quality requirements, we were looking for a suitable supplier who could set up the entire cleaning process after soldering these PCBs. By working with DCT, we were able to gradually eliminate most of the technical problems associated with the cleanliness of the parts and satisfy a very demanding customer. What we appreciate most about our cooperation is the expertise of the DCT team and their ability to flexibly address emerging technical issues and the more stringent requirements of the end customer.
