SMILE can apply both spray and dip conformal coating and has a controlled heat chamber in place for curing temperature and based cure coatings.
SMILE also has experience with potting into product pour & fill. Our mixing and dispensing system can handle any requirement to match volumes with an appropriate amount of potting inventory. We are capable of any mix ratio and have experience with heated compounds.
Our experience ranges with the following:
Conformal Coating in CT
There are many advantages to circuit board conformal coating, including protecting circuitry from moisture, fungus, dust and corrosion caused by extreme environments; preventing damage during handling, installation and use; reducing mechanical stress on components; and protecting the PWA from thermal shock. This is done by coating the board with a layer of transparent coating material, with UV indicators for quality control. We apply coatings using spray, dip and brush methods. The following materials are used for coating:
Potting is the process of enclosing a complete electronic assembly with a solid compound for protection against shock, vibration, moisture and corrosion. This process involves putting the device into a case or shell and then pouring the liquid potting compound to the top of the case covering the device and completely encasing it. While this process is generally more labor-intensive and costly than conformal coating, it does provide a higher degree of water and chemical resistance and electrical insulation. There are several different types of potting compounds useful in various situations, including:
