{465} Conformal Coating - Protect Electronic Circuit Board from Weather effect Plastic70

in this video I discussed what is #conformal #coating. Conformal Coating - Protect Electronic Circuit Board from Weather effect Plastic70. Conformal coating spray is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board's components from weather effect. Typically applied at 25-250 μm (micrometers) thickness, it is applied to electronic circuitry to protect against moisture, dust, chemicals, and temperature extremes. Specially after soldering the board must be cleaned with some contact cleaner, isopropyl alcohol 99.9% or any suitable cleaning solvent material to remove oxides which built at soldering points.
Conformal coating application
Coatings can be applied in a number of ways, including brushing, spraying, dispensing and dip coating. Furthermore, a number of materials can be used as a conformal coating, such as acrylics, silicones, urethanes and parylene. Each has their own characteristics, making them preferred for certain environments and manufacturing scenarios. Most circuit board assembly firms coat assemblies with a layer of transparent conformal coating, which is lighter and easier to inspect than potting
Conformal coatings are used to protect electronic components from the environmental factors they are exposed to. Examples of these factors include moisture, dust, salt, chemicals, temperature changes and mechanical abrasion. Successful conformal coating will prevent the board from corroding. More recently, conformal coatings are being used to reduce the formation of whiskers and can also prevent current bleed between closely positioned components.
Conformal coatings are breathable, allowing trapped moisture in electronic boards to escape while maintaining protection from contamination. These coatings are not sealants, and prolonged exposure to vapors will cause transmission and degradation to occur. There are typically four classes of conformal coatings: Acrylic, Urethane, Silicone, and Varnish. While each has its own specific physical and chemical properties each are able to perform the following functions:
Insulation: Allowing closer conductor spacing
Eliminate the need for complex enclosures
Minimal effect on component weight
Completely protect the assembly against chemical and corrosive attack
Eliminate performance degradation due to environmental hazards
It Minimize environmental stress on a PCB assembly

Many many thanks

[@goosgitaar]

The problem I encountered with this coating is that it becomes difficult to take measurements and do repairs if the board is defective.
So I tried super paint stripper and it worked great
Thanks for your videos!!

[@HaseebElectronics]

yes it is protective layer, it makes insulation
we can use thinner, isopropyl alcohol, to remove this layer or there are are some sprays are available from aerosol to remove arylic and silicon coatings

[@gayanwijethilaka9135]

after the plastic coating if another repair comes how can we clean it?

[@HaseebElectronics]

just apply thinner, isopropyl alcohol, spirit,

[@MACYNET323]

This is good for naked copper traces to prevent oxidation?

[@HaseebElectronics]

UV cureable masking ink is better
but this conformal coatiing is also a good protective method for prevention from oxides

[@raczyk]

Where do you buy this stuff? Can't seem to find it here in Canada where I live, Kontakt Chemie Plastik 70.

[@HaseebElectronics]

good morning
i purchase these items from local market here in Jordan, these sellers have superb quality products
you can find online. many online vendors are selling this product

[@Hhtfvhrcbgrejkkjhffvbhb]

64 pin smd ic on pcb, this pcb heavy coating lears, now this ic pinon this coating how removed???
Any spary available this coating removed??

[@James-wd9ib]

First, you have to cover the contacts with a little tape. . . .

[@HaseebElectronics]

yes dear you are right
