What is HumiSeal coating?
HumiSeal Products are conformal coatings which are designed to prevent corrosion and degradation of electronic assemblies in circuit boards and automotive electronics control components.
How do I get rid of HumiSeal?
HumiSeal UV conformal coatings can be removed using select strippers after UV cure, before the secondary moisture mechanism has completed. See Table 1 for the appropriate stripper selection. HumiSeal UV40, UV50LV and UV40-250 can only be removed using Stripper 1100 once the coating has been UV and moisture cured.
Is conformal coating toxic?
If the Conformal Coating uses toluene and xylene as thinner, this chemical is harmful to the human body. If it is used, it is harmful to lipids and alcohols. small. Xylene is moderately toxic and has a stimulating effect on the eye and upper respiratory tract.
Does conformal coating affect performance?
Conformal coating inevitably affects capacitance, but it will also affect resistive leakage if you don’t apply it carefully.
What is conformal coating material?
Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board’s components. Typically applied at 25-250 μm(micrometers) thickness, it is applied to electronic circuitry to protect against moisture, dust, chemicals, and temperature extremes.
How do you treat conformal coating?
UV (Ultraviolet) Cure: Conformal coatings that cure with UV light. The light wavelength and energy influence the rate and ability of the coating to cure. Typically, UV cure coatings have secondary cure mechanisms to ensure any coating not cured by the UV light will eventually cure.
What is type AR conformal coating?
Chemtronics. Konform AR is ideal for providing insulation against high-voltage arcing and corona shorts. This extremely effective acrylic conformal coating provides a hard, durable protective barrier against humidity, salt, corrosive vapors and fungus for printed circuit board and electronic assemblies.
What is the purpose of conformal coat?
A conformal coating is a thin polymeric film applied to a printed circuit board (PCB) in order to protect the board and its components from the environment and corrosion.
What is conformal coat used for?
Conformal coating is a protective coating or polymer film 25-75µm thick (50µm typical) that ‘conforms’ to the circuit board topology. Its purpose is to protect electronic circuits from harsh environments that may contain high humidity, a range of airborne contaminants and varying temperatures.
How do I remove HumiSeal 1B31?
According to the Humiseal product spec sheet, “HumiSeal 1B31 is a fast air drying, single component, acrylic coating that provides excellent moisture and environmental protection for printed circuit assemblies.” Acrylics are best removed with the Lead-Free Flux Remover – PowerClean™ (#MCC-PW210A) or the Heavy Duty Flux …
How do you remove conformal coating?
1) Heat the entire board to 150°C [300°F] and strip the coating once it softens (while still hot). 2) Use a hot-air de-soldering tool or a solder gun to remove spot areas of the coating. Apply the heat source to the treated area and remove the coating as it softens.
What is humiseal® 1b31?
HumiSeal® 1B31 is a fast drying, single component, acrylic conformal coating that provides excellent moisture and environmental protection for printed circuit assemblies. HumiSeal® 1B31 demonstrates excellent flexibility, fluoresces under UV light for ease of inspection and is easily repaired. HumiSeal® 1B31 coating is MIL-I-46058C
What is a 1b31 sealant?
HumiSeal® 1B31 Acrylic Conformal Coating is a one component, fast curing acrylic coating that is used for circuit assemblies and can be easily repaired. It offers excellent flexibility, moisture and environmental protection, and fluoresces under UV light to aid inspection.
Is humiseal safe to use?
It is environmentally safe and fluoresces under UV light to aid inspection. 300 g Aerosol. HumiSeal® 1B31 Acrylic Conformal Coating is a one component, fast curing acrylic coating that is used for circuit assemblies and dispensed from an aerosol can.
How do you check the viscosity of humiseal 1b31?
Viscosity in the dip tank should be checked regularly using a simple measuring device, such as a Zahn or Ford viscosity cup. HumiSeal 1B31 can be sprayed using conventional spraying equipment. Spraying should be done in an environment with adequate ventilation so that vapor and mist are carried away from the operator.
