Conformal paint is a kind of protective
paint with a special formula, and UV conformal paint is an important type of
conformal paint. With its unique curing method and excellent performance, it is
widely used in electronic device circuit boards and related components. As UV
conformal paint receives more attention, many people begin to want to
understand its advantages and disadvantages.
Nufil is an innovative enterprise that has
been deeply involved in the field of electronic adhesives for more than ten
years, and has a good reputation in the industry with its self-developed
conformal paint products and adhesive technology solutions. Based on years of
research and understanding of UV conformal coatings, Nu Fei leads everyone to
deeply discuss the advantages and disadvantages of UV conformal coatings,
helping everyone to understand this material more comprehensively. UV conformal
coatings have the advantages of fast curing, high adhesion, good protective
performance, good environmental protection, high transparency and easy
operation, and have a wide range of application prospects in the field of
electronic equipment protection. Among them, rapid curing can greatly improve
production efficiency; High adhesion provides reliable protection for different
materials; Protective properties include waterproof and moisture-proof,
chemical corrosion resistance and wear resistance. environmental protection
meets modern needs; High transparency is suitable for equipment with high
appearance requirements; Easy to operate and suitable for a wide range of
production methods. However, it also has disadvantages such as difficulty in
curing where it is not illuminated, high cost, limited curing depth (special
cases), and possible whitening of the coating film under certain conditions.
Advantages of UV conformal paint:
<!--[if !supportLists]-->1.<!--[endif]-->Fast Curing
One of the biggest advantages of UV conformal coatings is their ability to cure
quickly under UV light, typically in just a few seconds to tens of seconds.
Compared with traditional conformal paints, which take a longer time to dry and
cure, this greatly improves production efficiency and can meet the needs of
rapid production in modern electronics manufacturing. The line does not spend a
lot of time waiting for the coating to dry, and it can operate continuously,
which is especially evident in large-scale production.
<!--[if !supportLists]-->2.<!--[endif]-->High
adhesion UV conformal paint has high adhesion to all kinds of circuit board
substrates, plastics, glass, metals and other materials. This indicates that it
can adhere firmly to surfaces of different materials, providing reliable
protection for electronic devices. Whether inside complex electronic devices or
on components made of various materials, UV conformal paint can play a good
protective role and is not easy to peel off or peel off.
<!--[if !supportLists]-->3.<!--[endif]-->Good
protection Waterproof and moisture-proof: UV conformal paint has excellent
waterproof performance, which can effectively prevent moisture from penetrating
into electronic devices, avoiding short circuits, corrosion and other problems
caused by moisture. For electronic devices used in humid environments (e.g.
bathrooms, kitchens) or outdoor electronic devices, the waterproof properties
of UV conformal coatings provide reliable protection for equipment. Chemical
resistance: It can resist the attack of chemicals such as acids, alkalis, and
solvents, and can protect electronic devices in harsh chemical environments. In
the fields of chemical industry, battery production, etc., electronic devices
are often exposed to various chemicals, and the chemical resistance of UV
conformal coatings ensures the normal operation of equipment. Wear resistance:
The cured UV conformal paint has high hardness and wear resistance, and can
withstand a certain degree of friction and scratches, maintaining the surface
finish and aesthetics of electronic devices. In daily use, electronic equipment
will inevitably be subjected to some slight friction and collision, and the
wear resistance of UV conformal paint can effectively protect the surface of
the equipment from damage.
<!--[if !supportLists]-->4.<!--[endif]-->Good
environmental protection UV conformal paint is a solvent-free or low-solvent
coating, which will not emit volatile organic compounds (VOCs) during the
construction process and cause less pollution to the environment. With the
continuous improvement of environmental awareness, more and more enterprises
and consumers have begun to pay attention to the environmental performance of
products, and this characteristic of UV conformal paint makes it highly
competitive in the market.
<!--[if !supportLists]-->5.<!--[endif]-->High
transparency UV conformal paint has good transparency, and after coating, it
will not affect the appearance and color of electronic devices, and can
maintain the original appearance of the coated object. This is important for
electronic devices such as smartphones and tablets that require a high degree
of appearance. At the same time, high transparency also facilitates the
observation and detection of circuits and components inside electronic devices.
<!--[if !supportLists]-->6.<!--[endif]-->Easy to
operate UV conformal paint can be applied through spraying, brushing, dipping
and other methods, making it easy and convenient to operate, suitable for
different types and scales of production. Moreover, it can adopt the equipment
spraying process, which can achieve precise control and improve the automation
level of the production process.
Disadvantages of UV conformal paint:
<!--[if !supportLists]-->1.<!--[endif]-->Difficult to
cure where the light does not reach Some shadowed areas and dead zones on the
board may not reach UV light, which can lead to uneven curing of the coating as
a whole. However, Nufil has independently developed a UV moisture double-curing
conformal paint CA6001 that can be UV cured and moisture cured, which can solve
the problem of UV curing well.
<!--[if !supportLists]-->2.<!--[endif]-->Higher Cost
Compared with traditional conformal paints, the price of UV conformal paints is
relatively high. This is mainly because the formulation of UV conformal paints
uses more expensive raw materials, which increases the production cost.
Moreover, the use of UV conformal paint requires suitable ultraviolet
irradiation equipment, which is more expensive than other types of conformal
paint.
Conclusion In fact, in addition to the
above two disadvantages, UV conformal paint may also have the disadvantage of
limited curing depth, and for some thicker coatings or electronic devices with
complex structures, the inside of the coating may not be completely cured.
However, the coating of the circuit board is usually not too thick, so this
disadvantage is basically negligible. Of course, under certain conditions (such
as unsuitable temperature and excessive moisture), the coating film of UV
conformal paint may appear whitening like conventional conformal paint, and
paying attention to the temperature and humidity of the sizing environment can
also avoid such shortcomings.
When you have a comprehensive understanding
of UV conformal paint, you can choose the appropriate conformal paint product
and construction process according to the needs and conditions during
application, which will help UV conformal paint play a better protective
effect. However, the UV moisture double-curing conformal paint CA6001 developed
by Nufil can solve some curing problems, and in most cases, such as when the
circuit board coating is not thick, the disadvantages of limited curing depth
can be ignored, and pay attention to the sizing environment to avoid the
whitening problem of the coating film. In practical applications, a
comprehensive understanding of its advantages and disadvantages can help choose
the right product and construction process according to the needs and
conditions, so that the UV conformal paint can achieve the best protection
effect.
