What is Liquid Crystal Polymer?
Liquid crystalline polymers (LCPs) are a special
sort of thermoplastics that exhibit buildings
between very purchased strong crystalline
products and amorphous disordered fluids over a
well- defined temperature level range china pcb
assembly. LCP is a high-performance thermoplastic
product with excellent thermomechanical habits.
It can be thermoformed (also as an intricate
multilayer flex with embedded thin film traces)
to any type of preferred shape. At area
temperature, slim LCP movies and also fibers
display mechanical residential or commercial
properties close to steel. The functional
temperature for LCP circuits can get to 190 C.
Multiple, conventional SMT reflow, as well as
soldering operations, are possible. LCPs also
supply low dampness absorption and also chemical
security. It belongs to the polymer products
with the most affordable permeability for gases
and also water pcb electronics. LCP can be
adhered to itself, permitting multilayer building
and constructions with an identical framework.
As a result of these properties, they can be
utilized for real estate and also encapsulation.
LCP adheres well to most products if the
breeding material is sufficiently rough.
LCP PCB Can Attain Higher Miniaturization Take
smartphones as an example. With the increase of
complete screens, item morphology changes, even
more elements included, bigger batteries, and so
on, these are all reasons for further
compression of the internal room of mobile phones
circuit card assembly. The space where antennas
can be made use of for layout is obtaining
smaller as well as smaller, and also
miniaturization methods such as antenna
selections are emerging one after another. There
are three main facets to the compression of the
internal room of the cellphone (1) Full-screen
layout, although the length and also size of the
mobile phone come to be larger, the density
remains to decrease. (2) More and more useful
parts incorporated by smart devices, such as
sensors as well as cams, further capture room.
(3) The power usage of bigger display dimensions

practical elements has enhanced dramatically,
while the battery thickness normally just
increases by 10 annually. The raised power need
makes the battery quantity larger as well as
bigger. To transform the "home" of the antenna
inside the mobile phone, along with maximizing
the antenna efficiency and also embracing the
variety structure, more efforts require to be
made from the crucial kind of the antenna. The
LCP soft board has a much better adaptability and
can further improve room usage compared with the
PI soft board. Usage resistance adjustment is
higher than 10 to court. Under the same
experimental problems, LCP soft board can endure
much more flexing times as well as a smaller
flexing span than a typical PI soft board, so LCP
soft board has better Versatile performance and
product integrity. Furthermore, the excellent
versatility permits the LCP soft board to easily
create the shape, to adapt to the little room
inside the cellphone. Take the flexible board
that covers the battery as an example. The LCP
adaptable board can fit the battery well, while
the PI versatile board cannot near the battery
surface under the influence of the rebound
effect, which creates the inner structure of the
entire machine to be loose and also inefficient.
A particular quantity of room. The LCP soft board
can lower the density of the antenna
transmission line by 65, which can even boost
room use. The typical design uses an antenna
transmission line, which is what we call a coax,
to transfer the signal from the antenna to the
motherboard, while multi-mode as well as
multi-frequency call for numerous antenna
transmission lines to be placed in a tiny room.
The LCP soft board has the same superb
transmission loss as the antenna transmission
line. It can lug several transmission lines in a
three-layer structure of only 0.2 mm and also
lead out numerous super high frequency lines.
This suggests that the use of the LCP soft board
can replace the thick Antenna transmission line
as well as the coaxial port to reduce the density.
