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 pcb assembly china. 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 quick turn pcb assembly. 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 pcb assembly service. 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 and more 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 can not 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 superhigh 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.
