High Frequency and Low Loss

Compared to previous resin materials, Multi-layer LCP product has a smaller relative dielectric constant and dielectric loss tangent, and it does not use adhesive to bond the layers in the multilayer substrate manufacturing process.
This makes it possible to achieve a substrate and components that have low loss in the high frequency range. Low loss in the high frequency range indicates superior characteristics for recent applications to high-speed digital transmission.

Comparison of transmission line insertion loss

This graph compares the loss of a Multi-layer LCP product transmission line with an FPC transmission line.
As you can see, Multi-layer LCP product is able to achieve low-loss products to contribute to low power consumption and improve communication performance in customer products. It can also form more detailed electrode patterns compared to previous resin substrates. In addition to reducing the thickness variation by not using adhesive between the layers, the formation of minute electrode patterns enables highly precise impedance control, which is important in the high frequency range and in high-speed digital transmission.

Maintains Complex 2D and 3D Shapes

Multi-layer LCP product is cut out using laser cutting, which makes it possible to bend it in three dimensions and hold that shape to achieve complex 2D and 3D shape designs.

Process support for complex 2D shapes

In the Multi-layer LCP product process, a laser cutter is used to cut out each individual product. Therefore, we can easily handle requests for various complex 2D shapes.
Because no molds are used, we can respond to design changes with short deadlines and at a low cost.

Support for complex 2D shapes

3D shape retention is possible

Bending can be applied to 3D shapes according to customer needs thanks to the flexible, high-strength characteristics of the Multi-layer LCP product material.
Multi-layer LCP product that has not been bent is perfectly flat, but the necessary regions can be bent , much as origami paper is folded, according to customer requests.

It was difficult for the previous FPCs to maintain their shape due to spring back. However, because Multi-layer LCP product can maintain shapes, it is easy for customers to embed during the product assembly process and helps to reduce man-hours.

Bend radius : 2.5t to 3t
Enables small-radius bending.

High-density and Thin Multilayer Substrate

Multi-layer LCP product uses a single press for its multilayer lamination technology, which achieves a high-density and thin multilayer substrate.

Multi-layer LCP product cross-sectional structure example and characteristics

The following three characteristics contribute to the high density.

More detailed patterns can be formed due to etching, compared to previous resin substrates.
Blind, buried, and other via holes can be freely formed.
Cavities can be easily formed.

The following four characteristics contribute to the thin profile.

Thin sheets with a highly precise thickness can be used.
Sheets with different thicknesses can be combined into multilayers.
An odd number of layers can be easily multilayered with batch lamination, as opposed to the previous build-up substrate method.
Adhesive is not required between layers.

Fusing all of these characteristics achieves a high-density, thin multilayer substrate that helps increase the degree of freedom that customers have in designing the interior of products and that saves space.

Humidity-resistant

Compared to previous resin substrates (glass epoxy substrates, FR-4 substrates, FPC, etc.), Multi-layer LCP product uses a resin material with a low ratio of water and moisture absorption. In addition, because adhesive is not required to bond the layers, high reliability products with high water and perspiration resistance can be achieved.

Conventional FPC Product

Multi-layer LCP product

These graphs show the change in the resonance frequency before and after the high-temperature and high-humidity test conducted on both an antenna made with a Multi-layer LCP product and a conventional antenna made with FPC.
We can confirm from the results that the characteristics of Multi-layer LCP product are much more stable than conventional FPC products. Such characteristics are one of the important parameters for products with mechanisms that resonate like antennas.
