ショウワ Company Profile

In small electronic devices such as mobile phones and laptops, issues arise due to high-density mounting of electronic components and the use of low-voltage ICs for power-saving purposes, leading to unwanted radiation in the high-frequency range and complex electromagnetic interference between components and circuits. The "Noise Suppression Sheet" is designed to mitigate the effects of electromagnetic waves by regularly arranging soft magnetic materials with high permeability within a resin matrix, while also electrically isolating the powder particles from each other. By applying this sheet near the source of noise, inductive coupling is suppressed, high-frequency noise is attenuated, and unwanted radiation can be effectively suppressed without secondary effects such as secondary radiation or signal degradation. Additionally, it is flexible and can be applied to bent areas. More detailed information is available from related products and catalogs.

"Graphite" is a lightweight material that has very high thermal conductivity in the plane direction. Our company, based on extensive processing experience, is able to solve various challenges related to graphite sheets and provide products tailored to customer needs. For powder/layer delamination measures, we can propose suitable double-sided tape and auxiliary materials based on our numerous processing achievements. In addition to roll-to-roll processing, we also have production equipment that can continuously handle the processing of graphite sheets into the necessary shapes, transport them in sheet form, and laminate them, in order to minimize material loss. [Functions of Graphite (Heat Dissipation Sheet)] - Thermal conductivity in the plane direction (about 4 times that of copper, about 7 times that of aluminum) - Lightweight - Flexibility - Low water absorption - Electromagnetic wave shielding effect More detailed information is available in related products and catalogs.
