Overview

5G技术的电磁屏蔽可进行选择性涂覆

Prexonics®为封装级别电磁屏蔽提供准确的无遮盖选择性涂覆，是其主要优势。使用含银墨水的选择性涂覆可以为5G应用提供多种优势。银是一种优秀的电导体，可为5G设备中的元件提供强大的电磁屏蔽，有助于减少干扰并确保信号完整性，这对稳健的5G性能至关重要。这一全新技术使顶部和侧壁的厚度宽高比达到1:1，因此顶部只需要1.5-2μm导电薄膜以实现所需的屏蔽性能。Prexonics®是贺利氏印刷电子的独特全套系统解决方案，由特殊的无颗粒银墨水、喷墨打印机和使用喷墨打印的制造工艺组成，以应用完整、选择性或沟槽涂覆。这种方法允许银墨水的有选择性和精确沉积到元件的特定区域，避免过量材料并最小化浪费。通过使用定制的银墨水，可以在150nm至4µm的范围内实现定制的薄金属薄膜。

Selective coating for EMI shielding in 5G technology

Offering accurate selective coating without any masking is the key benefit of the Prexonics® full system solution for EMI shielding on package level. Selective coating with silver ink offers several advantages for 5G applications. Silver is an excellent electrical conductor and can provide strong electromagnetic shielding for components in 5G devices. This helps to reduce interferences and ensure signal integrity, which is essential for robust 5G performance. This new technology is the first to enable a thickness aspect ratio of 1:1 at topside and sidewalls and thus only 1.5-2μm conductive film on topside is needed to achieve the required shielding performance. Prexonics® is a unique full system solution offered by Heraeus Printed Electronics, that consists of a special particle-free silver ink, an inkjet printer, and a manufacturing process that uses inkjet printing to apply full, partial or trench coating. This approach allows selective and precise deposition of the silver ink onto specific areas of the component, avoiding excess material and minimizing waste. By using the specialized silver ink customized thin metallization films are possible in the range of 150nm to 4µm.
