This is a very professional question. Choosing a supplier for PCB high-frequency circuit boards (typically referring to circuit boards used for RF, microwave, and millimeter-wave applications). The definition of “good” includes: material stability, process precision, consistency, technical support capability, price, and delivery time. Below, I will outline several dimensions for you. 1. Core Considerations: Clarify … Read more
In chip manufacturing, the “substrate” not only determines the physical foundation of the wafer but also profoundly affects the electrical performance, reliability, yield, and process compatibility of the devices. But have you noticed? The vast majority of CMOS chips use <100> crystal-oriented silicon substrates. Why does almost the entire industry “favor” the <100> orientation? Today, … Read more

Hello, everyone. Last time we introduced the substrate in packaging, and this time we will discuss the processes involved in substrate manufacturing. After processing, the substrate mainly consists of two materials when viewed in cross-section — dielectric and metal. In terms of metal, the majority is copper, while solder joints are used for connections. In … Read more
DOI:10.1039/d3cs00776f 01 Overview Alumina materials are an important component of modern chemical industry. Catalysts supported on alumina with palladium not only exhibit excellent catalytic activity but also allow for flexible control of surface metal and acidic sites, while also possessing good regeneration performance. These characteristics make them widely used in traditional chemical fields. This article … Read more
