A few days ago, I wrote an article summarizing the performance window for mid-year reports in the PCB sector. Here, I will supplement some additional stocks. 1. High-end Substrates and Copper Foil 1. Jin’an Guoji: Domestic replacement of high-frequency and high-speed copper-clad laminates, certified by NVIDIA AI servers. 2. Shengyi Technology: Among the top five … Read more
What is a printed circuit board? A printed circuit board is a circuit formed by arranging conductive metal lines on an insulating substrate. In simple electronic projects, reconfigurable circuit boards such as breadboards or universal boards are often used, while printed circuit boards are fixed substrates that have these circuits pre-manufactured. The greatest advantage of … Read more
Research Guide on Carrier-Supported Copper Foil, Coreless Support, and PCB Manufacturing Methods 1. Overview and Core Concepts This research guide aims to provide an in-depth understanding of carrier-supported copper foil and its applications in coreless support and printed circuit board (PCB) manufacturing. The focus is on a novel design of carrier-supported copper foil that addresses … Read more
This article will explain the composition of PCBs in detail, as well as some commonly used terms in the PCB field, a brief assembly method, and an overview of the PCB design process. 01Birth of PCBBefore the advent of PCBs, circuits were composed of point-to-point wiring, which had low reliability. As circuits aged, wire breakage … Read more
The PCB industry chain is structured as follows: Upstream Raw Materials — Midstream Substrates — Downstream PCB Applications Upstream Raw Materials Upstream raw materials include copper foil, resin, fiberglass cloth, wood pulp, ink, and copper balls, among which copper foil, resin, and fiberglass cloth are the three main raw materials. Copper foil is the primary … Read more
Click the above“Mechanical and Electronic Engineering Technology” to follow us PCB, or Printed Circuit Board, is the “heart” of electronic products, and nearly all electronic devices rely on it. The phone in your hand, your computer, and even the television and refrigerator at home all hide the presence of PCBs. In 2024, the PCB industry … Read more
Copper foil is the main material used in PCBs, primarily for transmitting current and signals. The copper foil on a PCB can also serve as a reference plane to control the impedance of transmission lines or as a shielding layer to suppress electromagnetic interference. During the PCB manufacturing process, characteristics such as the peel strength … Read more
The main conductor material used in PCBs is copper foil, which is used for transmitting signals and currents. At the same time, the copper foil on the PCB can also serve as a reference plane to control the impedance of transmission lines or as a shielding layer to suppress electromagnetic interference (EMI). Additionally, during the … Read more
