Click the blue text to follow us Printed Circuit Boards In the early 20th century, Paul Eisler first proposed the concept of “printed circuits” and developed the world’s first printed circuit board (PCB). As the most widely used substrate in secondary electronic packaging technology, it is a substrate covered with single or multiple layers of … Read more
A PCB (Printed Circuit Board) is a board made of insulating material, designed to create conductive patterns for electrical connections between components. The conductive patterns formed on the insulating substrate are referred to as printed circuits. Thus, the finished board is called a printed circuit board, also known as a printed board or PCB. PCBs … Read more

10-Layer First-Level HDI PCB Manufacturing Process and Technical Points 1. Definition and Features of 10-Layer First-Level HDI Board The 10-Layer First-Level HDI (High-Density Interconnect) board is a type of multi-layer PCB that uses blind hole technology to connect the outer and inner layers, structured as 1+8+1, which means 1 outer layer, 8 inner layers, and … Read more
With the rapid development of the PCB industry, PCBs are gradually moving towards high-precision fine lines, small apertures, and high aspect ratios (6:1-10:1). The copper requirement for holes is 20-25μm, and for boards with DF line spacing ≤4 mil, most PCB manufacturers face plating film issues. Film entrapment can cause direct short circuits, affecting the … Read more

The surge in AI computing power demand drives the need for high-end PCBs, with domestic mainstream manufacturers actively expanding production. 1) Computing power demand: Against the backdrop of sustained high computing power demand from AIGC and others, the global server market is entering a new growth cycle starting in 2024. IDC predicts that from … Read more
With the rapid development of the PCB industry, PCBs are gradually moving towards high-precision fine lines, small apertures, and high aspect ratios (6:1-10:1). The copper requirement for holes is 20-25μm, and for boards with a D/F line spacing of ≤4 mil, most PCB manufacturers face plating adhesion issues. Adhesion can cause direct short circuits, affecting … Read more
Under the “dual carbon” strategic goals, the PCB (Printed Circuit Board) manufacturing industry, as a cornerstone of the electronic information industry, is facing severe energy consumption challenges, and the green transformation of PCB manufacturing is urgent. Industry data shows that the electroplating process, as a core energy-consuming segment, accounts for about 30%-40% of total production … Read more
