Posted on September 19, 2025 by G

Build up Multilayer PCB, BUM refers to the application of insulating dielectric on the insulating substrate, or the traditional double-panel or multi-layer board, and then electroless copper plating and electroplating copper to form wires and connecting holes. A multilayer printed board requiring a number of layers.

Introduction to HDI and circuit boards

Posted on January 13, 2026 by G

Since the printed circuit board is not a general end product, the definition of the name is slightly confusing. For example, the motherboard for the personal computer is called the motherboard and cannot be directly called the circuit board. Although there is a circuit board in the motherboard, It's not the same, so when you evaluate the industry, you can't say the same thing. For example, because there are integrated circuit parts on the board, the news media called him an IC board, but in fact he is not equivalent to a printed circuit board.

Summary of Multilayer Board (BUM-PCB)

Posted on September 19, 2025 by G

As early as the 1970s, there was already a literature report on BUM technology, but it was not until the early 1990s that the Japanese company (Yasu) developed a coating of photosensitive resin on the core board to form conductive micropores by photo-induced method. Even after the new method of manufacturing a high-density circuit board by the new method of addition, the high-density circuit board was successfully used in a Thinkpad type notebook computer, and the new technology was first published in 1991. It is called Surface Laminar Circuit, SLC (Surface Laminated Circuit Board). Since this technology has created an unprecedented high-density Interconnect, HDI (High-density Interconnect) new ideas, Japanese electronics manufacturers have developed and unveiled The BUM era in the history of PCB development.

How to deal with the interference of circuit board parasitic components on circuit performance

Posted on October 14, 2025 by G

The main parasitic components generated by board layout are resistors, capacitors, and inductors. When switching from a circuit diagram to an actual board, all parasitic components have a chance to interfere with circuit performance. When a system mixes digital and analog components, careful routing is key to the success of the board. In particular, digital traces that are often close to high-impedance analog traces will cause severe coupling noise, which can only be avoided by keeping the two traces at a distance. This article quantifies the toughest board parasitic components, board capacitors, and lists the performance examples that can be clearly seen on the board.
