SMT PCB What is SMT? Surface Mount Technology (SMT) is a new generation of electronic assembly technology. It compresses traditional electronic components into devices with a volume of only a few tens of times smaller, thus achieving high density, high reliability, miniaturization, low cost, and automated production of electronic product assembly. This miniaturized component is…
blind buried vias 1. What are blind and buried vias? As the design of portable products is developing towards miniaturization and high density, the design difficulty of PCB is also increasing, and higher requirements are put forward for the production process of PCB. In most of the current portable products, BGA packages with a pitch…
1. The names of circuit boards are: Circuit board, PCB board, aluminum substrate, high-frequency board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. We divide the circuit…
What is a functional block in a circuit board? I believe many people know about circuit boards, so what are its functions? We should start by learning which functional blocks the circuit board is divided into. When we know the functional block circuits of each part of the circuit board, and then learn the structure and working principle…
PCB design wiring Wiring, also known as Layout, is one of the most basic and important work skills for PCB design engineers. The quality of routing will directly affect the performance of the entire system. Most high-speed design theories must ultimately be implemented and verified through Layout. It can be seen that routing is crucial…
What is a substrate? What is a substrate? A substrate is the basic material for manufacturing PCBs. When we usually say what a substrate is, we mean a copper-clad laminate. This article introduces what a substrate is, the development history of substrates, and the classification method and implementation standards of substrates. 1. What is a…
1. Understanding copper foil in PCBs Copper foil used in the PCB industry is more complex than you might think. Copper is both an excellent conductor and an excellent thermal conductor, making it an ideal conductor for most PCB applications.
