Factors to consider in PCB stack-up design 1. Hardware cost The number of PCB layers is directly related to the final hardware cost. The more layers, the higher the hardware cost. Hardware PCBs represented by consumer products generally have the highest limit on the number of layers, such as notebook computer products. The number of …
The PCB panel refers to making a piece of small PCB board directly into a whole piece by the manufacturer. Why Do PCB Panels? To meet the needs of production. Some PCB boards are too small to meet the requirements of fixtures, so they need assembly for production. Improve the welding efficiency of the SMT patch. It …
With the development of science and technology, especially in the advancement of the materials of integrated circuits, the computing speed has been significantly improved, which has led to the development of high-density, small-volume, and single-component integrated circuits, which all lead to today’s and future printed circuit boards. The application of high-speed digital circuits, that is, it …
