Printed circuit board material is composed of fiberglass/plastic substrate, solder mask, copper and named ink. Plastic substrate/fiberglass Manufacturers can use flexible or rigid surfaces when fabricating PCBs. These two surfaces completely depend on the PCB design required for the project. Importantly, tough surfaces require polyamide fiberglass or FR4. At the same time, the flexible surface …
A multi-layer PCB is a printed circuit board with more than 2 layers. A double-sided PCB has two conductive layers on the top and bottom of the PCB substrate. A multi-layer PCB must have at least 3 conductive layers of conductive material or copper layers. All layers are interconnected with copper vias. It can be 4 …

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 …
