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 …
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 …

What is the Thermoelectric Separation Substrate? The circuit part and the thermal layer part of the substrate are on different circuit layers, and the thermal layer part directly contacts the heat dissipation part of the lamp bead to achieve the best heat dissipation (zero thermal resistance) effect. And the material of the substrate is generally …

There are a lot of parameters to be confirmed when making PCB. It’s easy to understand the parameters such as size, quantity, plate materials, thickness, solder resist color and silk screen color. But there is some parameters that are not so easy to understand, such as copper thickness, minimum line width / line distance, minimum aperture, through-hole …
With the development of electronic products, the technical demand of using FPC soft board to connect to PCB is higher and higher. But how to connect them? Following we will introduce several common connection and welding methods between FPC and PCB in the industry. FPC ( “flexible printed circuit board” or “flexible circuit board”) is …
