Power splitters and combiners are the most commonly used/common high-frequency devices, and the same applies to couplers such as directional couplers. These devices are used for power splitting, combining, and coupling high-frequency energy from antennas or internal systems, with minimal loss and leakage. The selection of high-frequency PCB boards is a key factor for achieving [...]
1、 The difference between ceramic substrate and PCB board 1. The materials are different. Ceramic substrates are inorganic materials, with the core being aluminum trioxide or aluminum nitride; The ordinary PCB board uses FR4 fiberglass board, which is an organic material. Ordinary pcb boards can be laminated in multiple layers. LTCC is the mainstream of [...]
PCB (Printed Circuit Board) is the most common substrate in electronic components, commonly used in various circuit connections and electronic device manufacturing. However, in practical use, it is important to pay attention to the issues of open and short circuits on the PCB board. The editor of this article will introduce the causes and solutions [...]

There are various circuit boards in modern mobile phones, and the production of these circuit boards can be divided into soft boards and hard boards. So, which type of circuit board is better? 1. Soft board: It is made of polyimide material, with good flexibility, and can realize some bending degrees of freedom that hard [...]
The circuit board is an important component of electronic equipment, and its normal operation requires ensuring the cleanliness and quality of the circuit board. During the use of a circuit board, the accumulation of dust, oil stains, dirt and other substances, as well as the splashing of corrosive liquids, can affect the conductive surface of [...]
One important factor that causes circuit board failures is the unstable working voltage supplied to the circuit board. What situations can cause voltage instability? Personnel engaged in equipment maintenance can develop relevant measures based on the analyzed reasons, in order to avoid or reduce circuit board failures caused by voltage instability. The factors of voltage [...]
