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 [...]
In the modern electronic product manufacturing industry, circuit boards are a crucial component. Different types of circuit boards play different roles in different applications. Among them, there are significant differences in design and use between high-frequency circuit boards and ordinary circuit boards. This article will provide a detailed introduction to the differences between the two, [...]
With the continuous progress of technology, electronic circuit boards, as the core component of electronic products, are also constantly developing and innovating. From single-sided circuit boards, double-sided circuit boards to multi-layer circuit boards, from rigid circuit boards to flexible circuit boards, and rigid flexible combination circuit boards, the types and functions of electronic circuit boards [...]

Discussion on Key Materials of High Frequency Microwave RF PCB Circuit Board The circuit materials of printed circuit boards (PCBs) are key building blocks for radio frequency (RF)/microwave circuits - essentially the starting point of these circuits. PCB materials come in many different forms, and the selection of materials largely depends on the requirements of [...]
Many customers and design engineers often ask what this means when placing orders on the system, and which option should I choose for my file, regarding the distinction between VIA and PAD in terms of "through hole cover oil" and "through hole opening window"? The following is an explanation of this issue: I often encounter [...]
Exploring the performance of high-frequency millimeter wave frequencies in different high-frequency materials The millimeter wave frequency band is gradually being more applied due to its greater bandwidth advantage. Circuit developers for many emerging applications such as 5G wireless networks and ADAS cars are facing the challenge of designing and producing practical and feasible 30 to [...]
Why do people often lift a 50 Ω impedance when designing a PCB In PCB design, impedance usually refers to the characteristic impedance of the transmission line, which is the characteristic impedance when electromagnetic waves are transmitted in the wire, and is related to the geometric shape of the wire, the dielectric material, the surrounding [...]
Implementation of "phase shifting" Due to the direct correlation between the "phase" of each signal and the emission direction and stacking strength of the signal, the "phase shifting" function is a very important functional module in phased array systems. In modern phased array systems, the phase shifting function is usually achieved by a phase shifter [...]
Interconnection of antennas and RF chips At present, domestic and foreign chip manufacturers have launched mass-produced 24GHz RF chips into the market. In the zero intermediate frequency radar architecture, the pins of the RF chips are directly connected to the microstrip transceiver antenna ports. When using a hybrid form of antenna board (high-frequency board)+several layers [...]
