With the promotion of artificial intelligence and 5G, the development of drones in China has been on a fast track of rapid growth, and civilian drones have maintained a growth rate of over 50% for three consecutive years. Based on the continuous outbreak of downstream application market demand, it has brought great imagination to the [...]
A simple understanding of PCB and its composition In the electronics industry, there is a key component called PCB (printed circuit board). This is a very basic component, which makes it difficult for many people to explain what a PCB is. This article will provide a detailed explanation of the composition of PCBs and some [...]
The open circuit and short circuit of PCB circuit boards are almost daily problems encountered by PCB printed circuit board manufacturers, which have been troubling production and quality management personnel. We have accumulated some experience in improving the open and short circuits of printed circuit boards. Now we have written a summary of the discussion [...]
The copper foil used in the PCB industry is more complex than actually imagined. Copper is not only an excellent good conductor, but also an excellent thermal conductor, making it an ideal material for the vast majority of PCB application conductors. Copper foil has many other characteristics, and understanding these characteristics is crucial for engineers. [...]
How to consider impedance control and stack design during PCB design process? (The following text has been reprinted from the internet. We welcome everyone to supplement and correct it.) With the continuous growth of PCB signal switching speed, today's PCB design manufacturers need to understand and control the impedance of PCB traces. Correspondingly to the [...]
(The following text has been reprinted from the internet. We welcome everyone to supplement and correct it.) Characteristic impedance: also known as "characteristic impedance", it is not a DC resistor and belongs to the concept of long line transmission. In the high frequency range, during signal transmission, a transient current will be generated between the [...]
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 [...]
