PCB board loss increases! What caused it?
The PCB dielectric loss factor increases, the loss becomes larger and larger, the transmission line length is larger, the loss is larger, the copper foil roughness is larger, the loss is larger.

How do you judge the PCB board
How do we judge the quality of PCB board: 1. Distinguish the quality of PCB board by its appearance; 2. From the PCB board itself to judge its quality, 3. How to judge the SMT patch processing quality: 1. A complete, smooth, polished surface; 2. The appro
Basic knowledge of PCB circuit boards
it is at least attached with a conductive graphic, and cloth holes (such as component holes, fastening holes, metallization holes, etc.), used to replace the chassis of the previous device electronic components, and realize the mutual connection between e
Implanted chips have become a reality, ceramic circuit boards
Human body is a very sensitive organism, if disorderly implantation, the human body will reject many things, serious and even life-threatening, which is why ceramic circuit board is said.
PCB circuit board industry laser marking machine solutions
PCB is one of the important components of the electronic industry, the industrial output value accounts for about a quarter of the total output value of electronic components, the largest proportion in each electronic component subdivision industry
PCB circuit board industry laser marking machine solutions
From the development trend of various regions in the world, after large-scale restructuring, migration and technological upgrading, domestic PCB and FPC production and processing enterprises seize the opportunity of transferring electronic products to the
Understand crystal oscillator from PCB circuit board
Crystal oscillator is short for crystal oscillator. In fact, the common term crystal oscillator also includes crystal resonator, because the core is a quartz crystal.
Must PCB circuit board do impedance?
the tin plating of pcb circuit board is the most prone to problems in the production of the whole circuit board, is the key link affecting the impedance. The biggest defect of electroless tin layer is easy to change color (easy oxidation or delixing), poo
PCB board making technology
All the technical requirements mentioned above should be prepared before light painting. Such as mirroring, solder expansion, process line, process frame, line width adjustment, center hole, contour line and other issues should be in
Rapid board making
Rapid PCB fabrication is a technique that allows you to make hardware development as easy as software development. Master it, can get twice the result with half the effort.
Price of circuit board
Depending on the design of the circuit board, the price will be determined by the material of the circuit board, the number of layers of the circuit board, the size of the circuit board, the number of each production, the production process, the minimum l
How to draw the perfect PCB board?
Priority shall be given to the layout of important unit circuits and core components. Routing signal line priority: analog small signal, high-speed signal, clock signal and synchronization signal and other key signals priority wiring.
