A brief discussion on circuit board design criteria for ensuring signal integrity

Signal integrity circuit board design criteria include SI problems, pre-design preparation, cascade, crosstalk and impedance control, high-speed nodes, technology selection, pre-wiring stage, post-wiring SI simulation, post-manufacturing stage, model sele

Cause analysis of wrinkle and bubble of welding ink on circuit board

The bubbling of the circuit board is actually the problem of poor binding force of the board, that is, the surface quality of the board, which includes the cleanliness of the board and the surface microscopic roughness (or surface energy).

New energy intelligent vehicle pull PCB circuit board demand

the trend of automobile electrification and electronization is more and more obvious. As the infrastructure of electronic products, PCB manufacturing is becoming increasingly important in the automotive supply chain

New energy intelligent vehicle pull PCB circuit board demand

Special attention needs to be paid to the selection of materials to ensure stability in terms of temperature, humidity and bias in addition to electrical properties. This will lead to future restrictions on material selection and design rules.

The influence of circuit board hole on signal transmission

Perforation is one of the important components of multilayer PCB board, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB board. Simply put, every hole in the PCB can be called a pass hole.

PCB circuit board proofing a few tips of common sense
