1.Familiarity with factory manufacturing processes In this era of fabless IC companies, it is not surprising that many engineers are not aware of the production steps and chemical treatment processes for PCBs manufactured based on their design files. However, this lack of practical knowledge often leads novice engineers to make unnecessary and more complex design…
1 Layer distribution （1） Double-layer board, the top layer is the signal layer, the bottom layer is the ground plane. （2） Four-layer board, the top layer is the signal layer, the second layer is the ground plane, and the third layer is the power supply and control line. In special cases (such as RF signal…
1.Definition of signal integrity: Definition: Signal integrity (SI) refers to the quality of the signal on the signal line. Poor signal integrity is not caused by a single factor, but by multiple factors in board-level design. When the signal in the circuit can reach the receiving end with the required timing, duration and voltage amplitude,…
blind buried vias 1. What are blind and buried vias? As the design of portable products is developing towards miniaturization and high density, the design difficulty of PCB is also increasing, and higher requirements are put forward for the production process of PCB. In most of the current portable products, BGA packages with a pitch…
What is a rigid PCB PCBs are further divided into rigid PCBs and flexible PCBs, and both rigid and flexible printed circuit boards (PCBs) are used to connect electronic components in a variety of consumer and non-consumer devices. As the name implies, rigid PCBs are circuit boards built on a rigid base layer that cannot bend, while…
