Nowadays PCB design time is getting shorter
Therefore, the relationship between the hole and the pin inductive reactance must be considered and the priority of the pass hole specification must be set.

Interference analysis and countermeasure in high frequency PCB design
In PCB, there are only two kinds of transmission lines: strip line and microwave line. The biggest problem of transmission line is reflection, which will cause many problems.
Multi-power layer design
In circuit board design, the thickness, through hole process and the number of layers of circuit board are not the key to solve the problem. Good layered stacking is the key to ensure the bypass and decoupling of the power busbar, to minimize the transien
How to solve signal reflection in high speed PCB board design
In a high speed PCB, wiring is more than just connecting two points. As a qualified engineer, wiring is a hybrid knowledge carrier including resistance, capacitance and inductance.
How to solve EMI problem in multi-layer PCB design
Starting from the most basic PCB board, this paper discusses the function and design skills of PCB stacking in controlling EMI radiation.
High reliability PCB's 14 important characteristics
All of these problems can cause the solder shield to detach from the circuit board and eventually lead to corrosion of the copper circuit.
Why PCB designs generally control 50 ohm impedance?
In terms of PCB design, 50 ohm is also selected after comprehensive consideration. In terms of PCB wiring performance, generally low impedance is better.
The PCB routing density is increasing, so the PCB routing design is particularly important.
With the development of large-scale integrated circuit and super-large scale integrated circuit, the multilayer printed board (PCB) will be used more and more.
Design of PCB anti-jamming technology
The circuit working at high frequency should consider the interference between components. The general circuit should make parallel arrangement of components as far as possible to facilitate wiring;
Cooling tips for PCB circuit boards
To evaluate the heat dissipation capacity of PCB, it is necessary to calculate the equivalent thermal conductivity (9EQ) of the insulating substrate for PCB, which is composed of various materials with different thermal conductivity.
Understand the difference and function of PCB welding aid layer and welding resistance layer
In the process of PCB high-speed signal circuit design and wiring, engineers need to shorten the lead between the pins of high-speed circuit devices as much as possible.
Rf/microwave design considerations
The microstrip line consists of a fixed length of metal or wire and the whole or part of the ground plane located directly below it.
