What is the basis of the current of 1mm PCB trace width over 1A?

2026-03-10

When designing a PCB, if there is a large current, it is necessary to design the corresponding line widths for different current values. In the past, the advice given by the master was that the line width of 1mm exceeded the current of 1A, and it can be estimated according to this.

Routing strategy of PCB with high-level stacked structure

2026-03-10

The wiring strategies of high-level PCB are rich and varied, depending on the functions of PCB. This kind of circuit board may involve many different types of signals, from low-speed digital interfaces to multiple high-speed digital interfaces with different signal integrity requirements. This is undoubtedly a challenging task from the perspective of wiring planning and assigning signal layers to each interface.

What is a Mark point? Mark point is a kind of marking point used for machine vision positioning in the process of PCB processing and mounting. It helps the mounter, welding machine and other equipment to accurately identify the position and direction of the circuit board and ensure the assembly accuracy.

Impedance calculation from introduction to mastery

2026-03-09

In the field of PCB design, "impedance" is the key to determine whether the signal can be transmitted stably. Many engineers have ignored impedance matching and encountered problems such as signal reflection and crosstalk, which led to repeated jamming in product debugging. In fact, as long as you master the core logic of impedance calculation, you can easily deal with it from parameter preparation to software operation.

2026-03-06

In the field of PCB (printed circuit board) design, screen printing, as a key element on the surface of the circuit board, plays an important role. It provides engineers, production personnel and subsequent maintenance personnel with important information such as component number, location and installation direction, and is the core element to ensure the readability and convenience of the circuit board.

Technical specification and best practice of aperture design of PCB through-hole components

2026-03-06

The data sheets of most components contain recommended PCB packaging information and specify the aperture suitable for this component. This is the most practical method to select the aperture of PCB. However, some data sheets only provide the physical dimensions and pin diameter tolerances of components. In this case, how should we choose the aperture when we only create component packages based on these physical dimensions?
