Analysis on Why 1mm Trace Width Is Required for 1A Current in PCB Layout

2026-04-29

for high-current applications, the appropriate trace width must be selected by comprehensively considering factors such as current load, cross-sectional area, heat dissipation requirements, and space constraints. Optimal design decisions require basic electronic and electrical knowledge combined with practical experience.

How to Implement ESD-Resistant Design for PCBs

2026-04-29

ESD-resistant design of PCBs can be realized through layer stacking, proper component layout, routing and assembly. In the design phase, most design modifications can be limited to adding or removing components through prediction. ESD protection can be effectively achieved by adjusting PCB layout and routing.

Why Should Series Termination Resistors Be Placed Close to the Transmitter for Impedance Matching on Transmission Lines

2026-04-28

During impedance matching, a series termination resistor can be placed at the signal source. However, due to space constraints, the resistor may be placed slightly farther away. This raises a common question: if the resistor is placed far from the transmitter or at the receiver, can it still eliminate reflections on the transmission line? The following simulation results verify this.

Key Points of LDO PCB Layout and Routing

2026-04-28

LDO stands for Low Drop-Out, also known as a low-dropout regulator. It is an electronic component mainly used to step down high voltage to a lower voltage and provide stable power supply. An LDO module usually consists of a DC voltage regulator and a current amplifier. Its working principle is to create a stable voltage difference between the input and output to ensure the output voltage stays within a reliable range.

Power Integrity and PDN Design for PCB Routing

2026-04-28

SI (Signal Integrity) focuses on the waveform quality of signals, while PI (Power Integrity) focuses on the waveform quality of power supplies. The research object of PI is PDN (Power Distribution Network), which studies power issues from a more systematic perspective, eliminates or mitigates power noise, meets the load demand for current at different frequencies, and provides clean, stable and reliable power for loads.
