Where is the position of the PCB? Almost all electronic devices have PCBs. They come in shades of green, red, blue, or black. A computer motherboard is a perfect example of a PCB. They exist in everyday appliances such as printers, digital clocks, televisions, microwave ovens, and even some simple items such as light switches.

In a new energy vehicle electronic control laboratory in Shenzhen, engineers are facing a headache inducing problem - when the motor controller PCB board is powered on, an abnormal pulse of 50mV will always flash on the oscilloscope. This seemingly small noise is enough to make the onboard radar misjudge the distance of obstacles. This scene reflects the harsh reality of contemporary electronic design: with signal speeds exceeding 112Gbps and power supply voltages dropping to 0.6V, PCB design has evolved from a simple circuit connection to a precise game of electromagnetic compatibility. This article will reveal how to construct a "silent barrier" for electronic systems within a nanometer level error range through spatial art of layout and wiring.

A pre biased transistor is a transistor that integrates a bias resistor during the manufacturing process. This design is cost-effective, as the integrated components save on the cost of printed circuit boards (PCBs) and reduce the number of items in the bill of materials (BOM). A typical product is the DDTD113ZC-7-F NPN transistor from Dior, packaged in SOT-23-3, as shown in Figure 1. This pre biased transistor includes a 1 kiloohm series current limiting resistor and a 10 kiloohm turn off resistor connected in parallel with the base emitter junction.
