Let's continue to learn about 4 situations and methods to reduce the tight delay deviation.

In the context of PCB design and manufacturing, the term "tight delay deviation" between positive and negative signals refers to the time difference in the transmission process between the two signals (positive and negative) of a differential signal pair. This deviation can affect the integrity of the signal, especially in high-speed data transmission, as it may lead to data errors or signal distortion.

Let’s continue to learn about the details of differential routing in HDI PCB.

Today, we will delve into the details of differential routing in HDI PCBs. There are a total of nine steps, which we will discuss in three parts.

Let’s continue to the next tip in PCB routing: In the context of PCB manufacturing, maintaining signal integrity is crucial, especially for high-speed signals. One technique to enhance signal integrity is to implement daisy chaining, which involves routing signals in a sequential manner to minimize stub lengths. Stubs, or short extensions of a trace, can act as antennas and increase compliance with EMC (Electromagnetic Compatibility) standards, potentially leading to signal reflection and degradation.

Today let’s continue to the next tip in PCB routing: In the context of PCB manufacturing, minimizing crosstalk between traces is crucial for maintaining signal integrity. Crosstalk levels depend on the length and distance between two traces. In certain areas, trace routing may reach a bottleneck where traces are closer than expected. In such cases, it is necessary to increase the distance between adjacent signals beyond the minimum requirements.

In the context of PCB manufacturing, routing high-speed signals requires special attention due to their sensitivity to the shape and layout of the traces. When bends are necessary in high-speed signal routing, it's best to avoid sharp 90° angles, as these acute corners can cause signal reflection and interference, acting much like antennas and thus affecting signal integrity.

Let’s see a new immersion gold PCB which will be send out today, one of our customers in Europe ordered batch of it.

On November 13, 2024, the 2024 ASEAN-CHINA GBA Economic Cooperation Forum was grandly inaugurated in the Greater Bay Area of Shenzhen, and Sanxis Tech Co., Ltd. was also honored to be invited to participate in this forum.

Here is the next tip in PCB routing: In the context of PCB manufacturing, vias are crucial structures for connecting signals and power between different layers. However, the gaps created by vias in the power and ground planes can lead to uneven current density, resulting in hotspots. Hotspots refer to areas where the current density is abnormally high, which can cause localized overheating and affect the reliability and performance of the circuit.
