let's continue with the introduction of the roles of other layers in PCB: 1. Solder Mask Layer 2. Silk Screen Layer 3. Other Layers

It is well known that PCB is an indispensable part of electronic products, composed of multiple layers, each with its specific function. Today we will explore the different functions of each layer.

Finally let’s learn about the function 5 and 6 about capacitor. Timing Tuning

The Six Functions of Capacitor in PCB (Part 2) Bypassing Energy Storage

Capacitors are a common electronic component that plays an important role in circuit boards. Capacitors serve various functions in circuit boards such as filtering, coupling, bypassing, energy storage, timing, and tuning. Capacitors can filter out noise, transmit signals, isolate DC, store electrical energy, control timing, and adjust frequencies to ensure the performance and reliability of the circuit.

The next two types of lamination structures to be presented are the "N+N" structure and the any-layer interconnect structure.

Let's continue to introduce the next structure: “2-N-2” structure.

Today, let's start with the simplest stack-up design, the "1-N-1" structure.

We all know that in the modern electronics manufacturing field, HDI technology has become a key factor in driving electronic products towards miniaturization and higher performance. The core of HDI technology lies in its unique stack-up design, which not only greatly enhances the space utilization of the circuit board but also significantly strengthens electrical performance and signal integrity.

Next, we continue to study the electroplating capabilities of high aspect ratio HDI boards.

As we all know that, With the rapid development of communication and electronic products, the design of printed circuit boards as carrier substrates is also moving towards higher levels and higher density. High multi-layer backplanes or motherboards with more layers, thicker board thickness, smaller hole diameters, and denser wiring will have greater demand in the context of the continuous development of information technology, which will inevitably bring greater challenges to the PCB-related processing processes.

Mobile PCB are one of the most critical components inside a mobile phone, responsible for power and signal transmission as well as the connection and communication between different modules.
