 HDI circuit boards are a type of multi-layer printed circuit board (PCB), which is characterized by more electronic components and connections in a limited space. Compared with traditional circuit boards, HDI circuit boards have higher line density and smaller size. This makes it an ideal choice for modern electronic devices such as smartphones, tablets, laptops, etc. With...

According to the rule of thumb, four-layer boards are usually used in high-density and high-frequency situations. Multi-layer PCBs are more than 20DB better than two-layer boards in terms of EMC. Under the condition of a four-layer board, a complete ground plane and a complete power plane can often be used. Under this condition, it is only necessary to connect the...

With the rapid development of electronic technology and the widespread application of wireless communication technology in various fields, high frequency, high speed and high density have gradually become one of the significant development trends of modern electronic products. The high frequency and high speed digitalization of signal transmission force high-frequency PCBs to move towards micro-holes and buried/blind...

With the development of electronic information technology, multi-layer PCBs are used in more and more fields. Traditionally, we define PCBs with more than four layers as “multi-layer PCBs” and PCBs with more than ten layers as “high-layer PCBs”. Whether or not a PCB manufacturer can produce high-layer PCBs is an important indicator of its strength. A PCB manufacturer that...

At present, high-frequency PCB and high-speed PCB design have become the mainstream, and every PCB Layout engineer should be proficient in it. Today, let’s talk about some design experience of hardware experts in high-frequency and high-speed PCB circuits, hoping to help everyone. 1. How to avoid high-frequency interference? The basic idea to avoid high-frequency interference is to minimize the interference...

Unlike standard printed circuit boards, flexible PCB circuit boards use flexible polymers instead of typical FR4 materials. The commonly deployed flexible polymers require a polyimide film substrate or a polyester substrate, which is a strong material that does not soften under heating and remains flexible when thermoset. A large number of thermosetting resins such as PI remain rigid...

When designing a multi-layer PCB, you need to pay attention to a basic situation, that is, how many wiring layers, ground planes, and power planes are needed to achieve the required functions of the circuit. The establishment of the number of wiring layers, ground planes, and power planes of the multi-layer PCB is related to the...

Provides PCB design, PCB layout, PCB prototyping and PCB assembly services 1. Design elements of gray-black multilayer PCB circuit boards...

There are some pretty amazing benefits to using flexible PCBs. Some of the advantages of flexible PCBs include the following: Reduced Space and Weight: Most of the advantages associated with flexible PCBs come from their low volume and weight. In fact, using a flexible PCB instead of a rigid PCB can result in a space reduction of over 50 percent and...
