The current circuit board is mainly composed of the following:
Pat te rn: The line is used as a tool for conduction between the originals. The design will additionally design a large copper surface as the grounding and power plane. The line and the drawing are made at the same time.
Dielectric: used to maintain
The goal of any thermal solution is to ensure that the operating temperature of the equipment does not exceed the safety limits specified by its manufacturer. In the electronics industry, this operating temperature is referred to as the "junction temperature" of the device. For example, in a processor, the term literally refers
The conductive hole Via hole is also known as the conductive hole. In order to meet the customer's requirements, the conductive hole of the circuit board must be plugged. After a lot of practice, the traditional aluminum chip plugging process is changed, and the white plate is used to complete
With the improvement of the functions of electronic components, various electronic products are constantly moving toward higher speeds. However, as a result of high performance, multi-functionality, and portability, various EMC(Electro Magne ti c Compa TI bility) problems, It has become a lingering nightmare for designers.
At present, EMI (Electro Magne TI c In te rference) noise countermeasures mostly
Now share a summary of the difficult issues of carefully crafted PCB design techniques
1 How to choose PCB board?
Choosing PCB boards must strike a balance between meeting design requirements and mass production and cost. Design requirements include both electrical and institutional components. This material problem is usually more important when designing very
The process of resin plugging has been widely used in the PCB industry in recent years, especially in some products with a high number of layers and large thickness of the board. It is desirable to use resin plug holes to solve a series of problems that cannot be solved by
Collaborative design includes a series of great tools that enable clear visibility, difference comparison, and selection and merging. The functions and interactions seen by end users are just the tips of the iceberg of collaborative design. In fact, the back end of the collaborative design system determines its effectiveness. A well-organized core
PCB (Prin Circuit Board), the Chinese name for the printed circuit board, also known as a printed circuit board, is an important electronic component, is the support of electronic components, is the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is called a
To determine whether a signal is a high-speed signal, you must first distinguish between several misunderstandings.
Misunderstanding 1: The signal cycle frequency FCLOCK is high and belongs to high-speed design.
In fact, the highest frequency we consider when designing often depends on the effective frequency of the signal (also known
Electronic products do ESD testing. From the test results of different products, this ESD is a very important test: if the board design is not good, when the static electricity is introduced, it will cause the product to crash or even damage the components. Previously only noticed
