Transmitters have two main PCB design goals: the first is that they must emit a specific amount of power while consuming the least amount of power possible. Second, they cannot interfere with the normal operation of transceivers in adjacent channels.
With the development of the electronics industry, the demand for printed boards is getting higher and higher. Printed board design of high density, thin wire, small aperture trend faster and faster, printed board production process is becoming more and mo
The main components of the bath are copper sulfate and sulfuric acid, and the formula of high acid and low copper is adopted to ensure the uniform thickness distribution of the plate and the deep plating ability of deep holes during electroplating.
Especially in sophisticated analog systems, special attention should be paid to the adverse effects of the temperature field generated by these devices on the fragile pre-amplifier circuit.
Zte is supported by China's National Integrated Circuit Industry Investment Fund, which undoubtedly speeds up the process of ZTE's independent research and development of chips; Before this, Huawei has launched its own Kirin 950 chip, which intends to com
In this environment of multi-project concurrency, high technology, rapid change, and limited resources, failures and setbacks are common. As companies are always struggling to meet changing market demands and face various challenges, they need to consider
Hongyunlai Electronic reverse R & D Center has a professional PCB board team, has rich experience in PCB board modification, PCB design, secondary development, and its board products involve communications, radar, automotive, medical, aerospace and ot...
in reality, due to economic considerations, PCB manufacturers cannot test every circuit board after every process. Therefore, process engineers and quality control managers must carefully consider how best to balance their investment in testing with the b
The Chinese name of SMT chip processing (PCB) is called "printed circuit board", also known as printed circuit board, printed circuit board, is an important electronic component, is the support body of electronic components, is the provider of e...
In this example of a four-layer PCB board, the designers used a solid ground plane located directly below the device, and the board was divided into analog and digital sections to keep sensitive inputs and reference signals away from noise sources.
This is because the PowerPCB database is too messy, which may be caused by too many modifications. To solve the problem, export the *.asc file and import it again.
It is important to note that the final performance rating (assembly, welding, cleaning and testing) of a PCBA cannot be higher than the performance rating specified for a bare board or prefabricated PCB. Therefore, to obtain a Class 3 PCBA, IPC Class 3 mu
