What Are The Assembly Methods Of SMT Chip Processing
On SMT printed circuit boards, solder joints and components should be on the same side of the board.
PCBA OEM how to choose the chip inductor?
Different products, the selected coil diameter is different, the opposite inductance, the DC resistance is not opposite. In high frequency circuit, DC resistance has great influence on Q value
Aluminum substrate package and chip connection
At the same time, relevant associations should also actively lead, assist the government to seek more development space for the PCB industry, but also actively call on the awareness of energy conservation and environmental protection of enterprises, carry
SMT chip processing features
high temperature performance is good: most of today's SMT circuit boards need to install components on both sides. Therefore, the PCB machined by SMT needs to be able to withstand two reflow soldering temperatures. At present, lead-free welding is widely
How does SMT chip processing remove excess tin residue?
Manual cleaning method is one of the simplest and most primitive methods to remove excess tin residue. It is mainly manually operated, using hand tools (such as scissors, scrapers, spray guns, etc.) to clean up excess tin residue. The advantage of this me
How is the chip inductor and chip magnetic bead different in PCB circuit board
What is the circuit and load impedance? Whether there is space to place magnetic beads on the PCB board. The first three can be judged by observing the impedance frequency curve provided by the manufacturer.
PCB manufacturers talk about the significance and stakes of independent research and development of chips
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
The Chinese name of SMT chip processing (PCB) is called "printed circuit board"
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...
The basic elements of SMT chip processing technology
Another important consideration when designing automotive system boards is grounding. Since the vehicle is not in contact with the ground, its electronic systems must be designed to take advantage of chassis grounding technology
