PCB design after need SMT processing production line, the patch this link need on the circuit board with components, each SMT processing plant according to the requirements of the assembly line processing, circuit board is the most suitable size requirements, if size is too small or too large, fixed circuit board assembly line tooling cannot [...]
Winter is coming, the human body can release up to tens of thousands of volts of static electricity, the end of the project has also come to the end of the stage, we do not because of the hand carrying static electricity directly touch the motherboard and cause the motherboard to burn out! It is [...]
All major electronic components have a printed circuit board (PCB), which is the backbone of each component. Even the most basic devices (such as calculators and digital clocks) have printed circuit boards, and virtually all computing electronics have printed circuit boards as well. The purpose of printed circuit boards is to route electrical signals through [...]
Resistance welding flux is printed on PCB components before they are coated on plates. Its main function is to prevent "wiring" and short circuit during wave soldering and protect the PCB permanently. In addition, printing plants can also save solder, reduce the weight of printed circuit boards, reduce costs. The soldering flux has the following [...]
In the electronic product processing industry, the circuit board has three branches: hard and soft. The traditional circuit board is generally rigid circuit board, while flexible circuit board is a kind of printed circuit board with special functions, which is mainly used in mobile phone, notebook computer, PDA, digital camera, liquid crystal display and other [...]
Using X - ray can effectively detect the defects of PCB, such as soldering, adhesion, copper foil falling off. In order to meet the needs of our customers, UFJ has introduced a new X-ray examination system with high capacity, high resolution and high magnification. In BGA, CSP, flip chip inspection, semiconductor, package components, electronic connector [...]
Photo taken on Dec. 2, 2018 shows the International Electronic Circuits (Shenzhen) Exhibition 2020, with the theme of "5G Era and Smart Future", at the Shenzhen Convention and Exhibition Center in southern China's Guangdong Province. Joinly organised by the Hong Kong Circuit Board Association and the China Electronic Circuit Industry Association, the exhibition covers an [...]
PCB circuit boards, chip bracket, power supply circuit chips in our life, although not often meet directly, but generally exists in every aspect of our daily life, from chips, memory, power supply, switch machine, server, scientific instruments, such as special products to mobile phones, computers, televisions, air conditioners, refrigerators and other household appliances, literally open [...]
Principle of sound-light control delay switch circuit board: Acousto-optic control delay switch is mainly composed of sound control switch, light control switch and delay circuit. Voice control is to collect sound through the pole microphone, and generate pulse signal. The light-controlled circuit is controlled by photosensitive resistors. The resistance value of photosensitive resistors varies greatly [...]
The production process of circuit board is more complex, which involves a wide range of processes, from simple mechanical processing to complex mechanical processing, common chemical reaction, photochemistry, electrochemical thermochemistry and other processes, computer-aided design CAM and other knowledge. And in the process of production process problems and will always meet new problems and some [...]
