The circuit board is broken. It can be repaired basically If there is only visible component damage, replace the component. If the circuit board is broken, and the circuit board can't see any damage, we should check the working conditions of each part according to the circuit diagram, and use the universal meter to check [...]
Automatic soldering machine has been widely used in the circuit board soldering industry, it improves the actual soldering efficiency, product consistency to a large extent, improve people's living consumption level, and put forward a higher level of consumer demand for product quality. In order to meet the market requirements, manufacturers should increase the product quality [...]
PC flexible circuit board with wiring of high density, light weight, thin thickness, good bending property characteristics, widely used in smart phones, FPC flexible circuit board of the smart phone is mainly used for the connection parts and motherboard, display module, fingerprint module, camera module, antenna, vibrator, etc., as the camera to three, four taken [...]
We are not too unfamiliar with drills. They are often used in our daily life and production. Ultra small drills are also widely used in the electronic industry. Recently, an ultra-fine micro drill with a processing diameter of only 0.01mm was successfully launched in Shenzhen, breaking the oligopoly control situation and becoming the world's smallest [...]
Introduction to FPC FPC: flexible printed circuit, which means flexible printed circuit board in Chinese. It is to make conductor circuit pattern by using optical imaging pattern transfer and etching technology on a flexible substrate surface. The surface and inner layers of double-sided and multi-layer circuit boards are electrically connected through metallized holes. The surface [...]
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 [...]
