1. Communication between purchasing staff and suppliers Explain in advance the inspection time, personnel composition, and the matters that need the cooperation of the circuit board factory in the inspection process. Some regular enterprises need PCB manufacturers to provide their basic information before factory inspection, such as business license, tax registration, Bank of deposit, etc., [...]
We all know that diodes are very small, some are as small as needles, but they are very useful, The application fields are also very wide. Diodes are used in LED lights, electronic appliances, train and car electronic system components, circuit boards and so on. What are the classification, functions and working principles of diodes? [...]
Circuit board production will be tested in the end. The most important of all kinds of tests is electrical test, which is the original demand of circuit board. A circuit board will eventually match with electronic products. If the electrical characteristics can not meet, this circuit board is a failed product. What factors affect the [...]
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 [...]
