High speed PCB, line is more than just connecting two points. As a qualified engineer, it is including resistance, capacitance and inductance of the hybrid knowledge carrier. During transmission line will be a reflection phenomenon, this must look at the size of the load end reflection depends on transmission line and load the Z Z. [...]
Transient Voltage suppression diode TVS (Transient Voltage Suppressors) is also called the Transient Voltage suppression diode breakdown diode, two-way, hereinafter referred to as TVS diode. Transient voltage suppression diode is in stabilivolt technology developed on the basis of a new device, the circuit symbols and ordinary zener diode, same appearance also with ordinary diode. The [...]
In the recently held "2018 China's integrated circuit industry promotion conference, deputy director general of ministry of industry and information technology electronic information Wu Shengwu said, integrated circuit is the basis of the information technology industry and the core, supporting economic and social development and national information security strategic, fundamental and pilot industry, speed up [...]
Intelligent sensor is to replace and biological sense organs and expand its function and design of a kind of device. And the feeling of organisms, there are two basic functions: one is the test object or object detection transformation of signal; Another kind is to judgment and reasoning, appraise the state of an object. The [...]
American Bourns world famous electronic components, led manufacturing suppliers, liam byrne, today introduced a microelectromechanical system (MEMS) environmental sensors, Bourns precision sensors (BPS) series products are three series of pressure sensor and a humidity sensor series. The series provides high sensitivity/accuracy, the long-term reliability, high temperature and medium bad compatibility, specifically designed to meet the [...]
Usually after the completion of the production of printed circuit board requires PCB board factory to carry on the processing production system, such as PCB proofing is completed, the technician will components welding, finally in the assembly to the case, form a complete packaging. Then the PCB proofing related parameters and instructions needed what? 1, [...]
1, more flexible plate structure Although in principle combined with hard and soft board can use all sorts of cascade structure, but if failed to think carefully about PCB PCB manufacturer production steps and material properties, its cost would be ridiculously expensive. Flexible circuit design is an important consideration, to understand the circuit when bending [...]
Electronic products will damage the continuous use, any especially, damage to the goods is not completely waste, however, can be recycled, PCB is the same. And, along with the progress of science and technology, the number of electronic products has increased dramatically, the life cycle shorten constantly, many products are not damaged will be discarded, [...]
In recent years, with automatic and intelligent demand rising, robot is more and more frequently appear in our life and production, from the industrial robot, service robot to all kinds of special robot, their type is more and more diverse, more and more powerful, services become more and more wide. But no matter how to [...]
What kind of PCB is a good PCB One aspect to satisfy at least the following 1. Low power interference is small, the key left line and the bottom line is reasonable, stable performance all aspects (premise is circuit without defects). 2. Good for EMC, low radiation, the loop is reasonable. 3. To meet the [...]
