Notebook motherboard short-circuit reason analysis: Notebook motherboard short-circuit is only two possible, on the one hand, the motherboard itself is not good insulation, on the other hand may be the motherboard has foreign metal pieces (such as screws) lead to short circuit. Due to the limited volume, General notebook motherboards are stacked together by Mul

Building a differential amplifierAn op-amp and no feedback is already a differential amplifier, amplifying the voltage difference between the inputs. However, its gain cannot be controlled, and it's generally too high to be of any practical use. So far, we application of negative feedback to op-amps have resulting in the practical loss of one of the inputs, the ResU Lting amplifier only good for amplifying a, single voltage signal input. With a little ingenuity, however, we can construct a op-am

1. Circuit BreakerIn the microservices architecture, there are multiple microservices, there may be dependencies between each other, when a unit fails or the network is not available, it will cause the failure of the dependency of the spread, resulting in the overall system paralysis, relative to the traditional architecture more unstable. In order to solve this problem, the circuit breaker mode is produced

Preface This digest is self-aware. Question 0: Why can we separate the ground in a digital analog hybrid circuit? Some of my answers have not been approved by anyone before. If there is any infringement, please contact the blogger's email to delete it. Thank you.@ Operation amplifier answer The following is the original article: @ magic sub's answer is inaccurate for the following reasons:First, 0 euro resistance is not convenient for debugging. I hav

Abstract:The development of the signal processing circuit of the infrared focal plane array is introduced. The basic structure, working mode and application fields of CCD Multi-Channel transmitter (CCD-MUX), time delay integrated CCD (TDI-CCD), MOS and CMOS multi-channel transmitter (CMOS-MUX) are described. Finally, two application circuits of multichannel transmission devices are provided. Keywords:Signal processing

Introduction to three exchange technologies1. Circuit Switching TechnologyThe network switching technology has gone through four stages: Circuit Switching Technology, packet switching technology, group switching technology and ATM technology. Public Telephone Network (PSTN) and mobile network (includingBoth GSM and CDMA networks use circuit switching technology.

On printed circuit boards, power cords and ground wires are the most important. The main method to overcome electromagnetic interference is grounding. For the dual panel, the ground line layout is particularly exquisite. By using the single point grounding method, the power supply and ground are connected from both ends of the power supply to the printed circuit board. The power supply is one point, one poi

Most of the mobile power inside the use of lithium-ion batteries, when users operate or use improper, the battery may be due to a short circuit and then lead to security incidents, it has become an impact on the use of mobile power security a major hidden danger. The charging wire uses PVC plastic skin What is causing the short circuit of the mobile power supply? When an abnormal path occurs b

Overview With the development of science and technology, power electronic equipment and people's work, life, and the relationship between the increasingly close, and electronic equipment can not be separated from the reliable power supply, so the DC switching power supply began to play a more and more important role, and successively entered a variety of electronic, electrical equipment fields, program-controlled control equipment, such as power supply has been widely used in DC switching power

C can be summarized into the following sentences:Trust the programmer.Don't stop programmers from doing what they need to do.Keep the language short and lean.One way to do an operation.Makes it run fast enough, although it is not guaranteed to be portable.4, like the bottom development, hate the development of VB tools (not to say that VB is not good).5, the development of good prospects, suitable for entrepreneurship, do not want to die when it is an engineer.Method steps:1.

In the study of various resonant circuits, often involves the quality factor Q value of the circuit question, then what is the Q value? Let's make a detailed discussion below. 1 is a series resonant circuit, which consists of capacitance C, inductance L and the capacitance of the leakage resistance and inductance of the line resistance R. The complex impedance Z of this

Compared with VoIP, packet network circuit simulation business has more flexibility, shorter delay and simpler features, is the most competitive alternative to VoIP technology. This paper expounds the characteristics of the packet network Circuit simulation service, and analyzes how to make the best use of these characteristics and the possible applications to operators and enterprises. Despite the industr

The ion battery protection circuit includes overcharge protection, overcurrent/short-circuit protection and over discharge protection, requiring overcharge protection, high precision, low power consumption, high voltage and 0 volt charging characteristics.

FCT (functional testing) refers to a simulated running environment (incentive and load) provided to the testing target board (UUT: Unit under test) so that it can work in various design states, so as to obtain parameters of various States to verify the UUT function is good or bad test method. Simply put, it is to load appropriate incentives for UUT and determine whether the Output Response meets the requirements. Generally, it refers to the function test of pcba. Directory 1. Proof of the
