. The specific capacitance is best for the same noise compensation as the self-resonant frequency, and we measure this phase relationship with this frequency. When the disturbance zone to the distance of the capacitance, the phase of the compensation current and the noise source phase is exactly the same as 180°, that is, the full reverse phase, when the compensation current is no longer in effect, the decoupling effect is invalid, the compensated energy can not be delivered in time, in order to

component encapsulation, and dip8 is double-row, each row has four pins, the distance between the two rows is mil, the distance between the pad is 100mil. Sipxx is the encapsulation of a single row. And so on. It is worth noting that the packaging of transistors and variable resistors is the most headache. the PINs may not be the same for the same packaging. For example, for packaging such as TO-92B, usually 1 foot is E (emission pole), and 2 feet may be B (base pole), or C (collector ); simil

Take Altium Designer 6.9 for example:1. Click Dxp→run Script.2. Click Browse to open: ad's installation directory under \altium Designer 6\examples\scripts\delphiscript scripts\pcb\pcb Logo Creator\ PCBLOGOCREATOR.PRJSCR file3. Select Runconverterscript, then click OK.4. load the BMP file and select which layer you want to put on the PCB, click OK, and that's goo

The next-door King has already talked about the principle of TDR and how to determine the TDR resolution. So, we have to correctly measure the circuit impedance on the PCB board, and what needs to be noted?1, the impedance Test industry standardsHave posted a lot of impedance test pictures, re-paste a picture for everyone to see. Impedance is not an imaginary straight line, but a downs. In the front and back end will be affected by the probe or open c

This semester we learn the operating system, so we have to write a PCB.So I borrowed a bit of Windows PCB, wrote thisImportsSystem.Runtime.InteropServices" " " "This is the legendary PCB."

Open the schematic and the corresponding PCB, click Pads Layout in the toolbar to connect the schematic and PCB.Right-Select the original in the schematic to select a module, and then right-click on the PCB to select a module to put together.When moving, rotate the originals by pressing the TAB key, Ctrl+e move the originals, and press Ctrl+r in situ.

is actually painted the most tangled piece of PCB, the left wiring is very easy, but the right 32 chip to FSMC, there are a lot of out of the IO port, cross-tangled together, there are a few lines all the way to hit 3, 4 through the hole, it is difficult to cloth.Engineering Check the next is the June 17 painting schematic diagram, today, at noon, and then today 3 o'clock in the afternoon to vote for Gali, almost two weeks of time, although there are

2004 accompany the German customers to visit the manufacturers, walked a circle, and finally to the PCB factory. Still the dirty, I took them a quick lap into the factory's conference room. Before, the German foreigner asked me to accept the "Gerber" file? I had no idea what he was talking about, so he replied that I needed the CAD file and he looked embarrassed. I sent to the factory is all the Protel format of the

interference refers to the interference source passing through spaceCouple the signal (interference) to another electrical network. In the design of high-speed PCB and system, high-frequency signal lines and integrated electricalChannel pins and various connectors may become radiation sources with antenna characteristics, which can emit and affect electromagnetic waves.The normal operation of the system or other subsystems in the system.Since the eme

This is an assignment in the operating system class. I attended the course. Maybe it is because of the attendance that I always hold on to the task with a single delay, I have no idea about my homework in this course. This process scheduling job has already been handed in. I want to write some programs over the past two days. By the way, I will update the content in my blog. If you talk less, you can write more comments instead of organizing the language. Basic Structure: Use the data structure

The computation of PCB streaming capability has always lacked authoritative technical methods and formulas. Experienced CAD engineers rely on their personal experience to make more accurate judgments. However, it is difficult for new users to use CAD. The current Loading Capacity of PCB depends on the following factors: line width, line thickness (copper foil thickness), and allowable temperature rise. As

Because our circuit board obviously cannot use the auto-wiring function, we should pay attention to the price of moving components at a time, especially holding computers with ultra-slow speed. While our PCB Board is still relatively complex, with many layers, multiple channels, and more room. Therefore, we need to fix the key devices or room, to avoid unnecessary movement of components. In the PCB, this i

1. Signal line do not take the corner, go straight. 2.PCB, at right angles there will be radiation effects, electromagnetic compatibility problems. 3. Follow the modular layout and regional layout. 4. Line thickness consistent, otherwise it will heat uneven, welding problems. 5. Ground mode, single point grounding, multi-point grounding. 6. Determine where the noise comes, first exclude peripheral devices, and then eliminate the program, and fina

0 Preface PCB drawing process is undoubtedly a big head, when the end of the long wiring phase, you also need to add a beautiful screen for your components, the end of these work and the last few steps need attention, this time to summarize the PCB post-processing work and inspection work. 1 Check that the device is fully positionedAn easy way to do this is to select the menu display->status to see if the

Wave automatic soldering technology has been used in the electronics industry for many years, but the late failure of solder joints is still a headache, which greatly affects the quality and reputation of electronic products.This paper intends to make a preliminary study and discussion on the basis of practical experience.The so-called "late failure of solder joints", refers to the surface appears to be the quality of the solder, there is no "lap welding", "Half welding", "pull the point", "copp

1 : no function is provided in the circuit. It is only for convenience of debugging or Compatibility Design on the PCB. 2 : Jumper can be used. If a line is not used, do not paste the resistor directly (without affecting the appearance) 3 : when the matching circuit parameters are uncertain, use 0 ohm instead. during actual debugging, determine the parameters, then, it is replaced by a component of a specific value. 4. when you want to test the
