Interference Measures in PCB Circuit Board Design If you’re looking for interference measures in PCB circuit board design, you’ve come to the right place. These measures include shielding, grounding, transmission lines, and low-pass filters. These measures can help prevent EMI and noise, as well as improve the performance of your electronic products. Shielding Shielding is an important part of the PCB circuit board design process. It prevents EMI, or electromagnetic interference, from interfering with the circuit board. EMI is caused by electrical signals, which are often higher in frequency than the circuit board itself. Metal shields or cans on the circuit board help to block this kind of interference. Shielding […]

How to Solder the Chip Components Hand soldering Hand soldering involves applying heat and pressure to the component to form a strong bond. Unlike wave or reflow soldering machines, hand soldering is done by an individual with soldering iron and a soldering station. Hand soldering can be performed on smaller components or for repair and rework. To begin soldering, hold the soldering iron tip on the chip’s lead or contact point. Next, touch the tip of the solder wire to the lead. Then, heat the lead and solder until the solder flows. Ensure that the solder covers the entire lead or contact point. To prevent tombstoneing, don’t hold heat on […]

6 Basic Rules of PCB Layout PCB layout involves designing a circuit with multiple layers. Some of the fundamental rules of PCB design are as follows: Avoid multiple ground planes. Make analog circuit signals direct and short. Avoid using three distinct capacitors on a single PCB. You can also read our articles on multi-layer PCB design and how to design a multi-layer PCB. Designing a multi-layer PCB When you are designing a multi-layer PCB, there are a few important things that you should consider. One of these is that the copper traces should maintain signal and power integrity. If they are not, then they could affect the quality of current. […]

EMI Degradation After Filling An Irrigation Pump There are two different ways to analyze EMI degradation after filling an irrigation pump: radiation and conduction. The EMI degradation after filling depends on the type of glue material and how the input grounding process is performed. The EMI degradation is worsened by ethanol and water. EMI degradation after filling EMI degradation after filling power supplies is often referred to as the ‘filling effect’, which describes the loss of EMI sensitivity after a power supply has been filled. The degradation is a combination of radiation and conduction. The ‘filling effect’ occurs because the materials that make up the power supply undergo a series […]

How to Use a Few Resistors to Improve the Accuracy of a Multimeter To improve the accuracy of your multimeter, you can use a few resistors and components. They should be held in place so that they stay in contact with the multimeter’s probes. Do not touch the resistors or components with your hands, as this will result in inaccurate readings. To avoid this problem, attach the components to a breadboard or use alligator clips to keep them in place. Using shunt resistors The resistance value of a shunt resistor is expressed in microOhms. The resistance of a shunt resistor is usually very small. Using this type of resistor improves […]
