When the discharge sound is maximum, this is the fault point. When using this method, it is important to pay attention to safety, and sellers must pay attention to the following points: rigid-flex boards!
The BAI diagram has always been a daily communication project for every customer, and is the preferred choice for our customers' needs, success of each product, discounts, and more.
The second method is to first claim and have the right to obtain it. Define a BAI on a product, which is the finished product diagram. If the product produced is scanned for QR code to generate BAI, and the subsequent products are solid-cut, if there are no products on the product other than NBOM process, we can further add some Stog after simplification.
Due to the application of 1-3 to 4-5 in other products, the main design product is hot glue/SAR/UV/metal color card.
There are still some main requirements, and now our products can reach 80% and can reach Class I. Because EMI shielding is required, the experience will increase, so we are looking forward to a solution.
However, the biggest drawback of EMI shielding is that it does not require magnetic shielding, resulting in reduced electromagnetic interference and product performance, as different products have different problems. All products have speed reduction situations, such as when a wire is placed near a coil and passes through the coil to which the wire is connected, the wire must pass through the coil.
EMI shielding is very easy to generate electromagnetic interference, such as generating abnormal frequencies and static electricity near the transformer and causing disturbance to the output. Due to the fact that EMI shielding is mainly suppressed through EMI, even controlling high-power small capacitors can suppress common mode interference in an extremely short period of time, achieving the goal of effectively suppressing common mode interference.
In order to achieve the goal of anti EMI, ceramic thin film technology is usually used, such as adding a composite layer of copper foil to the capacitor core, which increases the generation of common mode interference within the shielding range of EMI, as shown in Figure 1 and Figure 2.
We know that automotive electronics always have relatively low requirements for EMI. In order to reduce the interference of electromagnetic waves in the frequency band, it is necessary to ensure that the amplitude and purity of the signal reach 154-8 × 10 Ω, with a resistance of 17R~10 Ω due to its low resistance characteristic. When EMI increases to almost 20R, the comparison value also increases and RC increases.

The size of the matching resistor has an additional matching resistor, which has a resistance value of 0 01 Ω, and the matching resistors have resistance values of 1 Ω 01 Ω and 0 002 Ω.
RC will add a voltage divider to calculate 1 voltage divider. RC will increase slightly, and the voltage divider resistance will be smaller compared to the corresponding resistance.
RC will also add a voltage divider to calculate 1 voltage divider. The resistance value of the divider resistor is similar to the power of the divider resistor, so although the divider resistor has a certain amount of power, it only operates within the divider range, but has high power consumption.
