What are the trends in the pcb board manufacturing industry? What potential technical issues does the pcb board manufacturing industry bring to PCB boards? What technologies and trends does the fast-moving consumer goods industry bring? Today, let me introduce to you the potential technical issues that the pcb board manufacturing industry brings to PCB boards?
What trends will emerge in the pcb board manufacturing industry? What are the trends in the development of the PCB board industry now? There are some reasons for the changes. For example, subjected to significant changes in time and heat. Obviously, a process that is subject to significant changes cannot solve problems with minimal knowledge, which may involve electronic products facing many problems. For example, heat issues.
Exposure to different types of substrates can result in different power supply networks (LANs). Use different physical media to generate power and frequency. Dividing the simulation module into source sources is called an analog power module (SpOxant).
Analog power supply, the most common analog power supply is AC-DC, because relevant factors are considered when designing the power supply, the remaining can be understood as.
The proposed power supply should not have rechargeable capacitors and inductors. Only capacitors with voltage resistance and insulation between the line and transformer design can ensure the stable performance of the capacitors.
The proposed power supply also needs to meet the relevant EMC requirements, namely the ability to suppress conducted disturbances, in order to require the power supply to provide lower noise interference without generating radiation.
If the signal propagation ability of electricity is lower than 1MHz and the grounding impedance is low, it can be filtered out through the front stage adjustable capacitor.
Capacitor filtering is the DC voltage provided by the RC circuit on the capacitor, as the withstand voltage value of the capacitor is consistent with the voltage value used.
The two important parameters of capacitor filtering are the capacitance reactance and capacitance, so when a capacitor is placed close to it, it will have an impact on the capacitor and affect the normal operation of the circuit.
The selection of capacitors requires consideration of two principles: lifting, lowering, decreasing trend, and filtering differences.
Generally, the larger the capacitance, the greater the electrical capacity at low voltage. When selecting a capacitor, pay attention to its maximum withstand voltage.
Withstand voltage is also the maximum withstand voltage of a capacitor, usually up to 20V, with the most common being 150V.
Ultra small electrolytic capacitor can not be used in high-power occasions, and high-frequency polymer Polysa is selected.
High frequency series, below ECE, are ZC series capacitors, which cannot be applied in high-power and high-power situations.
