Design PCB Analog/Digital Circuit starts from dividing its structure into four types of circuits (RF analog signals, interface circuits, common digital circuits, -48V, power supply and other high-power wiring areas) to reduce mutual interference between various types of circuits and improve resistance to interference outside the equipment and reduce external emissions. The long-distance reset line…
Digital & Analog Circuit Design Requirement is critical important in the process of PCB Design, The circuit board should be divided into four types of circuits (RF analog signals, interface circuits, common digital circuits, -48V, power supply and other high-power wiring areas) to reduce mutual interference between various types of circuits and improve resistance to…
Design PCB Time Clock Component Layout has some skills which can help to optimize the PCB performance and increase the reliability of the system: 1, crystal, oscillator and related circuits should be placed in the center area of the PCB, not close to the I / O interface or board edge. 2, The clock circuit…
Power Supply PCB Board has been commonly used in the electronic device, as a result of that, a good layout will help to provide high efficient energy to the whole system, unfortunately not all of the power supply board is capable of it, so it is necessary to Reverse Engineering Power Supply PCB Board layout…
When we get the circuit board, we must first read the schematic diagram. After understanding the schematic diagram, we can start to reverse engineering circuit board. The main idea of circuit board schematic diagram reverse engineering should be according to the signal flow direction, so that the flow of the signal is as smooth as…
About MOSFET has always been one of the topics that engineers of circuit design are keen to discuss, and manufacturers want to see how to Choose New Mosfet to Improve PCB Performance. In actual work, when encountering various electrical equipment, damaged electronic components should be replaced with the same type of components, and this is…
The maximum junction temperature that any heat source component can withstand is limited. as a result of that, it has become extremely important for Component Thermal Operation reliability Analysis. This maximum junction temperature can be found in the datasheet given by the manufacturer. If the junction temperature of the actual operation of the heat source…
There are many conventional methods for PCB Board Thermal Design, such as: hot spot dispersion; the device with the largest heat generation is placed at the optimal position for heat dissipation; the high heat dissipation device should minimize the thermal resistance between them when connected to the substrate; each layer of the PCB It is…
Power Component in PCB card Layout can greatly help to decrease the noise, proper arrangement for MOSFET and capacitors (input, sidewalk and output) are important. as we all know that the current waveform at the top and bottom power switches is a pulse with a very high δI/δt. Therefore, the path connecting the switches should…
PCB board physical planning is very important, the current loop area must be minimized, and the power supply components must be arranged so that the current flows smoothly, avoiding sharp corners and narrow paths. This will help reduce parasitic capacitance and inductance, eliminating ground bounce. Below Figure shows the PCB board layout of a dual…
