In this article, the topology of buck, boost and buck-boost will be introduced from different aspects. Step down converter Figure 1 is the schematic diagram of asynchronous buck converter. The buck converter reduces its input voltage to a lower output voltage. When the switch Q1 is turned on, the energy is transferred to the output […]

With the continuous development and progress of electronic product technology, electronic products are gradually developing towards light, thin, small, personalized, highly reliable and multi-functional. Aluminum substrates and copper substrates are born in compliance with this trend. So, what is the difference between aluminum substrate and copper substrate? Generally, the aluminum substrate is single layer, which […]

One of the main purposes of circuit schematic design is to provide a network list for the design of pcb, and to prepare for the design of PCB. The design process of multi-layer pcb is basically the same as that of ordinary PCB, but the difference is that the wiring of the intermediate signal layer […]

Although many customers and friends have been deeply involved in the electronic industry for many years, as the saying goes: there are specialties in the technical field! Perhaps you are not sure about the real quality of PCB. Xiaobian has been working in the PCB industry for ten years. Today, I will simply talk to […]

Why is BOM so important in PCBA processing? In daily work, many customers who do PCBA processing will ask, do you have a BOM here? Why is BOM so important in PCBA processing? BOM means bill of materials. A BOM of a product, indicating how many spare parts are needed to assemble the product. All […]

Usually, customers need to ensure that product design can be seamlessly transferred from prototype manufacturing to mass production process. If there is a difference between the two, then the customer needs to bear the related costs and delays. Differences mean that extra costs need to be paid to eliminate them. In this process, new problems […]

PCB design or PCB layout requires the perfect integration of different technical capabilities. It is an indispensable link between manufacturing and engineering, so it determines the overall functional performance of the final product. For the same reason, it is always a better idea to seek experienced and skilled PCB manufacturing companies, which know how to […]

The design of printed circuit board is based on circuit schematic diagram, and realizes the functions required by circuit designers. The design of printed circuit board mainly refers to layout design, and the layout of external connections needs to be considered. Optimal layout of internal electronic components. Optimal layout of metal connecting lines and through […]

Single-Chip Microcomputer For novices, electromagnetic interference may not pay much attention to the influence of circuit design on the input and output of the design itself, but for an electronic engineer, it is self-evident. It is not only related to the ability and accuracy of MCU in control, but also related to the competition of […]

1、 Preface At present, high-speed PCB design is widely used in the fields of communication, computer, graphics and image processing, etc. All high-tech value-added electronic product designs are pursuing the characteristics of low power consumption, low electromagnetic radiation, high reliability, miniaturization and light weight, etc. In order to achieve the above goals, via hole design […]
