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 […]

Nanjing PCB design power supply noise The common interference source in the circuit comes from the power supply, and this interference signal is usually introduced through the power supply pin of the active device. For example, the timing diagram of A/D converter output in is shown in. The sampling speed of A/D converter is 40ksps, […]

With the rise of Internet of Things technology, it is more and more common for electronic products to be equipped with wireless communication function, and wireless communication technology is realized by RF circuit on PCB. Unfortunately, even PCB designers in Chengdu are often discouraged from RF circuit, because it will bring great design challenges and […]

The PCB is designed, sent to the board factory for processing, and the next step is “A” (Assembly), which is the process of welding and debugging as we often say. This process requires good soldering ability, correct use of testing and measuring instruments, and standardized debugging process. Finally, it is necessary to test the function […]
