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 […]

When it comes to PCB rush, everyone is no stranger! PCB is called “the mother of electronics” because it is the carrier of all electronic materials. Without this carrier, no matter how good the scheme is, it can’t be implemented! However, as a customized product, PCB has a long production process, complex production process and […]

When we get a PCB, how can we preliminarily judge its quality? As the saying goes, laymen watch the scene of bustle, while professionals watch the doorways. Here, Xiaobian shares a few details with you. Although these details can’t 100% show that the quality must be very good, if a board factory can control these […]

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

When it comes to 24-hour expedited PCB boards, many customers are familiar with it. Some people will say that 24-hour expedited PCB boards are nothing, and 8-hour expedited PCB boards are available! In fact, it can’t be done in 8 hours, unless there is a discount in some processes. Here, I’ll tell you how this […]

The clock in mobile phone can be roughly divided into logic circuit main clock and real-time clock.The main clock of logic circuit usually has 13m, 26m, and 19.5m;The real-time clock is generally 32.768KHz.The real-time clock frequency in mobile phone is basically 32.768KHz, which is generated by 32.768KHz crystal and other circuits.In order to maintain the […]
