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 […]

The production line of PCBA factory consists of many production equipments, each of which works differently, but the ultimate goal of each equipment is printed circuit board. Smt production equipment has the characteristics of full automation, high precision, high speed and high efficiency. What equipment does a complete and efficient PCBA processing plant mainly include? […]

Up to now, although the country has not put forward special requirements for the design of lead-free SMT circuit boards, and there is no industry standard for SMT circuit boards, it has become a consensus to advocate environmental protection design, and to consider the design concept of SMT circuit boards in terms of material selection, […]

FPC, also called flexible printed circuit board for short, is commonly known as FPC in the industry. It is a printed circuit board made of flexible insulating substrate (mainly polyimide or polyester film). It has many advantages that rigid printed circuit boards do not have, such as it can be bent, rolled and folded freely. […]

For most electronic engineers (EEs), circuit board design is a daily job. Although they have many years of PCB design experience, it is difficult to produce high-quality PCB design. There are many factors to consider. Let’s discuss seven factors that need to be considered in high-quality PCB design. If electronic engineers want to design high-quality […]

Nowadays, the trend of increasingly compact electronic products requires three-dimensional design of multilayer printed circuit boards. However, layer stacking raises new problems related to this design viewpoint. One of the problems is to obtain high-quality stack construction for the project. With the production of more and more complex printed circuits composed of multiple layers, the […]

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 radio frequency circuit on PCB. Unfortunately, even the best PCB designers are often discouraged from radio frequency circuit, because it will bring great design […]

The design of schematic diagram is the basis of circuit design. Only on the basis of designing schematic diagram can the circuit simulation of printed circuit board be carried out. The following briefly introduces the design steps of circuit schematic drawing by new scholars of Protel DXP2004SP2. It contains the following nine specific design steps: […]

Why should test points be added to circuit board design? Circuit board design plus test points are not needed in PCB production, but ICT test after PCBA is completed, which is to test whether there is any problem in circuit board welding and whether the performance meets the requirements. In the production of PCB, the […]

The design of single-sided PCB requires a lot of professional data and some physical knowledge, which can be said to be a comprehensive skill project. If you want to make a high-quality PCB, you need not only a solid foundation, but also sensitivity to impedance. The impedance involved in PCB mainly includes the following aspects: […]
