The process of PCB board copying is to realize the rapid update, upgrading and secondary development of various electronic products by extracting some modifications and modifications in the technical data files. According to the document drawings and schematic diagrams extracted from board copying, upgrading and optimization can be carried out! What are the reverse steps [...]
Flexible circuit board cutting equipment is the main machine for FPC board processing. It mainly uses ultraviolet laser as the light source for cutting. It irradiates the material surface through high-energy laser beam to make it gasify and fuse to form cutting. Its following four characteristics solve the main processing difficulties of FPC board. Improve [...]
Why is laser equipment the Savior of PCB processing industry? Circuit board is an indispensable part of 3C industry. It is an important component carrier and line connection carrier. In this era of rapid development, efficiency has become particularly important. In industrial manufacturing, laser cutting machine has undoubtedly become the representative of efficient tools. China's [...]
As a bridge carrying electronic components and connecting circuits, circuit board is the basic component of almost all electronic products and plays a key role in the quality and performance of electronic products. Electronic circuit board is also developing steadily in the demand of the rapid development of domestic electronic equipment. So what problems will [...]
Circuit board can also be called printed circuit board or printed circuit board. The function of circuit board is to miniaturize and visualize the circuit, and plays an important role in the mass production of fixed circuit and optimizing the layout of electrical appliances. So how do circuit boards look at the direction of the [...]
1、 Foreword In PCB design, crosstalk generated by strong interference signal lines and signal lines sensitive to interference will exist between routing lines. This adverse effect is not only related to clock or periodic signals, but also affects other important routing, data lines, address lines, control lines and IO in the system. Most of the [...]
When selecting a circuit board manufacturing company, professional manufacturers should be selected through comprehensive comparison. The circuit boards produced by professional manufacturers are more affordable, have strong quality guarantee, and are relatively more guaranteed after-sales; Therefore, choosing an enterprise with strong PCB batch production service capacity is obviously less risky. The following small series will [...]
I believe that friends who have repaired more circuit boards must have encountered a short circuit of public power supply. In most cases, when you use a multimeter to test the resistance value between a power supply voltage of the circuit board and the ground, the display is very small, tens of ohms, a few [...]
PCB (printed circuit board), also known as printed circuit board and printed circuit board in Chinese, is an important electronic component, the support of electronic components and the provider of electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board. With the smaller and smaller requirements of [...]
1. Pay attention to reset when there are large-scale integrated circuits on the circuit board to be repaired 2. Before the test, it is best to install the equipment back, turn on and off the machine repeatedly, and press the reset key several times 3、 Function and parameter test 1. < tester > the detection [...]
