It has a thermal cladding, which can efficiently dissipate heat, cool components and improve the overall performance of the product. 1。 Environmental protection: Aluminum is non-toxic and recyclable. Because it is easy to assemble, the use of aluminum also helps to save energy. For printed circuit board suppliers, the use of this metal helps to […]

With the rapid development of electronic information technology, the manufacturing requirements of various circuit boards have increased greatly. As the key raw material of anodizing in electroplating process, the demand of copper is greatly increased, and the high-precision PCB must be anodized with phosphor copper balls. Phosphor copper balls are mainly used in electronic devices […]

What problems should be paid attention to in the pcb Layout of mobile phones, and do the display parts need to be wired? 1: device device Layer2： signal Most of the address and data signal, and some analog lines (corresponding to the ground of layer 3). Layer3： GND part of the wiring (including the keyboard […]

Today, from the perspective of soldering, let’s talk about what points should be paid attention to when designing PCB. 1. Factors affecting PCB welding quality From PCB design to the completion of all components welding, to become a high-quality circuit board requires the control of PCB engineers, welding process, welding workers and many other links. […]

Include the development of PCBs that drive electronic devices and generally control mechanical and pneumatic operations. It brings special challenges to space PCB manufacturing, and these challenges must be overcome to ensure that aerospace systems can complete their tasks safely and reliably. For the manufacture of plates, these are mainly related to the maintenance of […]

Generally, the design current of PCB will not exceed 10A or even 5A. Especially in household and consumer electronics, the continuous working current on PCB usually does not exceed 2A. Recently, however, the company’s products should be designed with a power line, and the continuous current can reach about 80A. Considering the instantaneous current and […]

Etching process is one of the basic steps in PCB production. Simply speaking, it is the process that the base copper is covered by the resist layer, and the copper that is not protected by the resist layer reacts with the etchant, so that it is bitten off, and finally the design circuit pattern and […]

Matters needing attention in the design of the clock on the circuit board are mainly considered from three aspects. 1. PCB layout 1) the clock crystal and related circuits should be arranged in the center of the PCB with a good stratum, not near the I/O interface. The clock generation circuit can not be made […]

It is undoubtedly the goal of this product to have a PCB that can withstand any electrical, mechanical or structural adverse effects throughout its life expectancy. Circuit board construction process. These goals are equally divided between PCB manufacturing and PCB assembly. For manufacturing, the threat is cracking and breaking, while for assembly, the threat is […]

The analysis and design of power supply system (PDS) is becoming more and more important in the field of high-speed circuit design, especially in computer, semiconductor, communication, network and consumer electronics industries. With the inevitable further proportional reduction of VLSI technology, the supply voltage of integrated circuits will continue to decrease. As more and more […]
