When customers customize PCB products, they will produce more in quantity to prepare for they pcb projects. Over time, the PCB board will expire. So, what are the hazards of using expired PCB circuit boards? 1. Expired PCB fabrication may cause oxidation of surface pads Oxidation of the solder pad will cause poor soldering, which…
For general electronic products, FR4 epoxy glass fiber substrate is used, for use in higher ambient temperatures or for flexible circuit boards, polyimide fiberglass substrates are used, and for high-frequency circuits, PTFE fiberglass substrates are required; Electronic products with high heat dissipation requirements should use metal substrates. (1) A substrate with a higher glass transition…
Electronic chips play an important role in the field of electrification in our country. With the changes in our country’s market, electronic components play an important role in life, and Electronic multilayer PCB boards are the basic components of electronic components. Nowadays, the use of multilayer HDI PCB on the market has become a popular…
In daily life, the multi-layer PCB circuit board is currently the most widely used circuit board type, and it can have such an important proportion, which must benefit from the many advantages of the multi-layer PCB board. Advantages of multi-layer circuit boards: 1. High assembly density, small size and light weight, meeting the needs of…
1. Improper placement of components There are some high-power devices that need to be reserved for natural ventilation or forced ventilation, mainly to dissipate heat. If there is no airflow to dissipate heat well, the PCB Board will accumulate most of the heat, causing the temperature to rise, which in turn leads to degradation or…
PCB is a Printed Circuit Board. It’s an important electronic component, which is a support for electronic components and a carrier for electrical connections between electronic components. A electronics PCBA is a complete package; it has been fitted with all the necessary components(capacitors inductors, resistors, diodes, triodes, modules, and BGA’s) and is ready for deployment…
The pcb fabrication is prone to cause various problems in a humid environment, such as short circuit, circuit board signal open circuit, these failures are all. How to judge whether the pcb circuit board is wet? If the pcb circuit board is used in a humid environment, the air in this environment contains relatively large…
Many newcomers who are just entering the industry have doubts about the color of PCB boards, and do not know what color PCB base are of high quality. In fact, PCB manufacturing mainly provides the interconnection between components, and its color has no direct relationship with performance and quality, and the difference in color does not…
