Aluminum-based PCB circuit board is a widely used circuit board in the PCB industry. It is also the cheapest among metal circuit boards and has good thermal conductivity. Aluminum-based PCB circuit board is the most cost-effective circuit board among many boards with heat dissipation performance. The aluminum-based PCB circuit board is divided into three layers. The upper layer is the wiring layer, the middle layer is the thermal conductive and insulating layer, and the lower layer is metal.

Based on many years of experience in PCBA maintenance and analysis, we have classified maintenance methods into seven categories. Today, we will not conduct a detailed analysis of the PCBA circuit diagram. Instead, we will give a general overview of several methods we often use in maintenance analysis. This method is as follows: 1. Visual inspection method Visual inspection is the basis of all maintenance. When I get a piece of bad PCBA, I

What are high-frequency boards and ceramic substrates? In PCB prototyping, high-frequency boards are mainly used in high-frequency and high-speed electronics, including 5G communication base stations, power amplifiers, ceramic filters, GPS high-frequency antennas, etc. So, what are high-frequency boards and ceramic substrates? What is pcb high frequency board? Pcb high frequency board is a special circuit board with higher magnetic frequency. Generally speaking, high frequency

In today's electronic product industry, PCB is the most indispensable key component of the entire electronic product. Since PCB manufacturing involves many fields, if you have not participated in the PCB production process during PCB design operations, it is conceivable that in the end it will directly lead to more emphasis on performance and functionality in the design process. Then in the factory production process , it will be caused by PC

Introduction to the principles, advantages and disadvantages of PCBA water cleaning technology. PCBA water cleaning technology uses water as the cleaning medium. A small amount (usually 2% to 10%) of surfactants, corrosion inhibitors and other chemicals can be added to the water. By cleaning, PCBA cleaning is completed through multi-source cleaning and pure water or deionized water drying. So today, the editor will introduce to you
