Why there have different PCB color ?
PCB color is the pigmented lacquer that manufacturers coat printed circuit boards with. This is usually the color of solder mask. But there’s also another layer called silkscreen. Since these layers are differently colored for trace and other visibility, well start by looking at the options for each. PCB Solder Mask Colors Solder mask is […]
What is resistance circuit?
Resistance refers to the resistance that current encounters in a circuit, or the ability of an object to obstruct the current. The greater the resistance, the greater the resistance to current, and therefore the less current. On the contrary, the smaller the resistance, the less resistance the current is subjected to, and thus the greater the […]
Raspberry Pi 4 vs Raspberry Pi 5: In-depth comparison of hardware performance
Raspberry Pi is a microcomputer based on ARM architecture, which has won the favor of developers worldwide with its credit card-sized size and powerful features. With the continuous advancement of technology, Raspberry Pi has also continued to release new versions, of which Raspberry Pi 4 and Raspberry Pi 5 are the latest versions of the […]
Detailed explanation of the application of various components in EMC
Starting from this section, we will focus on analyzing the applications of various components in EMC, typically including inductors, capacitors, magnetic beads, resistors, and magnetic rings. The first is the capacitor. 1. In EMC design, the characteristics of the aforementioned components are related to an important factor, such as frequency. Talking about capacitors, inductors, and […]
What Is the Difference Between PCBA and PCB?
What Is the Difference Between PCBA and PCB? Printed circuit board (PCB) and printed circuit board assembly (PCBA) are both important terms in the electronics industry. Some people use them interchangeably, but they are actually two distinct things. The main difference between these two terms is that PCB refers to a blank circuitry board, while […]
How to avoid SMT virtual soldering problem
The factory for assembling electronic products mainly includes two production lines: SMT surface assembly and DIP plug-in assembly. SMT is the process of attaching electronic components onto a PCB circuit board through a device, then heating them in a furnace (usually referred to as a reflow soldering furnace), and fixing the components onto the PCB board […]
The electrostatic protection is important on PCBA board
During SMT processing, electrostatic discharge can cause damage or failure to electronic components. With the improvement of IC integration and the gradual reduction of components, the impact of electrostatic discharge becomes increasingly severe. According to statistics, static electricity accounts for 8% to 33% of the factors that lead to the failure of electronic products, and […]
The Importance of Impedance Control in PCB design (and how to avoid Signal Integrity problems)
What is Impedance Control and Signal Matching Impedance control is matching PCB trace dimensions and locations with the properties of the substrate material to make sure that the strength of a signal traveling along a trace is within a required range. The continual increase in device switching speeds is confronting engineers with signal integrity(SI) problems and eventually, most devices are going to have to deal with SI issues. So, Printed […]
