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 […]

The meaning of each layer of PCB board

PCB boards are usually composed of multiple layers stacked together, with each layer performing a different function. The following are common PCB layers and their meanings: Signal layer: The signal layer is one of the most important layers on the PCB board. It contains the signal transmission path between electronic components and realizes signal transmission […]

Incoming Inspection

1.Incoming Inspection Incoming inspection refers to the confirmation and verification of the quality of purchased raw materials, components, or products, that is, the quality is inspected through sampling when the supplier sends the raw materials or components, and the final judgment is made whether the batch of products is accepted or rejected. 2.Meaning IQC is […]

PCB-stackup-designguide | Fra materialevalg til stackup-design

Hvad er PCB-stackup? Under normale omstændigheder er det ikke nødvendigt at overveje PCB's lamineringsproblem, når man designer almindelige enkelt- eller dobbeltsidede kort. Normalt vælges et kobberbeklædt kort med en kobbertykkelse og en pladetykkelse, der opfylder designkravene, direkte til direkte behandling. Men når man designer et printkort med [...]
