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? 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 […]

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 […]

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 […]

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 […]

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 […]

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 istifleme nedir? Normal şartlar altında, sıradan tek veya çift taraflı kartlar tasarlarken, PCB'nin laminasyon problemini dikkate almaya gerek yoktur. Genellikle, bakır kalınlığına ve tasarım gereksinimlerini karşılayan bir plaka kalınlığına sahip bakır kaplı bir tahta doğrudan işleme için doğrudan seçilir. Bununla birlikte, bir PCB tasarlarken [...]
