In the previous article, we explained the specific functions and applications of conformal coating. Next, we will discuss the process specifications and requirements for applying conformal coating step by step.

It is well known that the surface of some PCB products is very smooth, can reflect light, and is often more durable than general PCB products. So, how is this achieved? The answer is that manufacturers use a special coating called conformal coating. Today, let's look at how conformal coating makes PCB "shine brightly."

Let's continue learning how to remove components from multi-layer PCB. Removing components from multi-layer printed circuit boards: If you use the methods mentioned in the previous article (except for the solder flow soldering machine method), it will be difficult to remove and can easily cause connection failures between layers.

After installing electronic components on a PCB, you may need to remove them from the PCB due to reasons such as component incompatibility or damage. However, for most people, removing electronic components is not an easy task. Today, let's learn how to remove electronic components.

Let's continue to learn about the factors that affect the etching factor in ceramic PCB and how to adjust the etching factor to manufacture high-performance ceramic PCB.

Today, let's understand what the etching factor is in ceramic substrates. In ceramic PCB, there is a type of PCB called DBC ceramic PCB, which refers to Direct Bonded Copper ceramic substrates.

Today, we continue to discuss the performance characteristics of 99% aluminum oxide. Compared to 96% aluminum oxide, 99% aluminum oxide is a high-quality material with a very high purity of aluminum oxide and minimal chemical impurities. It is mainly used in ceramic PCB that require excellent mechanical, electrical, thermal performance, or corrosion resistance to cope with harsh operating environments.

Let’s continue to learn the difference between 99% aluminum oxide and 96% aluminum oxide. We will start from 96% aluminum oxide......

In the design of high-performance electronic PCB, selecting the right materials is crucial. Among the various available options, aluminum oxide (Al2O3) stands out as an excellent choice for ceramic PCB due to its outstanding thermoelectric properties. However, not all aluminum oxide substrates are created equal. In this and several subsequent news articles, we will delve into the subtle differences between two common variant materials: 96% aluminum oxide and 99% aluminum oxide. We will explore the uniqueness and advantages of the two different materials.

Let's continue to learn about three other testing methods: ICT Testing, Functional Testing, and X-RAY Inspection.

Today, we will introduce four testing methods for PCBA after SMT placement: First Item Inspection, LCR Measurement, AOI Inspection, and Flying Probe Testing.

In the SMT production process, there is a common error prevention method that can reduce the risk of wrong parts, decrease the chances of errors, and effectively improve the quality of the entire production. This method is known as FII, which stands for first item inspection.
