Today let’s learn about several common methods for removing conformal coating from a PCB, each with its specific application scenarios and advantages. 1. Using chemical solvents 2. Micro-abrasion 3. Mechanical method 4. Desoldering through the protective coating

Today we will continue to learn about the precautions of conformal coating process.

It have been a long time since we send out our new products, here it is! The new PCB is made by Rogers material, and using lead-free hot air solder level technique.

So let’s continue to talk about which parts and components that can’t be covered by conformal coating. 1.Heat dissipation related components 2.Specific resistance components 3.Electrical connection and adjustment components 4.Sound and display components 5.Power and protection components 6.Interface and connection components 7.Light-emitting diodes (LED) 8.Grounding components

Let's continue to learn about the common quality requirements of conformal coating. 1.No runs and drips 2.Coating uniformity 3.Coating and component surface quality 4.Local isolation areas

Let's continue to learn about the specific operational requirements. 1.Work environment 2.Personal protection 3.Tool and container handling 4.Circuit board handling

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.
