The meaning of the full name of epoxy board

We often talk aboutepoxy boardEpoxy board is just its abbreviation. In fact, its full name should be:Epoxy phenolic resin glass fiber cloth laminated boardWhen it comes to the full name, I think many people are already confused, but it doesn't matter. Let's break it down for nowepoxy boardThe meaning of the full name.

1. Epoxy resin, representing the adhesive of epoxy board, is epoxy resin glue.

2. Phenolic acid is its curing agent. Epoxy boards require phenolic curing agents to solidify into hard board assemblies.

3. Laminated board, this is something that most people can understand. It represents that it is made by high-temperature pressing with a press. Nowadays, there are generally two types of presses, one that burns coal and the other that burns oil. Of course, there is also electricity available. But now the country is becoming increasingly concerned about environmental issues. So, in the future, press machines will basically develop towards less pollution.

In our country, epoxy board is actually divided into two types: 3240 epoxy board and FR4 epoxy board. There is a difference between these two. It's too profound for everyone to understand. Let me briefly introduce it here. 3240 epoxy board is suitable for general insulation engineering or insulation components. FR4 epoxy board is suitable for insulation components with strong voltage breakdown capability. The mechanical processing performance and plasticity of the latter are also higher than those of the former. Some domestic enterprises have also developed a high-strength epoxy board. This high strength is only reflected in the mechanical processing tolerance. In terms of voltage breakdown, FR4 epoxy board is still better.
