G10 Epoxy Sheet vs FR4: Which Insulation Material Should You Choose?

When it comes to choosing the best insulating material for your electrical or mechanical projects, the choice between FR4 epoxy sheetand G10 epoxy sheet might be quite important. Both materials are great insulation properties, but they have different features that make them better for different uses. Most people agree that G10 epoxy sheet is better than other types of epoxy sheet when it comes to mechanical strength, thermal stability, and moisture resistance. This makes it perfect for high-performance use in tough conditions. FR4 epoxy sheet, on the other hand, is more cost-effective and more common in the electronics industry, especially for printed circuit boards (PCBs). Your pick should be based on your needs, such as the temperature at which it will be used, the amount of mechanical stress it can handle, and your budget. To pick a wise option that works for your project, think about things like how well it works with electricity, how stable it is in size, and how easy it is to machine.
