After plastic sheet laminated fr4 gradually replaced 3240 epoxy sheet, the market demand is also slowly increasing, because it has good flame retardance, insulation, which can meet the requirements of a lot of electrical equipment, pad, fixture and other requirements. So how does the insulation board manufacturer produce FR4 dielectric material? What's the production process like? Let's take a look.

First, resin and curing agent for mixing operation, halogen-free treatment. This process involves the formula problem, the effect will be different, that is why the price, quality and use of the same plastic sheet laminated fr4 sheet are different.

Second, the central control inspection, gluing. The size of the gluing machine also reflects the strength of the plastic sheet laminated fr4 manufacturers to a certain extent. The 15 meter gluing machine is basically the entry demand.

Third, assembly line operation. Slicing, material preparation, combination, plate matching, pressing, edge cutting, etc.

Fourth, packaging storage. This packaging is to prevent fr4 epoxy glass plate surface scratches and other impact on the subsequent processing.

It may sound simple for insulation board manufacturers to produce fr4 dielectric material, but the actual process requires precision and complexity. As the insulation board manufacturers, ZTelec Group will also strive for excellence, and have continuous innovation.
