Product introduction

Product introduction of FR4 G10 G11 Epoxy Board

FR4 G10 G11 are all epoxy glass fiber cloth laminates, which are laminated products made of chemically treated electrical alkali-free glass fiber cloth as the base material and epoxy resin as the binder. High mechanical strength and good electrical performance stability under high humidity.
FR-4 epoxy board: It is made by coating epoxy glass fiber cloth under high temperature and high pressure. It has high mechanical properties and stable electrical properties under high humidity. It is suitable for mechanical, electrical and electronic parts with high insulation structure. It has high mechanical and dielectric properties, good heat resistance and moisture resistance. Heat resistance class B
G10 glass fiber board: “G” in G10 represents glass fiber, 10 represents the content of glass fiber is 10%, G10 epoxy board is made by processing glass fiber cloth and epoxy resin. It has a certain mechanical strength without deformation, and has the characteristics of insulation, acid and alkali resistance. Good insulation strength, chemical resistance, radiation resistance and thermal shock resistance; good tensile strength, flexural strength and low temperature adaptability.
G11 laminated glass cloth board: G11 is similar to the G10 process, except that the glass fiber content is changed. Its main properties are the same, such as flame-retardant UL94-VO grade, good mechanical properties at high temperatures, and good processing and insulation properties. G11 epoxy board has stronger high temperature resistance and arc resistance

FR4 G10 Product Features

Epoxy glass fiber cloth board has higher mechanical properties, dimensional stability, impact resistance, and moisture resistance than paper substrates. The electrical insulation performance is stable, the flatness is good, the surface is smooth, no pits, and the thickness tolerance is standard. Its electrical performance is excellent, its working temperature is high, and its performance is less affected by the environment. In terms of processing technology, it is much superior to laminated glass fiber cloth boards made of other resins.
(1) Melting point of FR-4 process platen (203 ℃)
(2) High resistance to G10
(3) G11 low loss coefficient (Df 0.0025)
(4) Stable and low dielectric constant (Dk 2.35)
(5) Thermoplastic materials

Color G10 Laminate Production Process

The production of g10 epoxy glass cloth laminates goes through 4 processes. The first step is to immerse the glass fiber cloth in epoxy resin. The second step is to cut into PP sheets after drying. The third part, finishing and superimposing to the corresponding thickness. The fourth step, hot press
