FR4 epoxy board is also the representative material in electrical materials. A few days ago, I shared with you the technical parameters, performance characteristics and uses of FR-4 epoxy panels. Today I would like to share with you the characteristics of its manufacturing process.
Process characteristics of FR-4 epoxy plate
(1) the melting point of the FR-4 process pressure plate (203 degrees C);
(2) high chemical resistance: good resistance to any chemical substances, which greatly delayed the service life of the board.
(3) low loss coefficient (Df 0.0025): the loss coefficient is small, and the effects of various environments and temperature are very small.
(4) stable and low dielectric constant (Dk 2.35);
(5) thermoplastic material.
The following is a simple description of FR-4.
In fact, FR-4 is a type of combustible material grade, which means that the resin material must be extinguished by the combustion state of a material specification, it is not a material name, but a material grade.
