PCB board, or printed circuit board, is commonly referred to as printed circuit boards. It is divided into cardboard, semi fiberglass, fiberglass, metal substrate and so on.
There are many kinds of glass fiber board, we get to know it first. FR-4 is also known as fiberglass board, glass fiber board, FR4 reinforcement plate, FR-4 epoxy resin plate, epoxy plate, epoxy glass cloth plate and line board drilling pad, generally used in soft base, outside package cloth,Leather and so on, make beautiful wall and ceiling decoration. The application is very wide. It has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, flame retardancy and so on.
Fiberglass panels are composite materials made of epoxy resin plus filler and glass fiber.
Features of fiberglass board:
stable electrical insulation, good evenness, smooth surface, no dent, more than standard thickness tolerance, suitable for high performance electronic insulation requirements, such as FPC reinforcing plate, high temperature plate for tin furnace, carbon diaphragm, precision travel star wheel, PCB test rack, electrical (Electrical) equipment Insulation baffle, insulation pad, transformer insulation, motor insulation, deflection coil terminal, electronic switch insulation board, etc.
Applications of fiberglass board:
Fiberglass panels are widely used in conventional electrical, electronic and digital products because of their good material properties. The price is higher than that of paper and semi glass fiber, and the specific price varies with product requirements. Fiberglass panels are widely used in digital electronic products.
Aluminum substrate is a metal based copper clad plate with good heat dissipation function. The general single panel is composed of three layers, which are the circuit layer (copper foil), the insulating layer and the metal base. For high-end use, there are also two sided designs, which are circuit layer, insulation layer, aluminum base, insulation layer and circuit layer. Very few applications are multi-storey plates, which can be made of ordinary multilayer boards and insulation layer and aluminum base.
Features of Aluminum substrate:
Aluminum substrate is one kind of PCB, aluminum substrate is a metal base printed board, with high thermal conductivity, usually used in solar energy, LED lamp and other products that need heat dissipation. Only the material of the circuit board is aluminum alloy. Before our general circuit board material is glass fiber, but because of the high heat of LED, the circuit board used for LED lamps is generally aluminum Substrate, can heat conduction fast, other equipment or electrical appliances circuit board or fiberglass board!
