FR - 4 epoxy glass fiber cloth substrate, based on epoxy resin as binder, with electronic level glass fiber cloth as reinforcing material of substrate. Its bonding sheet and thin copper-clad r.p. panel and inner core is an important base material in production of multilayer printed circuit board,This kind of product is mainly used for double-sided PCB, dosage is very large. Epoxy glass fiber cloth substrate, the most widely used model for FR - 4, in recent years because of the electronic product installation technology and PCB technology development needs, appeared high Tg FR - 4 products.

In a circuit with resistance, inductance, and capacitance, the impediment to AC is called impedance. Impedance commonly used Z said. Impedance by the resistance, inductance and capacitive reactance composed of three, but not a simple sum of the three. The unit of impedance is Europe. In DC, the object of the role of resistance to the current called the resistance, the world has all the resistance of the material, but the difference between the size of the resistance value only. Very small resistance material known as a good conductor, such as metal; great resistance material called insulator, such as wood and plastic. There is also a kind of conductor between the two is called the semiconductor, while the superconductor is a resistance value is close to zero material. But in the field of alternating current in addition to the resistance will hinder the current, the capacitance and inductance will hinder the flow of current, this effect is called reactance, meaning that the role of resistance to current. Capacitance and inductance of the reactance are called capacitive and inductive reactance, referred to as capacitive reactance and inductive reactance. Their units of measurement and resistance is ohm, and its value is the size and the frequency of AC has a relationship, the higher the frequency of the capacity of anti-smaller anti-larger, the lower the frequency capacity of the larger anti-anti-smaller anti-sense. In addition, the capacitive and inductive reactance has the problem of phase angle, with the vector on the relationship, it will say: impedance is the resistance and reactance in the vector and. For a specific circuit, the impedance is not constant, but with the frequency changes. In the resistance, inductance and capacitance series circuit, the impedance of the circuit is generally greater than the resistance. That is, the impedance is reduced to a minimum. In an inductive and capacitive parallel circuit, the impedance increases to a maximum when resonating, as opposed to a series circuit.
