Proton is defined as positive electricity, neutron is not charged, and an electron is negatively charged.At nominal conditions, the proton number and electron number of an atom
Identical, positive and negative electric equilibrium is measured, so externally showing uncharged phenomenon.But since external influence is such as friction or with various energy
The form effect of amount such as kinetic energy, position energy, thermal energy, chemical energy can make the positive negative electricity of atom uneven.Therefore, any two are different
It is separated again after the object contact of material, that is, can produce electrostatic.
The charge accumulated of electrostatic can generate high voltage, and high voltage is accumulated to a certain extent, will be discharged under certain conditions.
The rated value that this high voltage is usually born far more than electronic component keeps component breakdown, causes permanent damage.
Therefore, electrostatic is the formidable enemy of electronic product, all links in electronic product use process must all be taken anti-
Electrostatic measure prevents electrostatic breakdown.
Radio frequency (RF) coaxial connector is electrically connected as transmission line or isolated element, and transmission is frequency range 3,000
Radio wave between HZ ∽ 3000GHZ, when there is electrostatic, can transmit to generate on signal largely influences, or even leads
Cause the damage of equipment, so be badly in need of it is a kind of can the element of antistatic export electrostatic, it is ensured that equipment and the safety of signal transmission with
Stablize.
