Product Name: ESD (Electro-Static Discharge)
ESD (Electro-Static discharge) means ‘electrostatic discharge’, ESD is formed since the middle of the 20th century to study the generation of static electricity, hazards and electrostatic protection and other disciplines. Therefore, the international custom will be used for electrostatic protection equipment collectively referred to as ESD, the Chinese name for the electrostatic impedance. Chip capacitors
IEC61340-5-1:2007 standard is ESD S20.20:2007 in addition to another new international certification standards for anti-static, IEC61340-5-1:2007 standard is updated through the ESD S20.20:2007 standard, European and Japanese companies will be more inclined to the certification of IEC61340-5-1 standards, the Customers certified to ESD S20.20:2007 can easily convert their ESD systems to IEC61340-5-1:2007. ESD is applicable to electrical and electronics, IT and telecommunications, and automotive industries. Crystal Oscillators

Basic methods 1. grounding Grounding is the static electricity through a line of connection into the earth, which is the most direct and effective anti-static measures. Conductor commonly used grounding methods are: with anti-static wrist and work surface grounding. 2. electrostatic shielding electrostatic sensitive components in storage or transport process will be exposed to static electricity in the region, with electrostatic shielding methods can weaken the external electrostatic impact on electronic components. The most common method is to use electrostatic shielding bag as protection. 3. Ion neutralisation Insulators are often prone to static electricity, the elimination of static electricity on insulators, grounding methods are ineffective, the method usually used is ion neutralisation, that is, the use of ion fans in the work environment, ion air guns.
