    1. The human body type means that the friction between the body and the clothes generates a triboelectric charge when the human body moves. When people hold ESD-sensitive devices without first placing charge on the ground, the triboelectric charge will move to the ESD-sensitive device and cause damage.2. The charged type of microelectronics refers to both ESD-sensitive devices, especially for plastic parts. When automated production, triboelectric charges are generated, and these triboelectric charges are quickly discharged through a low-resistance line to a highly conductive, solid ground. Th...

    Grip of the soldering iron: There are three types:1) The anti-grip method is to hold the handle of the soldering iron in the palm with five fingers. This method is applicable to high-power soldering irons, and is connected to the welded parts with large heat dissipation.2) Positive grip method, the electric soldering iron used in this method is also relatively large, and most of them are curved soldering iron tips.3) Holding the pen method, this method is suitable for low-power electric soldering iron, welding parts with low heat dissipation, such as welding radio, printed circuit board of TV ...
