Safety Precautions
1-2. ESD(Electrostatically Sensitive Devices) Precaution
Several semiconductors may be damaged easily by static electricity. Such parts are called by ESD
(Electrostatically Sensitive Devices), for example IC,BGA chip etc. Read Precaution below.
Protect you from ESD damage by static electricity.
― Remove electrical charges emitted by the human body before you touch semiconductors or parts.
There are ways that you touch an earthed place or wear static electricity prevention string on wrist
to prevent these problems.
― Use a earthed soldering steel when you connect or disconnect ESD.
― Use a soldering removing tool equipped with static electricity isolation. Otherwise ESD will be
damaged by static electricity.
― Don't unpack product until you set up ESD in the product. Because most of the ESD is packed by
box and aluminum plate to have conductive power, it is prevented from static electricity.
― You must maintain electric contact between ESD and a part to be set up until ESD is connected
completely to the proper place or a circuit board.
