1-2. ESD(Electrostatically Sensitive Devices) Precaution
Several semiconductor 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.
You can prevent from ESD damage by static electricity as following:
● Remove remaining static electricity on your body before you touch semiconductor or parts with
semiconductor. Please touch an earthed place or wear static electricity
prevention string on wrist.
● Use earthed soldering steel when you connect or disconnect ESD.
● Use soldering-removing tool to break static electricity ,otherwise ESD will be damaged by
static electricity.
● Don't unpack until you set up ESD on product. Because most of ESDs are packed in box and
aluminum plate to have conductive power to avoid static electricity.
● You must maintain electric contact between ESD and plate until ESD is connected
completely to the proper place or a circuit board.
