Precaution
1-2 Static Electricity Precautions
Some semi-conductor parts may be easily damaged due to static electricity.
These elements are generally called as static electricity sense device (ESD). Typically examples of EST include IC, some transistor and chip element for semi-conductor with electrical field effect.
The following methods should be used to reduce damage of elements occurred due to static electricity:
1.Contact and emit all the grounding objects with static electricity from your body before handling with elements for semi-conductor or devices with elements for semi-conductor. You should purchase and use static electricity arm rings or commercially available. You should remove it due to potential shock before supplying power to the device under test.
2.You should place appliance on the conductive surface like aluminum film to prevent that static electricity is accumulated or the device is disclosed outside after removing electrical appliance with the ESD device.
3.You should use only soldering iron that is ground when soldering the ESD device.
4.Minimize physical operation when handling with the ESD device for replacement without packing (Otherwise, namely friction between cloth fibers or lifting of the foot from the carpet floor may cause static electricity enough to damage the ESD device).
