After mounting, printed circuit boards should be stored and shipped in conductive bags or Containers.
Work platforms, tools, and instruments should be properly grounded.
Working personal should be grounded with resistance of 250 k to 1 M between body and ground.
• Do not apply negative voltages
The use of negative voltages below -0.3V may create parasitic transistors on LSI lines, Which can cause abnormal
operation.
